Steel is afraid of rusting, so we need to find ways to protect it in order to extend its service life. Before the 18th century, this method was used, such as oiling and painting, but it was not durable and easy to peel off. For small items, copper-clad and tin plated methods are used, but this is too costly. With the development of modern industry, a large amount of steel is exposed to outdoor and humid environments, and there is an urgent need for a method that can protect steel on a large scale.   In 1742, French chemist Melouin conducted an experiment by immersing iron in molten zinc and removing it to form a silver white zinc layer on the surface, which could prevent rust. He published a paper at the Royal Academy of France on the formal birth of hot-dip galvanizing. In 1837 (industrial patent), Sorel of France applied for a patent for hot-dip galvanizing, officially proposing that zinc is more reactive than iron and can "sacrifice itself" to protect steel (cathodic protection principle).   In the same year, Crawford in the UK improved its process by using ammonium chloride as a flux, laying the foundation for modern hot-dip galvanizing technology. In the mid to late 19th century, hot-dip galvanizing became popular: railway tracks, streetlight poles, guardrails, and building components were all made of "black steel" and then hot-dip galvanized.This is galvanised square tubing.   With the explosive demand for urban construction, factories, greenhouses, and guardrails, cold galvanizing (electroplating) emerged at the same time, and electrolytic galvanizing was invented in the late 19th century.The zinc layer is thin, shiny, and inexpensive, giving birth to cold galvanized square steel. In 1931, Polish engineer Sendzimir invented the hydrogen reduction method, a continuous hot-dip galvanizing production line for strip steel. The cost significantly decreased and the quality remained stable. Later, the square tube was directly welded with galvanized steel strip (now the mainstream process).

1、 Smooth surface with inherent metallic luster Due to the smooth surface of the raw cold-rolled strip steel and the uniform and delicate coating. The galvanized square steel produced is also smooth and without roughness, with a high-end metallic texture that does not require painting. 2、 Strong anti-corrosion and long service life Cold rolled strip steel double-sided pre galvanized, with strong adhesion of the zinc layer, not easy to rust. Outdoor humid environments can last for 10-20 years, while indoor dry environments can last even longer. 3、 Strong load-bearing capacity and good toughness Galvanized rectangular tube has strong load-bearing capacity, is not easy to crack, and is not easy to flatten. Suitable for various steel structure projects, with strong load-bearing capacity. 4、 Easy to process Easy to cut, easy to drill, easy to bend, and convenient to customize. Galvanized steel pipes have good ductility and stable welding quality. 5、 Low overall cost The price is cost-effective, eliminating maintenance costs such as painting in the later stage, and long-term use is relatively cost-effective. 6、 Wide applicability Compared to traditional black pipes, black pipes have a wide range of applications. It is mainly used for curtain walls, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power brackets, steel structure engineering, power engineering, power plant agriculture and chemical machinery, glass curtain walls, automotive chassis, airports, etc.

galvanized steel square tubing products Galvanized square and rectangular pipes are made of cold-rolled galvanized strip steel as the basic raw material, which is then unrolled, straightened, and cold bent to create square and rectangular regular cross-sectional shapes. The welded joints are fused through high-frequency induction welding technology, and finally shaped into hollow enclosed section metal profile pipes, belonging to the category of welded steel pipe materials. It is worth mentioning that this product is produced using a galvanized substrate. Compared to pipes that have undergone secondary galvanizing after forming, the distribution of the zinc layer is more uniform and the adhesion is stronger, avoiding the problem of zinc layer detachment from the source. Improved the quality of galvanized pipes.   Advantages of galvanized pipes Galvanized square tube has a significant advantage, as the zinc layer has a unique sacrificial anode self-healing protective property. When the pipe material is cut, scratched, or scratched during the cutting, transportation, and installation process, the exposed zinc element will preferentially undergo oxidation reaction, generating an insoluble stable oxide film that continuously covers and protects the steel substrate, preventing rust from spreading to the periphery and interior. This way, even if the surface of the pipe is damaged, it still has anti-corrosion ability, greatly extending the service life of the pipe.   galvanized steel square tubing compared to traditional black pipe Under the current demand for lightweight, high-quality, and low-cost engineering construction, galvanized square tube has become an indispensable basic profile in steel structure engineering, industrial manufacturing, new energy infrastructure and other fields with mature production technology, reliable product performance, and wide adaptability to various scenarios. It is also the mainstream choice in the industry that balances quality and cost-effectiveness!

