Hollow Iron Cross Twisted Square Bar

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support & Precision: Designed as a hollow iron cross-twisted square bar with diameters of 5mm or 6mm, engineered to provide high strength-to-weight ratios for load-bearing applications.
  • Material Compliance: Manufactured from Q235 steel, meeting international standards (GB/ASTM), ensuring durability and corrosion resistance for reliable performance.

Key features

  • 1. Material Technology: Corrosion-Resistant Q235 Steel

    • With Q235 steel construction, ensure robust structural integrity and corrosion resistance for long-term durability in industrial and construction environments. This material balances strength and cost-effectiveness, making it ideal for demanding applications.

  • 2. Performance Parameters: Precise Dimensions for Efficient Use

    • With a 12m length and 5-6mm diameter options, reduce material waste and installation time compared to shorter segments*. The uniform thickness and precise measurements (aligned with GB/ASTM standards) ensure seamless compatibility with machinery and frameworks.

  • 3. Scenario Solutions: Twisted Square Design for Stability

    • With a twisted square cross-section, enhance stability in frameworks and reduce slippage during assembly. This shape optimizes load distribution, making it perfect for structural reinforcement, scaffolding, or decorative applications.

  • 4. Certification Standards: Dual Compliance for Global Use

    • With dual GB (China) and ASTM (international) certifications, meet strict quality and safety standards for industrial use. This ensures reliability in construction, manufacturing, and engineering projects worldwide.

  • 5. Weight Efficiency: Hollow Core for Cost Savings

    • With a hollow cross-section, achieve weight savings of up to 30% compared to solid bars* without compromising strength. This reduces transportation costs and labor intensity while maintaining structural performance.
