Sizes 3 X 3 Inch Square Hollow Section GI Steel Tubing for Sale

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support: Designed for building frameworks, load-bearing structures, and industrial applications. The square hollow section provides high strength and stability.
  • Corrosion Resistance: Galvanized (GI) coating ensures durability in harsh environments, suitable for outdoor or high-moisture settings.

Key features

  • 1. Material Technology

    • With a galvanized steel (GI) coating and hot-rolled finish, you can achieve superior corrosion resistance and durability in harsh environments like coastal or industrial zones. ~30% thicker walls than standard pipes* ensure long-term structural integrity.

  • 2. Customization Flexibility

    • With versatile processing services (punching, cutting, welding), you can easily customize the tubing to precise project specifications, reducing post-purchase modifications and waste.

  • 3. Precision Performance

    • With a thickness range of 0.6–20mm and precision tolerances as tight as ±1%, you can meet diverse structural demands while ensuring seamless integration with other materials.

  • 4. Scenario Solutions

    • Designed for structural and building applications, these tubes provide robust support for both residential frameworks and commercial high-load projects, enhancing durability and safety in demanding environments.

  • 5. Certification Standards

    • Backed by CPR certification for construction safety and RoHS compliance for eco-friendly materials, you can meet stringent industry regulations and environmental standards.

Supplier's note

  1. Technical Breakthroughs:

    • Enhanced Galvanization: The Pro Model’s 30% thicker zinc coating triples corrosion resistance, ideal for marine or chemical environments.
    • Precision Tolerances: ±1% tolerance ensures seamless integration in high-precision machinery.
    • ERW Welding: Seamless joints reduce failure risks in high-stress applications.

  2. Version Selection Guide:

    • Base Model: Suitable for residential or light commercial projects requiring cost-effective solutions (e.g., fencing).
    • Advanced Model: Optimized for mid-scale construction (e.g., bridges, temporary scaffolding) with improved load and corrosion resistance.
    • Pro Model: Designed for heavy industrial use (e.g., offshore platforms, mining equipment) where extreme durability and precision are critical.

With the Pro Model’s 30% thicker zinc coating, you can ensure safe handling of corrosive chemicals in industrial settings. Pair its ±1% tolerance with ERW welding for seamless, high-strength assemblies in demanding environments.
