1.Aluzinc Coated Galvanized Steel Sheet description
Aluzinc Coated Galvanized Steel Sheet 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. Aluzinc Coated Galvanized Steel
Sheet 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.Aluzinc Coated Galvanized Steel Sheet 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.
3.Aluzinc Coated Galvanized Steel Sheet main usage scope:
1)Architecture roofs and outside walls of civilian and industrial buildings, garage doors, fencings and window blinds
2) Appliances industry outer clad sheets for washing machine, refrigerator, television, air conditioner and ventilation system,
