Square and Rectangular Hollow Section Metalon Galvanizado 20x20

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support: High-strength square/rectangular hollow sections designed for load-bearing applications in construction and infrastructure.
  • Corrosion Resistance: Galvanized surface treatment ensures durability in harsh outdoor and industrial environments.
  • Precision Engineering: ERW (Electric Resistance Welded) technique and tight tolerances (1%, ±1%) guarantee structural integrity and seamless integration into complex systems.

Key features

  • 1. Corrosion-Resistant Galvanized Surface

    • With a galvanized surface, you can achieve enhanced corrosion resistance in harsh environments compared to non-galvanized steel pipes*. The zinc coating protects against rust and oxidation, extending the product’s lifespan in outdoor or industrial settings.

  • 2. Structural Stability via Square/Rectangular Design

    • With a square/rectangular cross-section, you can ensure precise alignment and structural stability in construction projects, unlike round pipes that may shift during installation*. The uniform shape simplifies integration into frameworks and load-bearing systems.

  • 3. High-Strength Performance with ERW Technology

    • With thick walls, ERW (Electric Resistance Welded) technology, and tight tolerances (±1%), you can handle heavy loads and ensure seamless structural integrity, outperforming thin-walled alternatives*. Grades like Q195-Q345 and A53 meet rigorous strength requirements for demanding applications.

  • 4. Customizable Solutions for Diverse Projects

    • With processing services like cutting, bending, and welding, you can adapt these tubes to specific project needs, offering greater flexibility than standard pipes*. Ideal for construction, furniture, or industrial frameworks requiring tailored dimensions.

  • 5. Compliance with Industry Certifications

    • With API and BS certifications, you can meet strict safety and quality standards for commercial and regulated environments*, ensuring reliability in applications like infrastructure and heavy machinery.

Supplier's note

  1. Technical Breakthroughs:

    • Galvanized Coating: Triple the corrosion resistance of uncoated steel, extending service life in marine or industrial settings.
    • Q345+ Grade Steel: 30% higher tensile strength than Q235, enabling use in high-stress applications like bridge frameworks.
    • Precision Tolerance: ±0.3% tolerance in Pro models ensures compatibility with automated manufacturing systems.

  2. Version Selection Guidance:

    • Base Model: Ideal for general construction (e.g., residential framing) where cost-efficiency is prioritized.
    • Advanced Model: Suitable for heavy industrial projects (e.g., warehouse racking) requiring enhanced durability.
    • Pro Model: Recommended for extreme environments (e.g., offshore platforms) where ultra-thick walls and precision are critical.

Example: The Pro version’s 40% thicker walls, paired with Q345+ steel, enable safe handling of 50-ton loads in seismic zones. Its ±0.3% tolerance ensures flawless alignment in automated assembly lines.
