Hot Dipped Galvalume Gi Secc Zinc Coated Z30-275 Galvanized Steel Coil For Building Material
Is galvanized better than carbon steel?
Galvanizing is a way to protect carbon steel without completely changing its structure. When carbon steel is galvanized, a layer of zinc is spread over its surface. Zinc is much lower on the galvanic scale than carbon steel, which means it's more basic and more likely to give up its electrons than carbon steel.
