Galvanized Steel
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).
