Galvanized steel plate sheet
Galvanized steel sheet refers to a steel sheet with a layer of zinc on the surface for aesthetics and anti-rust purpose. It is most widely used in buildings and also applied as the base metal of color coated steel. Due to the different galvanizing processes, the zinc spangles will be different, including big spangles, regular spangles, small spangles, and zero spangles.
Description
The substrate is hot rolling and cold rolling steel, which is with high strength, good processability, but is easy to corrosion. Through the galvanizing process, it will form a protective layer to prevent the substrate from rusting and prolong its service life. Here is how the zinc coating work: After zinc and oxygen reactions, there will be an oxide film to isolate the substrate from air and moisture to prevent oxidation. If the zinc layer scratches, somewhere around the zinc will melt to protect bare steel from corrosion.

Product Show
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.
