Galvalume Steel Coil

Galvalume steel coil is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.

◉ Product Details

Aluminum-Zinc Coated Coil Product Overview

Aluminum-zinc coated coils are a type of steel surface treatment product that combines the advantages of both aluminum and zinc. They are commonly used in the construction, home appliance, and automotive industries. Through the hot-dip aluminum-zinc coating process, this material offers excellent corrosion resistance and superior formability.


Features

Superior Corrosion Resistance: The combination of aluminum’s oxidation resistance and zinc’s sacrificial protection gives aluminum-zinc coated coils outstanding corrosion resistance.

Excellent Coating Adhesion: The smooth surface facilitates the adhesion of paints and other treatments.

High Strength, Lightweight: At comparable strength levels, aluminum-zinc coated coils are lighter than traditional galvanized coils.

Environmentally Friendly: Effectively reduces the use of heavy metals and harmful substances.
