ALUMINIZED STEEL TYPE I & TYPE II

Carbon steel coils are coated according ASTM A463 on both sides with a pure aluminum or an aluminum 5% to 10% silicon alloy. The pure aluminum coated product is called ALUMINIZED TYPE II, and the aluminum-silicon alloy coated one is called as ALUMINIZED TYPE I. 

 

Aluminized sheets have many applications in refineries, the petrochemical industry, gas power plants, oil storage facilities, grain silos, and pipe cladding, automotive industry.
