SS400, ASTM A36, St37 Unequal Angle steel for constructicsvfdbsgbgfbgnhg

Unequal angle steel is an L-shaped profile with unequal leg lengths, manufactured through hot-rolling. Made of Q235 carbon structural steel, it complies with GB/T 9788-1988 (Chinese standard for hot-rolled unequal angle steel). Typical specifications like L30×20×3 (long leg 30mm, short leg 20mm, thickness 3mm) make it ideal for construction frames, bridge supports, machinery, and shipbuilding. Unequal Angle steel can be divided into two types: unequal Angle steel with equal thickness and unequal Angle steel with unequal thickness.

    Product Introduction

    Unequal angle steel is an L-shaped profile with unequal leg lengths, manufactured through hot-rolling. Made of Q235 carbon steel, it compliestructural s witipbuilding. Unequal Angle steel can be divided into two types: unequal Angle steel with equal thickness and unequal Angle steel with unequal thickness.

    Production technology

    Hot Rolling: High-quality carbon steel coils are heated and shaped by rolling mills to achieve precise dimensions and mechanical properties.

    Surface Treatment: Pickling removes oxides, followed by galvanizing or painting for enhanced corrosion resistance.

    Cold Bending & Welding (Optional): Custom shapes via cold bending or extended lengths through welding.

    Product advantage

    High Strength: Tensile strength ≤370MPa, ideal for load-bearing structures.

    Corrosion Resistance: Galvanized or painted surfaces enhance outdoor durability.

    Easy to process: Easily cut, welded, or bent for complex designs.

    Cost-Effective: Lower cost than I-beams for light-duty applications.

    Application

    Construction: Roof trusses, transmission towers, warehouse racks.

    Machinery: Equipment brackets, automotive parts.

    Shipbuilding & Bridges: Hull structures, bridge reinforcements.

    Packaging and Shipping

    Packaging:
    Steel-strapped bundles with moisture-proof paper, optional wooden crates/pallets for heavy loads.

    Transportation:
    Sea Freight: Container shipping (FCL/LCL) or bulk carriers (for oversized profiles)
    Air/Land: DDP door-to-door delivery (global arrival within 7-15 days)
    Inter-modal: Hybrid solutions combining sea-air-land for urgent orders & cost optimization

    Q1: How to choose specifications?

    A: Select the edge width and thickness based on the load-bearing requirements. For instance, for light-duty shelves, 30×20×3mm can be chosen, while for heavy-duty Bridges, 100×63×6mm is required.

    Q2: How to choose the anti-corrosion treatment method?

    A: For outdoor use, hot-dip galvanizing is recommended (with strong weather resistance), while for indoor use, painting is an option (with low cost).

    Q3: What are the advantages and disadvantages compared with I-beams?

    A: Angle steel has a low cost and flexible connection, but its torsional resistance is relatively weak. I-beams are suitable for large-span load-bearing.

    Q4: Can you provide me with samples for inspection?

    A: Yes, we will provide samples for free, but the shipping cost will be paid by the customer's account.

    Q5: Where are you? Can I come see you?

    A: We are in Tianjin, China. Of course you are welcome to visit our factory anytime.
