DX51D AZ150 ASTM A792 Galvalume Steel Coil for Roofing, Cladding and Industrial Applications

DX51D AZ150 ASTM A792 Galvalume Steel Coil for Roofing, Cladding and Industrial Applications

１．Product Overview

DX51D AZ150 Galvalume Steel Coil is produced according to ASTM A792, JIS G3321, and related international standards. The product combines a high-strength steel substrate with an aluminum-zinc alloy coating that provides superior corrosion resistance and long-term durability.

The AZ150 coating is widely used in roofing systems, wall cladding, household appliances, transportation equipment, and industrial manufacturing applications where weather resistance and service life are critical.

２．Technical Solution

The steel substrate is continuously coated with an aluminum-zinc alloy layer through a hot-dip process. The coating combines the barrier protection of aluminum with the sacrificial protection of zinc to improve corrosion resistance compared with conventional galvanized steel.

Optional anti-finger treatment, chromating, and oiling further enhance storage stability, appearance quality, and fabrication performance.

３．Specifications

４．Application