In the steel pipe classification system, galvanized steel pipes, oxygen blown welded pipes, wire sleeves, metric welded pipes, idler pipes, transformer pipes, special-shaped pipes, welded thin-walled pipes, and spiral welded pipes are specialized products with clear purposes and technical requirements. The following will be introduced separately.Galvanized steel pipeTo improve the corrosion resistance of steel pipes, general steel pipes (black pipes) are galvanized. Galvanized steel pipes are divided into two types: hot-dip galvanizing and electroplating galvanizing. Hot dip galvanizing has a thicker galvanized layer and superior corrosion resistance; Electrogalvanizing has a lower cost, but the coating is thinner.Oxygen blown welded pipeOxygen blown welded pipes are used for steelmaking oxygen blowing, generally using small-diameter welded steel pipes with specifications ranging from 3/8 inch to 2 inches, totaling eight types. Made of 08, 10, 15, 20 or Q195-Q235 steel strips. To prevent corrosion, some products will undergo aluminum infiltration treatment.ConduitWire conduit is a common carbon steel welded steel pipe used in concrete and various structural power distribution projects, with a commonly used nominal diameter range of 13-76mm. The wall thickness of wire conduit is relatively thin, and it is mostly used after coating or galvanizing treatment, and requires cold bending test.Metric welded pipeThe specifications of metric welded pipes are represented by seamless steel pipes, marked with outer diameter x wall thickness (mm). Made by welding hot-rolled or cold-rolled steel strips of ordinary carbon steel, high-quality carbon steel, or ordinary low-alloy steel, or by hot rolling welding and then cold drawing process.Metric welded pipes are divided into ordinary and thin-walled types: ordinary types are used as structural components (such as transmission shafts) or for conveying fluids; Thin walled products are used for producing furniture, lighting fixtures, and other products. The product must meet the requirements for steel pipe strength and bending test.Roller tubeRoller tube is an electric welded steel pipe used for belt conveyor rollers, generally made of Q215, Q235A, Q235B steel and No. 20 steel, with a diameter range of 63.5-219.0mm. There are clear requirements for the bending degree, perpendicularity between the end face and the centerline, and ellipticity of the steel pipe, which usually require hydrostatic and flattening tests.Transformer tubeTransformer tubes are used to manufacture transformer heat dissipation tubes and other heat exchangers, and are made of ordinary carbon steel. Flattening, expansion, bending, hydraulic and other tests are required. Steel pipes are delivered in fixed or multiple sizes, and there are certain requirements for the bending degree of the steel pipes.Special-shaped tubeSpecial shaped pipes are made by welding ordinary carbon structural steel and 16Mn steel strips, including square pipes, rectangular pipes, cap pipes, etc. They are mainly used for hollow rubber steel doors and windows, agricultural machinery components, steel windows and doors, etc.Welding thin-walled tubeThin walled welded pipes are mainly used to make furniture, toys, lighting fixtures, etc. In recent years, thin-walled tubes made of stainless steel strips have been increasingly widely used in fields such as furniture, decoration, and fencing.Spiral welded pipeSpiral welded pipe is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain helix angle (forming angle), and then welding the pipe seam. This process can produce large-diameter steel pipes using narrow strip steel.Spiral welded pipes are mainly used for transportation pipelines of oil and natural gas, with specifications expressed as outer diameter x wall thickness. Spiral welded pipes are divided into single-sided welding and double-sided welding. The product must ensure that the water pressure test is qualified, and the tensile strength and cold bending performance of the weld meet the specified requirements.

