0.8mm-6.0mm Pre Painted Galvanized Coil 600MPa-900MPa Tensile Strength
600-900MPa Tensile Strength PPGI Coils - Heavy-Duty Construction Material Supplier
600–900MPa Tensile Strength PPGI Coils are engineered for heavy-duty construction projects requiring extreme structural integrity and long-term durability. Designed to meet ISO 1461, ASTM A653, and AS/NZS 1397 standards, these coils feature a Z275–Z600 galvanized base and 20–40µm high-bond polyester coatings, making them ideal for bridges, high-rise buildings, and industrial facilities. With a tensile strength range of 600–900MPa, they outperform conventional steel in load-bearing applications while reducing material usage by up to 30%.
Key Advantages:
- Unmatched Strength: 600–900MPa tensile strength for seismic-resistant and high-load structures.
- Corrosion Defense: Z600 galvanized coating (600g/m²) + PVDF topcoat for C5-M marine/industrial environments.
- Thickness Versatility: 0.8–6.0mm (±0.05mm tolerance) for beams, columns, and reinforcement plates.
- Fire Resistance: Class A1 non-combustible certification (EN 13501-1) + 2-hour fire rating (BS 476-22).
- Eco-Efficient: 50% recycled steel content + carbon-neutral production (ISO 14064).
- Global Compliance: Certified for ASTM A123, JIS G3321, and GB/T 12754 heavy construction standards.
