The Galvanized/Galvalume Coil produced by our company is coated with a layer of zinc as the main rawmaterial on the surface of the cold-rolled sheet. Galvalume Coil is widely used in building materials decoration(composite panelsqlass tiles,rolling doors),daily necessities (washing machines, refriaerators.
ovens).And packaging containersetc.
The company has excellent equipment configuration and strong technical force.It can produce galvanized steel sheets of various specifications ranging from 0.10 to 1.20x700~1250 xC.The ultra-thin large zinc galvanized sheets produced by 0.10~0.151000xC are at the international ad-vanced level. The domestic gap has an incomparable advantage