In the steel pipe classification system, seamless steel pipes for low and medium pressure boilers, seamless steel pipes for high-pressure boilers, and seamless steel pipes for geological and petroleum drilling are three important products with clear technical requirements and specialized scenarios. The following will be introduced separately.Seamless steel pipes for low and medium pressure boilersThis type of steel pipe is mainly used to manufacture various low and medium pressure boilers, superheated steam pipes, boiling water pipes, water-cooled wall pipes, as well as superheated steam pipes, large smoke pipes, small smoke pipes, and arch brick pipes for locomotive boilers.The product is made of high-quality carbon structural steel through hot rolling or cold rolling (drawing) process, mainly using 10 # and 20 # steel for manufacturing. In addition to ensuring the chemical composition and mechanical properties, hydrostatic testing, as well as edge rolling, expansion, flattening, and other tests are also required. Hot rolled steel pipes are delivered in a hot-rolled state, while cold-rolled (drawn) steel pipes are delivered in a heat-treated state.Seamless steel pipes for high-pressure boilersSeamless steel pipes for high-pressure boilers are mainly used to manufacture high-pressure and higher pressure steam boiler pipelines and other equipment. The materials used include high-quality carbon structural steel, alloy structural steel, and stainless heat-resistant steel.These boiler tubes are exposed to high temperature and high pressure environments for a long time, and the tubes will undergo oxidation and corrosion under the action of high-temperature flue gas and steam. Therefore, higher performance requirements have been put forward for steel pipes: high durability, high oxidation resistance, and good structural stability.The commonly used steel grades are as follows:High quality carbon structural steel: 20G, 20MnG, 25MnGAlloy structural steel: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etcStainless heat-resistant steel: 1Cr18Ni9, 1Cr18Ni11NbIn addition to ensuring the chemical composition and mechanical properties, high-pressure boiler tubes also need to undergo water pressure tests one by one, as well as expansion and flattening tests. Steel pipes are delivered in a heat-treated state. In addition, there are clear requirements for the microstructure, grain size, decarburization layer, etc. of finished steel pipes.

Steel pipe, as a hollow long strip of steel, occupies an irreplaceable position in modern industry. It is not only the main carrier for bulk fluid transportation, but also an important material in mechanical manufacturing and engineering structures.From the perspective of usage, steel pipes are widely used for transporting fluids such as oil, natural gas, water, coal gas, steam, etc. At the same time, due to the lighter weight of steel pipes with the same bending and torsional strength, they are also widely used in the manufacturing of mechanical parts and engineering structures. In addition, in the field of conventional weapons, steel pipes are often used to produce products such as gun barrels and shells.From a classification perspective, steel pipes are mainly divided into two categories: seamless steel pipes and welded steel pipes (also known as welded pipes). According to the cross-sectional shape, it can be divided into circular pipes and irregular pipes. Among them, circular steel pipes are the most widely used, but irregular steel pipes such as square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal, etc. also have important value in specific scenarios.For steel pipes subjected to fluid pressure, hydraulic tests must be conducted to verify their pressure resistance and quality. It is qualified if there is no leakage, wetting or expansion under the specified pressure. Some steel pipes also need to undergo additional tests such as edge rolling test, expansion test, and flattening test according to standards or customer requirements to ensure their performance.

In the production and selection process of galvanized pipes, size parameters, weight coefficients, and execution standards are key factors that affect product quality and application effectiveness. Understanding these technical indicators can help engineering procurement and design personnel make more reasonable material selection decisions.Nominal wall thickness and weight coefficientThe common specifications for the nominal wall thickness of galvanized pipes include: 2.0mm, 2.5mm, 2.8mm, 3.2mm, 3.5mm, 3.8mm, 4.0mm, and 4.5mm. The corresponding weight coefficient parameters (c) are 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, and 1.028, respectively. This coefficient is used to calculate the actual unit length weight of galvanized steel pipes and is an important reference for cost accounting and structural design.Mechanical properties and commonly used grades of steelThe mechanical properties of steel are the core indicators to ensure the performance of galvanized pipes, mainly depending on the chemical composition and heat treatment process of the steel. In steel pipe standards, tensile properties (including tensile strength, yield strength or yield point, elongation) as well as hardness, toughness and other indicators are specified according to different usage requirements. Some users also require high and low temperature performance.Common steel grades include Q215A, Q215B, Q235A, Q235B. These grades represent different strength levels and applicable ranges, and are widely used in low-pressure fluid transportation and structural pipe fields.Test pressure requirementsAccording to current standards, galvanized pipes need to undergo a hydrostatic test before leaving the factory. The specific pressure requirements are: for steel pipes with an outer diameter range of D10.2mm to 168.3mm, the test pressure is 3Mpa; Steel pipes with an outer diameter range of D177.8mm to 323.9mm are tested at a pressure of 5Mpa. This testing process ensures that the product has sufficient pressure resistance and safety during use.Current national standardsAt present, the main national standards for the production and inspection of galvanized pipes include:GB/T3091-2015 Welded Steel Pipes for Low Pressure Fluid TransportGB/T13793-2008 "Straight seam welded steel pipes"GB/T21835-2008 "Dimensions and Weight per Unit Length of Welded Steel Pipes" The above standards provide clear regulations on the size specifications, allowable deviations, technical conditions, and weight calculation methods of galvanized pipes, which are the technical basis for both production enterprises and purchasers to comply with.Industry insiders suggest that when selecting galvanized pipes, special attention should be paid to wall thickness parameters, brand grades, and whether they meet the latest national standards to ensure project quality and safe use.

