Hot Sale Q235 A36 Hot Dip Galvanized ERW Square&Rectangular Hollow Steel Pipe 50*50 for Structure JIS/KS/BIS Cutting Welding

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support: Designed for construction and structural applications, providing high strength and durability with Q235/A36 steel, ideal for load-bearing frameworks and building skeletons.
  • Versatile Fabrication: ERW (Electric Resistance Welded) technique ensures seamless joints, enabling easy bending, cutting, and welding for diverse project needs.

Key features

  • 1. Material Technology: Corrosion-Resistant Hot Dip Galvanized Steel

    • With Q235/A36-grade steel and hot dip galvanization, ensure long-lasting durability and resistance to corrosion in harsh outdoor or industrial environments. The non-alloy steel provides a cost-effective yet robust foundation for structural applications.

  • 2. Performance Parameters: Thick-Wall ERW Construction for Structural Integrity

    • Engineered with thick walls and ERW (Electric Resistance Welded) technology, these pipes deliver exceptional load-bearing capacity and precision tolerance (±5%). This makes them ideal for demanding applications requiring high strength and dimensional accuracy.

  • 3. Scenario Solutions: Versatile for Construction and Structural Frameworks

    • Designed with a square/rectangular cross-section, these pipes offer superior stability and adaptability in construction projects. Their compatibility with cutting, bending, and welding services enables customization for diverse building frameworks, scaffolding, and industrial structures.

  • 4. Certification Standards: RoHS Compliance and Global Standards Adherence

    • Certified to RoHS standards and manufactured to meet ASTM, GB, and JIS specifications, these pipes ensure environmental safety and international regulatory compliance. This makes them a trusted choice for eco-conscious and export-focused projects.

  • 5. Customization Flexibility: Tailored to Project Requirements

    • With processing services like punching, decoiling, and welding, these pipes can be customized to fit specific project needs. Whether for precise cuts or complex bends, this adaptability reduces downtime and enhances design possibilities.

Supplier's note

  1. Technical Breakthroughs:

    • ERW Welding: Seamless joints reduce failure risks in high-stress applications.
    • Dual Coatings: Hot dip galvanization + black paint provide 60% longer lifespan than uncoated steel.
    • Custom Wall Thickness: Up to 8mm walls handle 40% heavier loads than standard pipes.

  2. Version Selection Guide:

    • Base Model: Ideal for standard residential construction where cost-efficiency is prioritized.
    • Advanced Model: Best for mid-scale industrial projects needing enhanced corrosion resistance (e.g., chemical storage).
    • Pro Model: Required for heavy machinery supports or offshore structures demanding triple the industry-standard load capacity.

*Pro Model’s 4.2mm walls exceed ASTM A500 Grade B requirements, enabling safe use in seismic zones.
