DX51D G60 Aluzinc Steel Coil ASTM A755M Aluminium Zinc Coated Steel for Roofing and Appliances
DX51D G60 Aluzinc Steel Coil ASTM A755M Aluminium Zinc Coated Steel for Roofing and Appliances
１．Product Overview
DX51D G60 Aluzinc Steel Coil is manufactured with an aluminum-zinc alloy coating that provides excellent corrosion resistance, heat reflectivity, and long-term durability. Produced according to ASTM A755M and JIS G3312 standards, the product is widely used in construction, household appliances, machinery, and roofing systems.
The combination of a high-quality steel substrate and Aluzinc coating helps extend service life in outdoor and industrial environments while maintaining good formability and processing performance.
２．Technical Solution
The steel substrate is coated through a continuous hot-dip process using an aluminum-zinc alloy layer. This coating combines the corrosion protection of zinc with the barrier protection and heat resistance of aluminum.
The passivated surface treatment improves storage performance and reduces the risk of white rust during transportation and handling.
