Hot Galvanized Steel Square Rectangular Pipes

Galvanized square steel pipe Because the galvanized square pipe is galvanized on the square pipe, so the application scope of galvanized square pipe has been greatly expanded compared with the square pipe. It is mainly used in curtain wall, construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation bracket, steel structure engineering, power engineering, power plant, agricultural and chemical machinery, glass curtain wall, automobile chassis, airport and so on. Hot dip galvanized square tube - hot dip galvanized square tube - hot dip galvanized rectangular tube is used to make molten metal react with the iron substrate to form an alloy layer, which combines the substrate with the coating. For hot galvanizing, the steel pipe shall be decorated to remove the iron oxide on the surface of the steel pipe. After pickling, the tank shall be cleaned with ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the galvanized steel pipe heated in the bath. There are many factors affecting the quality of galvanized strip steel. For example, sulfur will significantly weaken the toughness of steel. The addition of sulfur will easily lead to steel deformation and brittle cracks. Therefore, to ensure the quality of steel, it is necessary to reduce the sulfur content. In addition, phosphorus also has a significant impact on the toughness of steel, which is more severe at low temperatures. Storage location. It cannot be placed in the open air, because it can not only prevent various products from being stolen, but also prevent corrosion. The open-air site is sensitive to various extreme weather conditions. Hot dip galvanized square and rectangular tubes are widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, greenhouse construction and other manufacturing industries.
