Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support: Designed to provide robust load-bearing capacity in construction and engineering projects, suitable for framing, scaffolding, and support structures.
  • Versatile Fabrication: Hot-rolled steel tubes can be easily cut, welded, bent, or punched to meet specific project requirements, enabling customization for diverse applications.

Key features

  • 1. Material Technology

    • With non-alloy carbon steel ASTM A500 and a hot-rolled black painted finish, ensure superior corrosion resistance and structural durability. Compared to standard carbon steel pipes, this product offers 15% enhanced load-bearing capacity*.

  • 2. Performance Parameters

    • With precise ±10% tolerance and high-strength grades (ASTM A500, Q345), achieve consistent performance under heavy loads. The thick wall design provides 20% greater pressure resistance than thin-walled alternatives*.

  • 3. Scenario Solutions

    • With customizable lengths and processing services (welding, cutting, bending), adapt to diverse construction needs. Ideal for scaffolding and framing, offering 30% faster on-site assembly compared to non-modular tubes*.

  • 4. Certification Standards

    • With CE and ASTM A500 compliance, meet stringent safety and quality standards required for commercial and industrial applications. This certification ensures compatibility with EU and global construction regulations*.

  • 5. Interactive Design

    • With square/rectangular modular sections, easily stack and integrate into structural frameworks. The standardized shape reduces installation errors by 25% compared to irregular profiles*.
