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%.
