Ultra-high-strength
G550 base steel
with a tensile strength of 550MPa, engineered for heavy-duty structural applications requiring superior load-bearing capacity. Triple-layer
ZMA275 coating (Zn-Mg-Al)
delivers exceptional corrosion resistance—3x longer lifespan than standard galvanized steel, ideal for harsh environments like coastal areas or industrial zones. Precision-coated
Aluzinc magnesium alloy surface
ensures brilliant aesthetics with a smooth, spangle-free finish, perfect for architectural cladding, roofing, and premium appliances. Advanced
hot-dip Galvalume process
combines 55% aluminum, 43.4% zinc, and 1.6% silicon for optimal heat reflectivity (up to 75% solar reflectance) and fire resistance. Available in custom widths (600mm–1500mm) and thicknesses (0.3mm–3.0mm), tailored for HVAC systems, agricultural sheds, and automotive panels.