In recent years, with the continuous improvement of material durability requirements in construction and manufacturing industries, the application of galvanized steel pipes has become increasingly widespread. Among them, hot-dip galvanized pipes and cold-dip galvanized pipes, as two common galvanized process products, have significant differences in performance, service life, and applicable fields.Hot dip galvanized pipe: alloy layer bonding, strong corrosion resistanceHot dip galvanized pipes are formed by immersing steel pipes in molten zinc solution, causing zinc to react with the iron substrate to form a dense zinc iron alloy layer, thereby achieving a strong bond between the substrate and the coating. During the production process, steel pipes are first pickled to remove surface iron oxide, then cleaned in ammonium chloride or zinc chloride solution, and finally sent to a hot-dip galvanizing tank for galvanizing.The hot-dip galvanizing process has the advantages of uniform coating, strong adhesion, and long service life. Due to the integration of the alloy layer with the pure zinc layer and the steel pipe matrix, forming a tight structure, hot-dip galvanized pipes exhibit excellent corrosion resistance and are widely used in engineering environments with high durability requirements.Cold galvanized pipe: electroplating process, poor corrosion resistance, has been restricted from useCold galvanized pipes, also known as electroplated galvanized pipes, have a galvanizing amount of only 10-50g/m ², much lower than hot-dip galvanized pipes. The galvanized layer is formed by electroplating and is in an independent layered state with the steel pipe substrate, with weak adhesion and easy detachment, resulting in significantly insufficient corrosion resistance.According to industry knowledge, most legitimate galvanized pipe production enterprises do not use electroplating technology to ensure product quality. At present, only some small-scale and outdated equipment enterprises are still producing cold galvanized pipes. Although their prices are relatively low, the product quality is difficult to meet engineering standards.It is worth noting that the national construction department has officially issued a document to eliminate technologically outdated cold galvanized pipes and prohibit their use in water and gas pipelines. Cold galvanized steel pipes are also explicitly prohibited from being used as water supply pipes in new residential projects. summary comparisonHot dip galvanized pipe: uniform coating, strong adhesion, long service life, suitable for high standard engineering.Cold galvanized pipe: low galvanizing amount, easy peeling of coating, poor corrosion resistance, and has been restricted from use by policies

