Many people are confused about galvanized sheet and galvalume sheet, so what is the difference between the two, let me briefly introduce it for everyone:
A layer of zinc material is distributed on the surface of the galvanized sheet evenly, which protects the anode of the base material.The surface coating of the aluminized zinc sheet is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. At the microscopic level, the surface of the aluminized zinc coating is a honeycomb structure, and the "honeycomb" composed of aluminum contains zinc.
The surface of the Galvalume Steel sheet is more beautiful than that of the galvanized sheet. At the same time, the price of the galvanized sheet is more expensive than that of the galvanized sheet, and the price of the small zinc flower is more expensive than that of the large zinc flower.
In cities where the air is humid and rainy, once a certain point of the galvanized sheet is rusted, if the measures are not taken in time, the rusted area will become larger and larger, and finally the entire board surface; even if the galvanized sheet is rusted at a certain point, Will spread.
These are the three differences between galvanized sheet and galvalume sheet.
