What is DX51D z?
DX51D+Z275 refers to hot dip galvanising with a 275g/㎡ double-sided layer of Zinc. The purpose of hot dip galvanising is to prevent the steel substrate from rusting. Using 80g/㎡ of Zinc is quite common in a lot of galvanised products, but using 275g/㎡ of Zinc provides a premium galvanised product.
How thick is AZ150 coating?
The layer of Alu-zinc has a thickness of approx. 20 μm (0.020 mm) per side for AZ150. The corrosive speed, i.e. how much of the coating that disappears each year, is a maximum of 0.2 μm in a normal environment (C2) in which Alu-zinc is freely exposed
What is the difference between AZ100 and AZ150?
Compared to ZINCALUME® AZ150 steel, a Zinc Aluminium coating of AZ100 will reduce the life of the product by 50% (or half the life).
What is the spec of DX51D?
DX51D steel products are produced in coils 0.4-1.6 mm thick and 950-1250 mm wide. The inner diameter of the coil is 600±20 mm and outer diameter is up to 1300 mm. Coil weight is up to 8 tons. Coils are supplied with cut edges (mill edges are also possible).
What are the properties of DX51D AZ150?
Dx51d AZ150 is a hot-dip aluminum-zinc steel alloy with a coating of 55 percent aluminum, 1.6 percent silicon, and 43.4 percent zinc. The chemical composition of Dx51d AZ150 offers superior resistance to heat and corrosion, with high thermal reflectivity and conductivity.
