ASTM A36 Hot Rolled Carbon Steel Plate Q235 SS400 Mild Steel Sheet 1.5mm-200mm 4x8 Feet for Structural Construction
ASTM A36 Hot Rolled Carbon Steel Plate — Universal Structural Grade
Our ASTM A36 hot rolled carbon steel plate is the most widely utilized structural steel grade in the world, equivalent to Q235B (GB), SS400 (JIS), and S235JR (EN). With excellent weldability, good machinability, and consistent mechanical properties, A36 plates serve as the foundation material for construction, heavy machinery, shipbuilding, and general fabrication. Available from thin 1.5mm sheets to heavy 200mm plates in standard 4x8ft (1219*2438mm) and custom dimensions, we are a preferred supplier to Middle Eastern construction projects, Southeast Asian manufacturers, and African infrastructure developments.
Key Features
- Proven Global Standard: ASTM A36 is recognized worldwide with equivalent grades in all major standards: Q235B (China), SS400 (Japan), S235JR (EU), ensuring seamless substitution across markets
- Excellent Weldability: Low carbon content (≤0.26%) combined with balanced Mn/Si levels provides outstanding weld performance using all standard methods including MIG, TIG, and stick welding
- Wide Thickness Range: Available from 1.5mm thin gauge for light fabrication to 200mm heavy plate for structural columns and base plates
- Consistent Mechanical Properties: Yield strength ≥250 MPa, tensile strength 400-550 MPa, with elongation ≥20% ensuring reliable structural performance
- Multiple Surface Options: Bare, oiled anti-rust, shot blasted (SA2.5), or weldable primer coated to meet your downstream processing requirements
