Product Overview
Our DX51D/DX52D Galvalume steel coils are manufactured in compliance with ASTM, JIS, and EN standards, using cold-rolled base steel with hot-dip 55% Al-Zn coating (Aluminum-Zinc alloy). Coating weights range from AZ30 to AZ150 g/m², offering superior corrosion resistance, thermal stability up to 300°C, and a typical lifespan of 20–50 years—significantly outperforming regular galvanized steel.
Ideal for applications requiring enhanced durability and surface aesthetics in construction, roofing, fencing, containers, and industrial fabrication.
