1.GALVANIZED STEEL COIL DESCRIPTION
Galvalume 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.
Galvalume Steel Coil enjoys both the physical protective feature and durability of Al and the electro
chemical protective property of Zn. And its surface has bright silver color and regular embossed-like
figure, which are highly decorative.
2.GALVANIZED 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.
