Why need a liner power steel pole? How can a power steel poles be done well? This is a common problem. Why do you have to repeat it? It is because a manufacturer does not often ask this question, but it is very dangerous to eat it. As a futao`s power steel poles, We should constantly reflect on continuous progress, actively introduce advanced technology, and timely talents, while taking into account national policies. Only in this way can we make electric steel poles better. At the time of purchase, many people will pay attention to the power steel poles manufacturers, and good manufacturers can bring high-quality products. The technology of the manufacturers in production is very important. When manufacturers can design and manufacture according to requirements, they can bring high-quality products. Good manufacturers never make a fuss about raw materials, and manufacturers will choose high-quality steel products. When we notice the price of electric steel poles, we will find that the prices of many manufacturers are different. When choosing the products we need, we not only need to pay attention to the reputation of the manufacturers, but also need to pay attention to the quality of the products. In order to ensure the performance in use, we need to buy high quality electric steel poles. Why do you need a linear power steel poles? Do you understand? The characteristics of the power steel poles material are: whether the label of the selected material of the power steel poles meets the national material standard, the strength of the selected material, the waywardness, and the salt and alkali resistance, corrosion resistance, etc. In order to chase unfair profits and reduce the material standards for electric steel poles, this kind of behavior is very dangerous. Our factory resolutely put an end to this behavior and insisted on using high-quality steel plates of steel No. 315 to ensure better quality service to customers. The characteristics of the power steel poles material are as follows: 1. For the concrete material in the manufacture of electric steel poles, it is mainly used in large-scale photovoltaics. This material has many characteristics, and it can only be placed in the wild and needs to be installed in areas with better basic conditions. The material not only has high stability, but also supports larger panels. 2. For the steel material in the manufacture of electric steel poles, it has been widely used in power stations, which has good stability, mature manufacturing process, high bearing capacity and easy installation; secondly, this material often has specifications. It is also relatively uniform and its performance is very stable, especially in terms of appearance and anti-corrosion performance. 3. For the aluminum alloy material in the manufacture of electric steel poles, the material has good corrosion resistance, the quality is often lighter, and the appearance is better.

How steel pole manufacturers to develop depends on the market needs of this industry, but the market of this industry is determined by the majority of users, a steel pole manufacturers want to survive to build a can let the majority of users accept and recognize the brand. Steel pole factory for the ppoleuct brand is the creation of a more amateur, industry market environment is one of the important factors that influence on the nature of the same market, steel pole manufacturer not too can play the original ppoleuct brand effect, steel pole manufacturer if put too much energy on ppoleuct brand building, it also can make the steel pole factory business losses. Nowadays, in the current under the condition of market competition and the pressure is so intense, a lot of electric steel pole ppoleucers involved in electric steel pole have to do it in the ppoleuct price is also helpless, because of the lack of strength, electric steel pole manufacturers have also for their own survival and development, in desperation can only choose low price competition to maintain.But low price competition can not be taken as a long-term solution, power steel pole manufacturers should also on the basis of their own reality, to understand the market demand, targeted to meet the needs of target customers. At the same time, power steel pole manufacturers should also learn from each other, take the road of enterprise own characteristics, create differentiated competition, in the future development to give full play to the enterprise's own competitive advantage, only in this way, power steel pole manufacturers can go further. Power steel pole manufacturers in power steel pole ppoleuction, must always use quality and environmental protection and health of raw materials, improve the manufacturer's ppoleuction and manufacturing technology level, to create environmental protection and health power pole ppoleucts;In terms of ppoleuct sales, the power steel pole manufacturers should be closer to the psychology of the majority of users, with careful and thoughtful pre-sales and after-sales service to conquer the majority of users, according to their various needs, to provide advice suitable for users. Power steel pole manufacturers only their sincerity to the user, can be trusted to show, in order to basically eliminate the vast number of users psychological defense line, let them build up trust to manufacturers, so that the power steel pole industry can have a better development and the future.In a word, trust is the most important part of power steel pole sales.

