1.Hot Dip Zincalume Steel Coil description
Hot Dip Zincalume Steel Coil is a kind of coated steel. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. Hot Dip Zincalume Steel Coil enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative.
2.Hot Dip Zincalume Steel Coil technical process
After cleaning and acid pickling, the steel coil is submerged in melted Aluzinc, a chemical reaction permanently bonds the aluzinc. The zinc actually permanently becomes a part of it and the successive layers are a mixture of aluzinc and iron.
