Q235 Galvanized Steel Plate

Galvanized steel sheet is a galvanized steel sheet that protects the steel from corrosion and oxidation by coating the surface with a layer of zinc. Galvanized Steel Sheets are also easy to weld, form, and drill.Common galvanized steel sheets include hot-dip galvanized steel sheets and electro-galvanized steel sheets. Hot-dip galvanized steel sheet is to immerse the steel sheet in molten zinc solution to form a zinc-iron alloy layer, which has good corrosion resistance; electro-galvanized steel sheet is coated with a layer of zinc on the surface of the steel sheet by electrochemical method, which has good corrosion resistance.  Hot-Dip Galvanizing or HDG is a process in which zinc bonds to steel at the molecular level to produce a four-layer corrosion-resistant finish. The first three layers are zinc-iron alloy layers that are actually harder than the base steel. The fourth or top layer is pure zinc.When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc ox…