What Makes Electric Steel Poles Better Than Traditional Cement Ones? Some electric steel bar factory, all in the name of low prices to deceive the masses of users, to the inferior quality has confusion of ppoleuct quality in the heart of the customers is very difficult to make the whole industry to build credibility, manufacturer for profiteering, but ignore the quality of the ppoleuct and security, it's not just the irresponsibility of the masses of users, or an act of short-lived, and such are killing each other between electric steel pole manufacturer, after will hurt the development of the industry. Electric steel pole manufacturer wants to get rid of difficulties, enhance the level of industry and technology innovation is the fundamental law, only in the function of the ppoleuct and the service life and so on several aspects to be able to go to the innovation, using new technology to create ppoleuct differentiation and humanized ppoleucts, innovation, is the only way to open the market, get more user's trust and favor. Our factory is Yixing electric power steel pole manufacturers, mainly to meet the needs of people's lives.We are looking forward to cooperating with you on the quality assurance of electric steel pole ppoleucts Some users may not be particularly familiar with the application field of electric steel pole in their daily life.The electric steel pole industry has helped us in every aspect of our daily life.In the purchase of electric steel pole ppoleucts, manufacturers will be based on the needs of users and ppoleuct application fields and other aspects from a variety of ppoleucts to choose the real suitable ppoleucts for users. Now, we all know that electric steel pole brings us a lot of convenience, so electric steel pole in our application reflected the effect is better than the ordinary electric steel pole effect, then on the application of electric steel pole than the traditional cement pole is better. Because the concrete pole is made of cement, the domain of itself will not very stable, can't for reinforcement, but what we ppoleuce electric steel pole materials used are high quality, not with cement to ppoleuce electric steel pole, turf is reinforced, so on the application effect is unmatched by traditional concrete pole, use the effect will be very good.The price of our electric steel pole is very reasonable.

Do You Know The Transportation And Storage Of Steel Pole For manufacturer? Transportation and storage of power steel pole for manufacturers: 1. It is strictly prohibited to drop power steel pole or steel pole disk with steel pole from a height during transportation, especially at a lower temperature (generally about 5℃ or below). Throwing or dropping power steel pole may cause insulation and sheath cracking. 2, as far as possible to avoid in the open air with naked storage of power steel pole, steel pole plate is not allowed to be laid flat. 3, lifting the electrical steel pole packaging, it is strictly prohibited to lift several plates at the same time.In vehicles, ships and other means of transport, electric power steel pole plate to be fixed with appropriate methods to prevent collision or overturned, to prevent mechanical damage to the steel pole. 4, power steel pole is strictly prohibited from contact with acid, alkali and mineral oil, to be separated from these corrosive substances storage.No harmful gas that damages insulation and corpolees metal is allowed in the storeroom where electric power steel pole is stored. The waste of power steel pole ppoleuction is still everywhere, but we often turn a blind eye to it. The discovery of waste needs the help of scientific management to see clearly. It is necessary to split the value chain of power steel pole enterprise, list each activity in detail, and then analyze each activity. Therefore, to make the cost of power steel pole compression business, to strengthen the survival of compression or cut off the low profitability of the business, to strengthen the core competitiveness, to strengthen the power steel pole business viability is also major. Now that we know that survival is the top priority in an economic crisis, power steel companies need to restructure their businesses to reduce or eliminate less profitable businesses in order to focus resources on businesses that are ready to cash out.Because the future development of electric power steel pole enterprise is not clear, the development of new business must invest capital, and constantly put in a variety of resources.

