Key Features

  1. Material Grades & Standards

    • Q235/Q235B: Chinese GB-standard carbon structural steel with a minimum yield strength of 235 MPa, offering good weldability and plasticity.

    • Q355: Higher-strength Chinese GB-grade steel (355 MPa yield strength) for heavy-duty applications.

    • S235/S355JR: European EN-standard grades (S235JR: 235 MPa yield strength; S355JR: 355 MPa yield strength with improved impact toughness at room temperature).

  2. Structural Performance

    • High load-bearing capacity and resistance to bending/deformation.

    • Excellent weldability and machinability, compatible with cutting, drilling, and bolting.

  3. Durability

    • Hot-rolled surface with optional treatments (e.g., galvanizing) to enhance corrosion resistance for harsh environments.

  4. Compliance & Consistency

    • Meets international standards (GB, EN, ASTM) for chemical composition, mechanical properties, and dimensional tolerances.

  5. Cost-Efficiency

    • Bulk stock availability in various sizes (leg lengths: 20–200 mm; thickness: 3–20 mm) ensures quick delivery and budget-friendly pricing.

Applications

  • Building Construction: Structural frameworks, roof trusses, beams, and columns.

  • Infrastructure: Bridges, transmission towers, and railway/road guardrails.

  • Machinery & Equipment: Support frames, conveyor systems, and industrial machinery bases.

  • Renewable Energy: Solar panel mounting structures and wind turbine components.

  • Transportation: Truck trailers, shipbuilding, and container reinforcement.

  • General Fabrication: Shelving units, brackets, and decorative metalwork.
