AZ100 DX51D Galvalume Steel Coil for Roofing Panels and Industrial Building Applications

AZ100 DX51D Galvalume Steel Coil for Roofing Panels and Industrial Building Applications

１．Product Overview

AZ100 DX51D Galvalume Steel Coil is a hot-dip aluminum-zinc coated steel product designed for roofing, wall cladding, appliance manufacturing, and industrial fabrication. The aluminum-zinc alloy coating combines the barrier protection of aluminum with the sacrificial protection of zinc, providing long-term corrosion resistance in outdoor and industrial environments.

Manufactured according to ASTM A792, JIS G3321, and EN 10346 standards, this galvalume steel coil is widely used for metal roofing systems, building panels, garage doors, ventilation equipment, and industrial enclosures where durability and weather resistance are critical.

２．Technical Solution

The steel substrate is continuously coated with an aluminum-zinc alloy layer through a hot-dip process. The AZ100 coating creates a protective surface that helps reduce corrosion caused by moisture, temperature fluctuations, and atmospheric exposure.

The DX51D base steel offers good forming performance for roll forming, bending, profiling, and fabrication processes. Passivated surface treatment improves storage stability and minimizes oxidation during transportation and processing.