Do You Know The Advantages Of Electric Steel pole? It requires perseverance for electric steel pole manufacturers to fulfill their responsibilities. Employees are an important carrier of enterprise culture of electric pole manufacturers, and the role of managers of electric pole manufacturers determines the cultural outlook of employees to a greater extent. Electric pole factory managers not only at work to obey the system process specification, and consciously practice the company corporate culture, adhere to corporate culture values and behavior standards, making the decisions, job assignments, staff management, job evaluation, and communication, in dealing with the relationship between up and down, to consciously consider the electricity pole culture standard of manufacturer, proper balance conservative and enterprising, opportunity and risk, efficiency and cost, specification and quality and efficiency, individual and group, the whole and part, social responsibility and power pole manufacturers profit, etc. Various relationships. 1. Beautiful appearance of steel pole This is another major advantage of steel poles. In the current wave of urban construction and transformation, whether the city is beautiful or livable is also increasingly concerned by residents.Thus urban construction more and more high to the requirement of electric power line construction, which also performed at the request of the beautiful sex, especially some more strict with this aspect of the urban landscape road, and the traditional tower that it is difficult to meet the requirements of steel pole because of its compact structure, beautiful image small, so you can basically meet the requirements of aesthetics. 2. Steel pole construction is simple and quick Establish traditional tower construction must have a set of process of the tower, regardless of the overall group or section towers, time limit for a project are similar, and the steel bar construction does not need to form a basic process, only need to install the steel pole cross arm after the completion of the whole group can be immediately, construction speed is much faster than the Eiffel Tower construction, in general, a construction team can set a day appointed tower 1.5 ~ 2 base, and a day to stand around 10 base steel pole, so using steel pole can greatly improve the efficiency of construction, shorten the construction period. 3, steel pole material is not easy to steal The loss of tower material has been a major problem in the safe operation of the tower. Although some preventive measures have been taken, such as installing anti-theft bolts under 6 meters, tower material loss still occurs from time to time.Steel pole because of the whole plug or flange connection, so basically put an end to the phenomenon of missing parts, reduce the potential accident, improve the line health level. Electric power steel bar in addition to the above has a little short poleuction cycle, can withstand greater stress and other advantages

Wide range of applications for steel Poles It is crucial for power steel rod manufacturers to enter new markets and have good sales channels. Power steel rod manufacturers should have special marketing methods and strategies, as well as high-quality channel providers. The selected channel vendors must have software and hardware. The software is the channel business philosophy and the product brand recognition. It is highly concerned with the management methods of the power steel rod manufacturers and the brand marketing of the products. The hardware aspect is that the capital strength of the selected channel providers and the capacity of the warehouse logistics are in line with the needs of the power steel rod manufacturers. In all kinds of power engineering, the use of electric poles in the installation of electric wires is started with cement poles. Nowadays, more and more users choose steel poles. The use of steel poles is wider and wider. I will tell you about the reasons why steel bars are widely used. The steel rod is made of steel and is made of steel. Compared with the traditional cement pole, the steel rod is lighter in weight. It is convenient to install the wire or carry it. Carrying a lot of utility poles at a time can satisfy the needs of various construction areas. The manufacturer tells you the reasons for the wide application of steel poles. Steel rod manufacturers consider that most of the utility poles will be installed in the suburbs, and the various corrosions are severe. Therefore, the anti-corrosion treatment of the steel poles such as galvanizing also prolongs the service life of the steel poles and also reduces the part. Maintenance costs. The appearance of the traditional cement pole is an upright pole, and the wires at the top of the raft are distributed in parallel. It is easy to entangle with each other due to strong winds, and the safety hazard is also large. Steel rod manufacturers divide the produced poles into multiple layers, and separate the wires according to different levels, which reduces the possibility of entanglement between the wires and improves the safety performance. This is also the reason why steel bars can be widely used. The reason for the application.

