Galvanized Steel Coil
1. Good corrosion resistance: Zinc has high corrosion resistance, which can effectively block the corrosion of steel by air, water, moisture, etc., and prolong the service life of steel.
2. Excellent weather resistance: the zinc layer can exist stably under most environmental conditions, and is not easily affected by oxidation, corrosion and other factors, and has strong durability.
3. Uniform and consistent surface treatment: The galvanized steel coil is uniformly covered with a layer of zinc through the dipping process, so that the surface of the entire steel coil is uniformly treated, and scratches, oxidation and other problems are not easy to occur.
Product description
For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
Product parameters
Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
