SS400 Carbon Steel Coil is a common, versatile hot-rolled steel material (JIS G3101 standard) known for good weldability, formability, and strength (min. 400 MPa tensile), used widely in construction, shipbuilding, vehicles, and general manufacturing for structural parts, pipes, and machinery components, offering a cost-effective balance of mechanical properties for various industrial applications.

Grade System: Q235 refers to its yield strength (235 MPa), with sub-grades (A, B, C, D) indicating decreasing sulfur/phosphorus content for better quality (e.g., Q235D is the cleanest).
Mechanical Properties: Offers good tensile strength (370-500 MPa), elongation, and machinability, making it easy to form and weld.
Physical Properties: Density ~7.85 g/cm³, elastic modulus ~200 GPa.
Forms: Available as Hot Rolled (HRC) or Cold Rolled (CRC) coils, often processed into sheets or strips.

SPCD Cold Rolled Steel Coil is a low-carbon, deep-drawing quality steel grade defined by JIS G3141, engineered for superior formability and surface finish. Optimized for stamping, deep drawing, and complex shaping, it exhibits excellent elongation and minimal springback, making it ideal for automotive panels, electronic enclosures, and precision components. Its smooth, bright surface and uniform thickness ensure high-quality finishes in manufacturing. SPCD’s weldability, machinability, and corrosion resistance (when coated) balance performance and cost-efficiency for high-volume industrial applications.

ST12–ST16 Cold Rolled Coils are low-carbon, deep-drawing quality steels conforming to DIN 1623 standards (or equivalent), designed for high formability applications. Grades progress from ST12 (general forming) to ST16 (ultra-deep drawing), with enhanced elongation and reduced r-value for complex shaping. Renowned for their clean surface, precise thickness control, and consistent mechanical properties, they excel in automotive parts, appliances, and enclosures. Their weldability, compatibility with surface treatments, and cost-efficiency make them a staple for mass-produced, intricately shaped metal components.

DC01–DC07 Cold Rolled Steel Coils are low-carbon, deep-drawing quality steels compliant with EN 10130 standards, offering tailored mechanical properties for forming applications. Grades range from DC01 (basic formability) to DC07 (ultra-deep drawing), with increasing ductility and reduced yield strength. Renowned for their smooth surface finish, uniform thickness, and consistent elongation, they are ideal for automotive body panels, household appliances, and industrial stampings. Their adaptability to complex shaping processes, combined with corrosion resistance via coating, ensures reliability in high-volume, precision manufacturing.

A1008 Cold Rolled Steel Coil is a low-carbon, cold-rolled steel grade conforming to ASTM A1008 standards, renowned for its exceptional surface quality, dimensional consistency, and formability. Tailored for deep drawing, stamping, and bending applications, it is widely used in automotive panels, appliances, and metal enclosures. Its fine grain structure and uniform mechanical properties ensure minimal springback and excellent weldability, while surface treatments like oiling or phosphating enhance corrosion resistance. Ideal for cost-sensitive, high-volume manufacturing, A1008 balances performance and affordability.
