The galvalume & aluzinc steel sheet in coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43.4% zinc and 1.6% silicon at 600 °C.
It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc steel coil.
1.Advanced equipment, such as Germany Miebach auto laser welder, five-stand tandem cold rolled mill;
2.Complete Supply chain, from Pickling steel coils, to CRFH, GI, GL, PPGI/PPGL;
3.Short delivery time;
4.Good quality with reasonable price.
Strong corrosion resistance, 3 times that of galvanized steel sheet.
The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same,
the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.
