ASTM A588 steel is sorted into Class A, Class B, Class C, and Class K. The ASTM A588 steel specification is based on the standard specification for high-strength low-alloy structural steel with a lower yield point of up to 50ksi for applications requiring high strength and corrosion resistance.

Carbon steel coil is a commonly used metal material with a wide range of applications in many fields. It has good mechanical and processing properties and is widely used in fields such as automobile manufacturing, shipbuilding, construction, and bridges.

A36 is a carbon structural steel coil whose chemical composition and mechanical properties strictly conform to American ASTM standards. Good mechanical properties, welding performance and corrosion resistance are basically why they are widely used in construction, bridges, machinery manufacturing and other fields.

ASTM A283 cold rolled steel coil has low and medium tensile strength. The ASTM A283 steel specification covers four structural quality grades of mild steel, grades A, B, C, and D, for general application.

ASTM A514 steel is available in several grades. And they have the same mechanical properties. ASTM A514 steel coils are conventionally quenched and tempered steel with high yield strength, weldability and toughness. ASTM A514 steel is a special high-strength steel, mainly used as building structural steel.

A572 steel has four different grades: 42, 50, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.

SPCC steel is produced by subjecting hot rolled steel to a cold rolling process, which not only improves its surface finish but also enhances its mechanical properties.

A573/A573M steel has grades including 58, 65 and 70. The coil is suitable for structural grade carbon-manganese-silicon steel in 3 tensile strength ranges. ASTM A573/A573M steel coils are mainly used to improve notch toughness at room temperature.

A633 steel has four grades of A, C, D, and E. The thickness of grade C can reach 4 inches and the thickness of grade E can reach 6 inches. ASTM A633 steel specification is based on the standard specification for standardized high-strength low-alloy structural steel coil, which requires high notch toughness under low temperature conditions.
