◉ Product Description

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.
