SGCC Metal Galvanized Sheets Rolled Steel Sheet Zinc Plated Medium Thick 1250mm
Galvanizing refers to a surface treatment technology that plates a layer of zinc on the surface of metals, alloys or other materials to play a role in beauty and rust prevention. The main method used is hot-dip galvanizing.
Zinc is easily soluble in acids and can also be soluble in alkalis, so it is called amphoteric metals. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film is formed on the surface of the zinc. In sulfur dioxide, hydrogen sulfide and marine atmospheres, zinc corrosion resistance is poor, especially in high temperature and high humidity containing organic acids, zinc coating is easy to be corroded. The standard electrode potential of zinc is -0.76V, for the steel matrix, zinc coating is an anodic coating, which is mainly used to prevent corrosion of steel, and its protective performance is very related to the thickness of the coating. Zinc coatings that are passivated, dyed or coated with light protectors can significantly improve their protection and decoration.