General Requirements Of Steel Pole Structure And Design Of Electric Steel Pole General requirements for steel pole structure: The steel pole is generally made of Q235 and 16Mn, etc., and its section shapes are mostly round and 12-sided, and the pole body is mostly conical. In general, the slope of the pole is 1/75 ~ 1/70, and the 30° Angle is 1/65 and the 60° Angle is 1/45 and the 90° Angle is 1/35.The tip diameter of the steel pole is generally 200 ~ 260mm, which can be determined according to the design calculation, and most commonly used steel pole tip diameter is 230mm. There are two kinds of joint modes of multi-section bar, flange connection and socket connection, which can be selected according to the actual situation.For deflection, the straight steel bar should not be more than 5 percent, the Angle bar should not be more than 2 percent.Steel bar foundation is mostly large stepped reinforced concrete foundation, and other foundation forms such as cast-in-place pile foundation can also be used in special areas. Electrical steel pole design: now countries are not unified standards and design about steel bar method, and the steel bar manufacturer has some molding experience and a large number of experimental data, so the steel pole body and foundation design are usually by design personnel to provide the corresponding technical data, and the steel bar manufacturer is responsible for the design, the design is completed by the designer is responsible for checking again. 1. The technical data to be provided by the designer to the pole factory mainly include the following aspects: 1) basic information of the line: including voltage grade of the line, line return number, line arrangement mode, bar type, Angle degree, call height, type of conductor (lightning conductor), safety factor, horizontal and vertical distance, regular distance and meteorological conditions of the area through which the line passes, the corresponding head design size should be provided. 2) the number of steel pole: the specific number of steel pole of various types, Angle degrees and calling heights should be provided in detail.3) local soil conditions: including soil type, freezing depth, soil calculation Angle, soil bulk density, ground endurance, groundwater level, etc., for the purpose of basic design.

With the rapid development of steel pole industry in China, the level of mechanization is constantly improving, greatly improving the steel pole project construction progress and construction quality.The service life of steel pole is the basis to ensure the construction progress. For electric steel pole maintenance can prolong the service life of steel bar can also improve the work efficiency of the steel pole and contractor should be detailed maintenance plan, and should intensify their efforts to implement because urgent task, to put an end to abandon in the construction of steel pole and maintenance work, on the contrary in the mission when the larger amount of homework more attention should be paid to the maintenance of steel bar to ensure that the steel bar can have a good working condition, also can reduce the occurrence of failure probability. With the gradual increase of the technical content of steel pole in modern construction, the relevant knowledge required by operation and maintenance personnel should also be improved correspondingly. Therefore, in the process of steel pole management, it is crucial to improve the quality of staff The quality of electric power steel pole is more and more important for enterprises. The quality of electric power steel pole reflects whether an enterprise has core competitiveness or not. Improving the quality of ppoleucts is an important means to ensure that the enterprise occupies the market and can continue to operate. If electric power steel pole manufacturers want to become bigger and stronger, they must enhance their innovation ability and make efforts to improve the quality and service level of electric power steel pole, which is also an important auxiliary method for enterprise survival.Especially in the current situation of fierce competition, the improvement of the quality of electric steel pole has become an important issue concerning the survival of enterprises. It can be seen that the importance of the quality of electric steel pole is becoming more and more prominent, so the quality of ppoleucts has become an important issue that must be considered by the current electric steel pole enterprises if they want to develop for a long time.

Power steel pole manufacturers going to enter the new market, a good sales channel is crucial.Electric steel pole manufacturer should have special marketing methods and strategies, must have the high quality distributors, the distributors must be chosen to have hardware and software, software is the management idea of distributors and ppoleuct brand recognition and electric steel pole to the height of the operation method and the ppoleuct brand marketing with, hardware is the choice of channel, financial strength and warehousing logistics capability to meet the demand of electric steel pole manufacturer. In all sorts of electric power project erecting electric wire should use telegraph pole, begin is the telegraph pole that USES cement material to pledge, go choosing steel pole more to broad user now, the use range of steel pole is wider and wider, manufacturer of electric power steel pole tells about the reason that steel pole applies extensively to you. Steel pole is the telegraph pole that steel is material ppoleuction and become, compare with the telegraph pole of traditional cement material, steel pole material is a bit lighter, no matter be erecting electric wire or carry more convenient, can carry a lot of telegraph pole when construction, can satisfy to need at each construction area Steel pole manufacturers consider that most of the poles will be installed in the suburbs, by a variety of corrosion is more serious, so the steel pole galvanized and other anti-corrosion treatment, also extend the service life of the steel pole, will also reduce part of the maintenance costs. The appearance of a traditional cement pole is an upright pole, and the wires at the top are distributed in a parallel state. It is easy to get entangled in each other because of strong wind, which is also a big safety hazard.The steel pole manufacturer divides the poles into several layers. According to different layers, the wires are separated, which reduces the possibility of entanglement between the wires and improves the safety performance. This is why the steel pole can be widely used.

