Aluminum Alloy Steel Coil JIS G3321 UV-Resistant 1200mm Standard Width


JIS G3321-Certified Aluminum Alloy Steel Coil is engineered for exceptional UV resistance and durability in demanding outdoor environments. Featuring a ​55% aluminum-zinc coating and compliant with ​JIS G3321 standards, this coil is available in a ​1200mm standard width and thicknesses from ​0.3mm to 3.0mm, making it ideal for roofing, automotive, and industrial applications. Its advanced alloy composition ensures long-term corrosion protection, heat reflectivity, and structural reliability, even under prolonged sun exposure.

Key Selling Points:

  • UV & Weather Resistance: Reflects 85% of UV radiation (ASTM G154 tested), preventing coating degradation.
  • Lightweight Strength: 20% lighter than traditional steel, with tensile strength up to ​550 MPa (JIS G3321 Grade SGH340).
  • Longevity: Aluminum-zinc coating outperforms galvanized steel by 3x in salt spray tests (JIS H8501).
  • Eco-Friendly: Fully recyclable and compliant with RoHS and REACH regulations.
  • Customizable: Pre-painted options in RAL colors or anti-fingerprint finishes.
