Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support: Designed to provide robust load-bearing capabilities in construction and manufacturing applications, with ASTM A36 and Q345-grade steel ensuring high tensile strength and durability.
  • Versatile Fabrication: Rectangular cross-section enables seamless integration into frames, scaffolding, machinery components, and custom structures due to its ERW (Electric Resistance Welded) construction and ±1% precision tolerance.

Key features

  • 1. Enhanced Corrosion Resistance through Galvanized Surface Treatment

    • With galvanized surface treatment, you can ensure long-lasting protection against corrosion in harsh environments. This outperforms non-galvanized alternatives by reducing rust and extending service life*.

  • 2. Precision-Engineered Structural Integrity

    • With ERW (Electric Resistance Welded) technology and ±1% dimensional tolerance, you can achieve precise structural integrity and compatibility with high-precision projects. This outperforms other welding methods by minimizing deformations and ensuring uniformity*.

  • 3. Global Compliance with ASTM A53-2007 Standards

    • Certified to ASTM A53-2007 and GB standards, you can meet rigorous quality and safety requirements. This ensures compliance with industry benchmarks, surpassing non-certified steel tubes*.

  • 4. Heavy-Duty Load-Bearing Capacity for Structural Applications

    • Designed with ASTM A36-grade steel, you can support heavy loads in construction and manufacturing projects. This outperforms lighter materials in applications requiring robust durability*.

  • 5. Versatile Customization for Project-Specific Needs

    • With rectangular and square profiles, you can easily customize lengths, drill holes, or bend the tubes to fit specific project requirements. This adaptability surpasses non-modifiable steel alternatives*.

Supplier's note

  1. Technical Breakthroughs:

    • Q345 Grade: Offers 30% higher yield strength than ASTM A36, enabling heavier load capacities.
    • ERW Technology: Achieves seamless joints, reducing failure risks in high-pressure systems.
    • Premium Galvanization: Delivers 40% longer lifespan in corrosive conditions than standard coatings.

  2. Version Selection Guide:

    • Base Model: Suitable for standard construction (e.g., residential framing) where cost-efficiency is prioritized.
    • Advanced Model: Ideal for industrial applications (e.g., machinery supports) needing enhanced durability.
    • Pro Model: Best for extreme environments (e.g., offshore platforms) requiring ultra-high strength and precision.

Example: The Pro version’s Q390 grade and ±0.5% tolerance ensure flawless integration in aerospace structural components, where both strength and dimensional accuracy are critical. Pair its galvanized surface with heavy-duty welding for seamless corrosion protection in marine settings.
