1. Detailed introduction of galvanized coil:
Galvanized coil refers to the thick steel plate with a layer of zinc on the surface. Galvanizing is a reasonable anti-corrosion method for economic development. About half of global zinc production is used for such processing processes.
2. Efficacy of galvanized coil:
Galvanized coil is used to avoid corrosion of thick steel plate surface to increase its service life. A layer of metal material zinc is coated on the surface of thick steel plate. This kind of galvanized thick steel plate is called galvanized coil.
3. Main uses of galvanized coils:
Galvanized coil is suitable for engineering construction, household appliances, cars, utensils, transportation and ancestral industries. It is very popular in steel structure engineering, automobile industry, steel warehouse manufacturing and other manufacturing industries.
4. The key characteristics of galvanized coil are:
Strong corrosion resistance, good process performance, benefit from production and processing, high cost performance.
5. Specification and model of galvanized coil:
Relevant product executive standards indicate the thickness, length, total width and allowable error of the specification strongly recommended for galvanized coils. The thickness error of galvanized coil is generally 0.05mm, the width error is generally 5mm, and the thickness of the plate is generally between 0.2-3.2.

Hot dip galvanized pipe is used to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the hot-dip galvanized steel pipe substrate and the molten plating solution, forming a corrosion resistant zinc iron alloy layer with compact structure. The alloy layer is integrated with pure zinc layer and steel pipe matrix, so its corrosion resistance is strong.
Hot dip galvanized steel pipes are widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
