DX51D+Z galvanized steel sheet refers to the surface of a layer of zinc plate. Galvanizing is a frequently used and effective method of preserving corrosion.
DX51D+Z hot-dip galvanized steel is accord with EN standard, the first 'D' means this is a kind of steel for cold forming use, the material number of DX51D+Z is 1.0226 , the last 'D' shows the process technology is hot-dip galvanizing, according to different demand from customers, it can be zinc coated (Z), zinc-iron alloy coated (ZF), zinc-aluminium alloy coated (ZA), aluminium-zinc alloy coated (AZ).
DX51D+Z galvanized sheet is also relatively common galvanized sheet. DX51D+Z is a galvanized sheet inside a variety of materials, which can be made with zero spangle or regular flower spangle surface. But only can be used for simple bending and deformation.