Where is the power steel poles better than the traditional concrete poles? Some power steel poles factories use the low price banner to deceive the users with inferior quality. The quality of the chaotic products makes it difficult for the whole industry to establish credibility in the hearts of the users. The manufacturers have neglected in order to make huge profits. The quality and safety of the products are not only irresponsible to the majority of users, but also a short-lived behavior, and such mutual killing between power steel poles manufacturers will also hurt the development of the entire industry. Power steel poles manufacturers want to get rid of the difficulties and improve the industry level. Technological innovation is the root of the law.

Various cases and analysis of incomplete penetration Incomplete penetration refers to defects caused by the fact that the base metal does not melt and the weld metal does not enter the joint. According to the welding method of the welded parts, the roots are not welded and the middle is not welded. The root is not welded because the liquid weld metal does not enter the blunt edge of the root, and most of it exists in the single-sided welding of the V-shaped or U-shaped groove. The middle is not welded because the liquid metal does not enter the middle blunt edge, and most of it exists in the double V-shaped or double U-shaped groove double-sided welding. (The weld is not welded to the defect) The lack of penetration in the weld will reduce its effective area and seriously reduce the mechanical properties such as the strength of the welded parts. Incomplete penetration will also cause stress concentration and severely reduce the fatigue strength of the weld. In addition, when the welded part is under load-bearing stress, it may develop into a crack if it is not welded, and may eventually cause the weld to crack. The incomplete penetration is more harmful than the defects such as pores, slag inclusions and tungsten traps, which are harmful defects. The following two figures show the submerged arc welding seam of the base material thickness of 8-15mm, and the overall gouging weld seam is not welded. (not welded in the weld) Causes of incomplete penetration: 1) The welding current is small and the melting depth is shallow; 2) The groove and gap size are unreasonable, and the blunt edge is too large; 3) magnetic biasing effect; 4) The eccentricity of the electrode is too large; 5) Poor cleaning between layers and roots. Using a larger current for soldering is the basic method to prevent under penetration. In addition, when welding the fillet weld, replace the direct current with alternating current to prevent magnetic partial blow, rationally design the groove and strengthen the cleaning, and use short-arc welding and other measures to effectively prevent the occurrence of incomplete penetration. Unwelded film image features (1) The typical image that is not penetrated is a thin straight black line. The contours on both sides of the defect are neat, which is the machining mark of the blunt edge of the groove. The width of the unwelded image is just the width of the gap of the blunt edge. (the root is not penetrated) (2) Sometimes the blunt edge of the bevel is partially melted, the outline of the image becomes less tidy, and the width and blackness of the defect image are locally changed. However, as long as it can be judged to be a linear defect at the root of the weld, it is determined to be unwelded. through. (not welded) (3) The position of the projection on the base of the weld is not penetrated. Generally, in the middle of the weld, it may be biased to one side due to the reasons of transillumination and welding. (4) The incomplete penetration is intermittent or continuous, and sometimes it can penetrate the entire negative film. The following is the actual working radiation detection film image (not penetrated and rounded defects) As shown in the above figure, the non-penetration defect has a straight black line in the film and is at the center of the weld, which can be surely determined to be a defect of incomplete penetration. (not penetrated and rounded defects) As shown in the above figure, it can be clearly seen from the figure that there are many circular defects (circular vents) in the center of the weld. It can be seen carefully that a black line at the center of the weld connects the circular defects together. The black line is the unpenetrated image. The information from Another source

