600 - 1250mm Gi Steel Coil JIS DX51D Galvanized Metal Roll Cold Rolled
DX51D Galvanized Steel Coil Factory 600 - 1250MM Cold Rolled JIS ASTM
Galvanized become important steel anticorrosion method, not only because the zinc can be formed in the steel surface protective layer of dense, but also because of the zinc has the effect of cathodic protection, when the galvanized layer damage, it can still through the cathodic corrosion protection to prevent the iron base.
First, the difference between galvalume sheet and galvanized sheet
1. First of all, from the degree of their coating, galvanized sheets are mainly zinc plated on the coating. The coating of galvanized sheet is not only zinc, but also has an extra aluminum.
2. The surface of the galvanized sheet is all plated with zinc, which has a good protective effect on the material and is not easy to rust. The galvalume sheet, because part of the surface is changed from zinc to aluminum, is prone to oxidation and rust. Therefore, in comparison, the service life of galvanized sheet is longer than that of galvalume sheet.
