DX51D cold rolled galvanized steel coil made in China
Cold-rolled coil is not heated in the production process, so it don't exist the defect of pitting and iron oxide which often exist in hot-rolled. It has good surface quality, highly polished. Our DX51D cold rolled galvanized steel coil has precise size, uniform thickness, excellent surface quality, and offer good machinability, high strength, low yield limit and good stamping properties.
Standard: AISI, ASTM, BS, DIN, GB, JIS
Thickness: 0.15mm-3.0mm
Width:914mm,1000mm,1200mm,1250mm,1500mm
Length: Customer's Requirement
Tensile strength: 28.1-49.2kgf/mm2
Zinc coating weight: 40g/m2-275g/m2
With excellent cold bending molded manufacture ability, good decoration effect, strong anti-corrosion ability, galvanized steel coils and sheets are also pollution-free and easily recycled. Accordingly, DX51D cold rolled galvanized steel coil can be used as final products and basic plates of color coated steel coils and widely applied in construction, home appliances, decoration, etc.