Hot-Dip Galvanizing to ASTM A123 Fact Sheet Hot-dip galvanizing (HDG) is the process of dipping fabricated steel into a kettle or vat containing molten zinc. While the steel is in the kettle, the iron in the steel metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to steel. The hot-dip galvanizing (HDG) process consists of three basic steps:  Surface Preparation  Galvanizing  Inspection Power Pole Surface Preparation Surface preparation is a critical step in the application of any coating. The galvanizing process has its own built-in means of quality control because zinc will not react with an unclean steel surface. Any failures or inadequacies in surface preparation will be immediately apparent when the steel is withdrawn from the zinc bath because the unclean areas will remain uncoated, and immediate corrective action can be taken. Surface preparation for galvanizing consists of three steps: Degreasing/Caustic Cleaning A hot alkali solution, mild acidic bath, or biological cleaning bath removes organic contaminants such as dirt, paint markings, grease, and oil from the metal surface. Epoxy, vinyl, asphalt, or welding slag, which cannot be removed by degreasing, must be removed before galvanizing by grit-blasting, sand-blasting, or other mechanical means. Pickling A dilute solution of heated sulfuric acid or ambient hydrochloric acid removes mill scale and iron oxides (rust) from the steel surface. As an alternative to or in conjunction with pickling, this step can also be accomplished using abrasive cleaning or air blasting sand, metallic shot, or grit onto the steel. As long as the surface of the steel is completely cleaned to bare metal and all non-metallic substances removed, the galvanizing reaction is indifferent to the manner of cleaning. Fluxing The final surface preparation step in the galvanizing process, a zinc ammonium chloride solution, serves two purposes. It removes any remaining oxides from the surface of the steel, and deposits a protective layer on the steel to prevent any further oxides from forming on the surface prior to immersion in the molten zinc. Steel Pole Structure Galvanizing During the actual galvanizing step of the process, the material is completely immersed in a bath of molten zinc. The bath chemistry is specified by ASTM A123 and requires at least 98% pure zinc by weight maintained at a temperature above the melting point of zinc. The zinc metal in the bath must meet the requirements of ASTM B6 or ASTM B960. While the steel is immersed in the kettle, zinc reacts with iron in the steel to form a series of metallurgically-bonded zinc-iron intermetallic alloy layers, commonly topped by a layer of pure zinc metal from the bath. Once the fabricated items` coating growth is complete, it is withdrawn slowly from the galvanizing bath, and the excess zinc is removed by draining, vibrating, and/or centrifuging. The metallurgical reaction will continue after the materials are withdrawn from the bath, as long as the steel part remains near bath temperature. Galvanized articles are cooled either by immersion in a passivation solution or water, or by being left in open air. Metal Power Pole Inspection The inspection of hot-dip galvanized steel is simple and quick. The two properties of the hot-dip galvanized coating most closely scrutinized are coating thickness and appearance/surface condition. A variety of simple physical tests can be performed to determine thickness, uniformity, adherence, and appearance. Fabricator -- Controllable Variables To promote the best possible outcome from the hot-dip galvanizing process, the fabricator should consider controlling several variables which impact the coating appearance and characteristics. Steel with a specific chemistry is known to most often result in a galvanized coating with a coating thickness above the minimum specified in ASTM A123. Steel with silicon and phosphorous outside the ranges prescribed in ASTM A385 can result in excessively thick zinc coatings which can lead to delamination when impacted by outside forces during handling and erection. Bath additives are often used to minimize the coating growth to a level near the minimum thickness but are not effective for all steels. Decreasing the immersion time in the molten zinc to result in a thinner zinc coating is not always possible. Steel with properly designed vent and drain holes, cropped gusset plates, and seal-welded overlapping surfaces as prescribed by ASTM A385 will most often result in a galvanized coating without excess zinc buildup inside or outside the steel article. Optimal immersion and removal speed from the molten zinc bath is a slow, steady rate. This allows even heating during immersion and even freezing of the zinc during removal. Too few or too small drain and vent holes make immersion and removal very slow and inefficient, and the result is a very uneven coating. Poor seal welds or stitch welding causes `blowout` of trapped chemicals from the overlapped surfaces and steel around the weld area may remain ungalvanized. Welded steel free of flux and slag and the use of weld rod similar in chemistry to the steel being welded. Residual flux and slag are not always visible to the galvanizer and are not removed during the chemical cleaning steps. The result is