0.40x1220 Galvalume Steel Coil Check-up at Factor

Release time:2022-03-14
Last week, 100 tons of 0.40x1220mm galvalume steel coils ordered by our Australian customer were ready for shipment. Before delivering the goods to Tianjin port, we carried out strict inspection on each coil. We checked the size (thickness & width), the surface and zinc coating (which is 80g/㎡)of the coil.These galvalume steel coils will be used to manufacture roofing sheets. The surface of galvalume plate is smooth, has excellent resistance to atmospheric corrosion ability, which is 2 to 6 times higher than that of hot galvanized steel sheet. Since it has similar high temperature corrosion resistance to hot galvanized sheet, and will not have any discoloration and deformation at 315 degrees, it can be used for a long time. Its thermal reflectivity is higher than 75%, which is more than twice the normal galvanized sheet. With good painting and processability, galvalume steel sheet is gradually replacing galvanized sheet and widely used in the world.
