Factory Wholesale ASTM A36 Ss400 S235jr S275jr C45 A572 A283 St37 Cold Hot Rolled High Low Mild Carbon Steel Iron Plate Sheet Supplier Price for Building Mate

Our steel plate products include high-strength low-alloy steel Plate, carbon structural steel plate, alloy structural steel plate, boiler and pressure vessel steel plate, bridge steel plate, shipbuilding and marine oil platform steel plate, pipe steel plate, high strength and high toughness steel plate, mold plate, corrosion-resistant plate, and composite plate with 12 major series.

Carbon steel plates are available in different grades depending on the carbon content and strength. As the content of Carbon increases, the steel plate hardness increases.

• Low carbon steel plate: 0.06% to 0.25% carbon (Mild steel).
• Medium carbon steel plate: 0.25% to 0.55% carbon.
• High carbon steel plate: 0.55% to 1.0% carbon (Hard steel).

Manufacturing Technique: We offer cutting of large steel plates to your requirements, milling and grinding for a bright surface, hole punching, and welding based on technical drawings. For thicknesses under 30mm, we use laser cutting; for over 30mm, we primarily use OXY-cut and flame cutting.

Quality control is strictly managed for every steel plate. Each plate is assigned an identification label. We verify chemical components and physical properties, providing a material test certificate (MTC). Dimensional inspections are performed and shared with customers to ensure all requirements are met.

We accept third-party inspections (SGS, BV, etc.) and hold ISO9001, ISO18001, and CE certifications.

With convenient access to major international ports, we specialize in exporting high-quality steel products worldwide. As a professional trading entity, we supply carbon steel plates, coils, pipes, galvanized products, and structural steel such as H-beams and channels.