ungalvanized areas around the weld. If the weld rod is dissimilar in chemistry to the steel being welded, the zinc reaction with the weld metal will likely yield a different appearance and different coating thickness compared to the steel members. Stress-relieving steel/weld bead near the area of flame-cut cope edges. The thermal gradient inherent in the galvanizing process affects the residual stresses in structural steel caused by flame cut copes. If there is no stress-relieving prior to galvanizing, the cope cut areas may exhibit cracks after galvanizing. The fabricator may alternatively place weld bead on the beam web adjacent to the cope area, thereby relieving some of the residual stress in this area. Minimize cold-working, but if necessary, do it in accordance with recommended bend radius. Cold-working induces stress into structural steel and the excess residual stress can age the steel at galvanizing temperatures, thereby changing the steel properties. The heat of the galvanizing process accelerates the appearance of cracks but does not cause the cracks. Use removable steel tags, weld bead, or stenciling to mark fabricated pieces. Paint, lacquer, and some marking pen material are not removed in the cleaning process and must be removed mechanically prior to beginning the galvanizing process. Fabricator -- Uncontrollable Variables Steel production is not a precise process in terms of resulting chemistry and an even distribution of elements throughout. Some fabrications combine steels of varying chemistry and thickness. Both influence the outcome of the galvanized coating appearance and the implications for the fabricator are as follows. Fabrications using two or more steel thicknesses of the exact same chemistry One of the advantages of hot-dip galvanizing is total immersion so there is complete protection of all steel surfaces, tight joint areas, and internal spaces. When a fabrication comprised of two or more steel thicknesses is immersed, the thinner steel heats up to the bath temperature sooner than the thicker steel. The reaction time between the iron in the steel and the zinc will be different and may result in two quite different appearances ranging from bright/shiny to matte gray. Fabrications using steel with two or more different chemistries The metallurgical reaction rate between the molten zinc and each of the steel types may be quite different and result in both a different coating thickness and a different appearance, despite each part of the assembly being immersed in the same bath for the same amount of time. There is no way to modify the immersion time so as to produce a uniform coating thickness or appearance. Fabrication volume insufficient to be galvanized in a compatible batch To be as productive and efficient as possible, galvanizers will combine several jobs, which may contain quite different steel thickness and chemistries amongst its articles, and use wire to suspend the steel from a rack used to immerse all of the parts into the cleaning and molten zinc baths at one time. There is no way to predict or ensure the appearance of the various steel pieces will be consistent. Even if all the steel articles were of the same thickness and an exact immersion time for that specific thickness was used, the coating thickness and appearance from piece to piece may be quite different. Steel with a homogeneous chemistry where all elements are evenly distributed throughout the steel article Both the continuous cast and traditional iron ore/coke/limestone methods of producing steel do not guarantee the chemistry of the steel as reported on the mill test report is consistent throughout a beam, plate, or tube. In fact, it is normal for the chemistry from Point A to Point B on a structural steel piece to be slightly different. This difference in silicon and/or phosphorous, the two elements in steel causing the most reactivity between the iron and the molten zinc, often results in a different galvanized coating thickness and/or appearance on the same piece of steel. Even if the chemistry were precisely known and 100% homogenous throughout the piece of steel, having a prescribed immersion time and molten zinc temperature does not guarantee a predictable outcome. There are other unknown elements in the steel and possible rolled or fabricated stresses induced in the steel which may cause an area of matte finish adjacent to an area with a bright and shiny finish. Galvanizer Variables Extensive research and testing by the galvanizing industry has resulted in best practices which are not 100% predictive of coating appearance and thickness, but deliver the most consistent quality within the parameters the process allows for the variety of materials being galvanized. This is what we know. The use of special high-grade, high-grade, or prime western zinc, produced from raw ore or via the re-melting of secondary zinc, does not guarantee