Galvalume Steel Coils

1 - Galvalume Steel Coil Overview

Resist rust, fire, and harsh environmental exposure with Galvalume Steel Coils from ZZC.

How It's Made? Galvalume Steel Coils use high-quality cold-rolled or hot-rolled steel strips as base material, coated with aluminum-zinc alloy layer (usually 55% aluminum, 43.5% zinc, 1.5% silicon) through hot-dip coating process.

The alloy layer forms a metallurgical bond with the base material, combining the corrosion resistance of aluminum and the sacrificial anode protection of zinc, making it the preferred high-performance anti-corrosion steel.

Galvalume steel is produced by coating carbon steel with an aluminum–zinc alloy through a continuous hot-dip process.

This coating combines the superior corrosion resistance and high-temperature performance of aluminum with the excellent formability and sacrificial (galvanic) protection of zinc, resulting in long-lasting durability across demanding applications.

2 - Core Advantages of Galvalume Steel Coils

Four core advantages lead high-end anti-corrosion:

① Super corrosion resistance: The alloy layer forms a dense oxide film, salt spray and moisture resistant, service life is 2-3 times that of ordinary galvanized coils;

② High temperature resistance: Can withstand temperatures above 300℃, suitable for high-temperature working conditions and outdoor exposure environments;

③ Excellent decorativeness: The surface shows a unique silver-gray metallic luster with uniform texture, no need for additional painting;

④ Good processability: Strong coating adhesion, can achieve complex processing such as cutting, bending, stamping and welding, not easy to fall off.
