Galvalume Steel Coil AZ50 – 55% Al-Zn Coated Steel for Roofing and Wall Panels

Oct 23, 2025

Products Description

 

Hot-dip aluminum-zinc plated steel plate is also called aluminum-zinc plated plate, aluminum-zinc plated natural color plate, aluminum-zinc plated fingerprint resistant plate and aluminum-zinc plated light plate. As the surface coating of the plate is an alloy composed of aluminum, zinc and other trace elements, it has outstanding corrosion resistance and gradually replaces galvanized plate. Aluminum-zinc plated plate is mainly used for steel structure roof, wall surface, switch cabinet body and household appliance board.

 

The mixed structure of hot dip aluminum zinc silicon coating has its unique advantages in corrosion resistance. When the aluminum-zinc plate is used, the zinc-aluminum eutectic in the aluminum-rich phase skeleton is first corroded, which has a good protective effect on the incision as pure zinc. The corroded product is not as easy to fall off as the galvanized plate, but is just stored in the aluminum-rich phase skeleton gap, which can prevent further corrosion of the coating to a certain extent.
