Electro-galvanized substrate: The coating is thin and its corrosion resistance is not as good as that of hot-dip galvanized substrate;

Hot-dip galvanized substrate: a thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface. This galvanized plate has good paint adhesion and weldability.

Hot dipped aluminum zinc substrate:

This product is plated with 55% AL-Zn and has excellent anti-corrosion properties. Its service life is more than four times that of ordinary galvanized steel sheets. It is a replacement product of galvanized sheet.

Features:

(1) It has good durability and corrosion resistance and has a longer lifespan than galvanized steel plates;

(2) It has good heat resistance and is less likely to discolor at high temperatures than galvanized steel plates;

(3) Has good heat reflectivity;

(4) It has processing performance and spraying performance similar to those of galvanized steel sheets;

(5) Has good welding performance.

(6) It has good performance-price ratio, durable performance and extremely competitive price. Therefore, whether it is architectural designers, engineers or manufacturers, galvanized steel sheets have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and roofs.
