Core product matrix and features
We provide a full range of solutions for coated metal sheets certified by global standards, covering cold-rolled substrates, hot-dip galvanized (GI), galvanized aluminum (Galvalume), zinc aluminum magnesium (ZAM) and high-strength roof panels, meeting the diversified needs from infrastructure to high-end manufacturing:
1. Hot-dip galvanized steel coil (GI/SGCC)
Material standards: DX51D+Z80-Z275 (EN 10346), SGCC (JIS G3302)
Coating advantages: zinc layer weight 60-275g/m², salt spray corrosion resistance ≥500 hours (Z275), suitable for general anti-corrosion scenarios.
Typical applications: storage shelves, ventilation ducts, agricultural equipment housings.
2. Galvalume steel coil (AZ150/Galvalume)
Material standards: ASTM A792 AZ150, AS1397 G550
Coating characteristics: 55% aluminum-zinc alloy coating, heat resistance up to 315℃, corrosion resistance 3-6 times that of ordinary galvanizing, and service life of more than 25 years.
Typical applications: industrial plant roofs, color-coated substrates, and automobile exhaust pipes.
3. Zinc-aluminum-magnesium alloy steel coil (ZAM275)
Technological breakthrough: Zn-Al-Mg coating (magnesium content 1.5%-3%), significant self-healing properties, and red rust resistance time of more than 2000 hours.
Implementation standards: JIS G3321 ZAM275, Q/BQB 440-2018
Typical applications: photovoltaic brackets, coastal building enclosures, and cold chain logistics equipment.
4. High-strength roof panels (G550/G350)
Mechanical properties: yield strength 350-550MPa, thickness 0.4-1.2mm, lightweight and wind-resistant (in compliance with AS/NZS 2728).
Surface treatment: PE/PVDF coating can be customized to support decorative effects such as imitation stone grain and wood grain.