Analysis of Process Characteristics of Cold Galvanized Square Tube: Electrochemical Corrosion Protection, Surface Treatment is KeyIn the series of galvanized square tube products, there are significant differences in the process principle and anti-corrosion performance between cold galvanized square tube (also known as electroplated galvanized square tube) and hot-dip galvanized square tube. Cold galvanizing mainly relies on electrochemical principles to achieve anti-corrosion effects, and its process characteristics determine that it has extremely strict requirements for surface treatment of the substrate. The production of cold dip galvanized square tubes usually uses hollow square tubes formed by cold bending and high-frequency welding as the base tube, followed by electroplating treatment: in the electrolyte, square tubes are used as cathodes and zinc plates are used as anodes, and zinc ions are deposited on the surface of the steel tube to form a galvanized layer through direct current. Unlike hot-dip galvanizing, cold dip galvanizing has a thinner layer (usually several micrometers to tens of micrometers) and no zinc iron alloy layer.The anti-corrosion mechanism of cold-dip galvanized square tubes is mainly based on the electrochemical protection of sacrificial anodes: after the zinc powder comes into full contact with the steel substrate, an electrode potential difference is generated. When the corrosive medium invades, the zinc layer preferentially corrodes to protect the steel. Therefore, to ensure the effectiveness of the cold galvanized layer, it is necessary to ensure a tight bond between the zinc powder and the surface of the steel pipe, which places high demands on the pre-treatment of the steel pipe (oil removal, rust removal, surface roughness, etc.). The main characteristics of cold galvanized square tube include:The surface of the coating is smooth and has a good appearance, suitable for occasions that require painting or aesthetic requirements;The production cost is relatively low, suitable for short-term or indoor use scenarios with low anti-corrosion requirements;However, the coating is thinner and the corrosion resistance is much lower than that of hot-dip galvanized square tubes, making it unsuitable for long-term use outdoors or in humid environments.Due to the limitations in thickness and durability of the cold galvanized layer, it is generally recommended in the industry to prioritize the use of hot-dip galvanized square tubes for outdoor structures, high humidity environments, or projects requiring long service life; Cold galvanized square tubes are more suitable for indoor frames, temporary facilities, or low corrosion environments.

Galvanized square tube is a commonly used structural material in fields such as construction, machinery, and agriculture, and its production process directly affects product quality. Among them, hot-dip galvanized square tubes are favored by the market due to their uniform coating, strong adhesion, and excellent corrosion resistance.It is understood that the production of hot-dip galvanized square tubes usually adopts two process routes: one is to use hot-rolled or cold-rolled galvanized steel plates and coils as raw materials, and then weld them into hollow square tubes at high frequency after cold bending; The second method is to first make cold-formed hollow steel pipes, then immerse the steel pipes in a hot-dip galvanizing pool for hot-dip galvanizing treatment, and finally obtain square rectangular galvanized pipes. The core process of hot-dip galvanized square tube lies in the hot-dip galvanizing process: the welded square tube is subjected to pre-treatment such as degreasing, acid washing, plating assistance, and drying, and then immersed in molten zinc solution (temperature about 445-465 ℃), causing a series of physical and chemical reactions between the surface of the steel tube and the zinc solution, forming a dense layer of zinc iron alloy and pure zinc layer. This coating not only physically isolates corrosive media, but also has cathodic protection function, which can prevent the substrate from rusting even if it is locally damaged.The main characteristics of hot-dip galvanized square tube include: ☞The production process is relatively simple, the production efficiency is high, and the product specifications are diverse;☞The threshold for equipment and capital investment is relatively low, suitable for large-scale production, especially welcomed by small and medium-sized galvanized square tube production enterprises;☞The coating thickness is uniform, the adhesion is strong, and the corrosion resistance life is long. It should be noted that in terms of strength indicators, hot-dip galvanized welded square pipes are lower than seamless square steel pipes, but they fully meet the requirements in most ordinary structural applications. At present, hot-dip galvanized square tubes are widely used in building frames, guardrails, solar brackets, agricultural greenhouses, vehicle manufacturing and other fields.

In the fields of manufacturing and engineering construction, a square or rectangular hollow steel pipe made of cold-rolled galvanized strip steel refined by high-frequency welding is becoming a key material supporting modern industrial and urban development due to its excellent comprehensive performance. The core value of this product, known as galvanized square tube, lies in combining the strength of steel with the long-term anti-corrosion intelligence of zinc layer, thus breaking through the application limitations of traditional black tubes.Through advanced technology, galvanized strip steel is processed and welded into precisely sized hollow sections. This design not only achieves the optimal mechanical distribution of the material, endowing the profile with excellent bending, torsion, and load-bearing capabilities, but also provides dual protection with the galvanized layer on its surface: it serves as a physical barrier to isolate corrosion and actively protects the substrate through electrochemical principles. This "active+passive" durability feature enables it to handle various harsh environments with ease.Therefore, the application scope of galvanized square rectangular pipes has been widely expanded. It is not only the main skeleton of building curtain walls and steel structures, but also deeply involved in mechanical manufacturing, power facilities, and the automotive industry; From the grand roof that supports the airport terminal, to the precise array of brackets that make up the solar power plant, and to the sturdy backbone that transforms into an agricultural greenhouse, its presence is everywhere.