a particular appearance or thickness. The addition of a small amount of nickel to the molten zinc bath helps to control the reactivity between iron and silicon as well as iron and phosphorous for some steel chemistries but a specific range of coating thickness is not predictable for any thickness of steel. The addition of aluminum to the molten zinc bath generally results in a shinier zinc coating, but does not guarantee there will be no matte coating appearance on a part or all of a steel piece. There is no way to measure the degree of mill scale and corrosion on a piece of steel prior to immersion in the cleaning process tanks. Thus, the amount of time for the steel to reside in the acid bath is determined by experienced operators and is not available from a table of values. Pickling with hydrochloric or sulfuric acid are both effective means of removing mill scale and rust. Over-pickling is possible when using sulfuric acid but the resulting zinc coating is only marginally thicker than had the pickling time been exact. Galvanizers are careful to not over-pickle because applying excess zinc makes the production less economical. Immediate water or passivation quenching after the steel is removed from the galvanizing bath stops the reaction between the iron and zinc, usually resulting in a shinier coating, but not always. For tubular products, the quenching cools the material quickly and typically prevents peeling, i.e. the separation of the pure zinc outer layer of the coating from the alloy layers. Based on symmetry and steel thickness, some fabrications cannot be water quenched due to concerns related to distortion. Galvanizers regularly test and adjust the strength of their acid and flux solutions, and either completely change them out or employ a filtering system to maintain their effectiveness. Any variance from the optimal strength and/or cleanliness only affects the efficiency of the process and not the quality of the galvanized coating. If the flux fails, then this is immediately visible as ungalvanized areas on the fabrication right after removal from the zinc bath. Galvanizers regularly remove zinc-iron compounds called dross from the bottom of the galvanizing kettle where they settle over time. Effective [drossing" is important to maintain the kettle in proper working order and also minimizes the amount of dross that could potentially end up on the galvanized steel as it is removed from the kettle. The frequency of [drossing" the kettle is a function of how much steel volume is being processed and the cleanliness of the flux cleaning solution. This is an involved process and production cannot be done while [drossing;" thus, galvanizers are flexible on scheduling the drossing to ensure they meet customer demand. Prior to steel articles and fabrications being removed from total immersion in the zinc bath, galvanizers paddle zinc skimmings (zinc-oxide) to the side of the kettle so very little, if any, skimmings settle on top of the newly galvanized surface during removal from the bath. Because the oxidation of the molten zinc is a continuous process, it is not always possible to have all surfaces completely free of skimmings. Copyright 2017 American Galvanizers Association.

When you passerby the Electric Poles on the road have you ever noticed them?Do you realize the differences of different Electric Poles?Today,let me show you three types of Electric Pole. 1.Wooden poles These are made of seasoned wood and are suitable for lines of moderate X-sectional area and of relatively shorter spans.Such poles are cheap,easily available,provide insulating properties and,therefore,are widely used for distribution purposes in rural areas as an economical proposition. 2.Steel poles The steel poles are often used as a substitute for wooden poles.They possess greater mechanical strength,longer life and permit longer spans to be used.Such poles are generally used for distribution purposes in the cities.They need to be galvanised or painted in order to prolong its life. 3.RCC poles The reinforced concrete poles have become very popular as line supports in recent years.They have greater mechanical strength,longer life and permit longer spans than steel poles.Moreover,they give good outlook,require little maintenance and have good insulating properties.But the main difficulty with the use of these poles is the high cost of transport owing to their heavy weight. In the above three types of pole,the Steel Pole seems like the best choice,it has longer life when compare to wooden pole,and cheaper than RCC pole.Here comes the question,where can we get the high quality and inexpensive Steel Poles?Please take look at Yixing Futao Metal Structural company,China.We manufacture all kinds of steel poles and steel towers,such like Steel Electric Pole,Steel Light Pole,Electric Transmission Pole and so on.You surely will get what you need at here.
