Global Market Positioning & Product Advantages

• The global structural steel tube market continues to grow steadily, driven by booming infrastructure investment, urbanization, and industrial upgrading worldwide. In international engineering projects, structural materials are increasingly pursuinghigh strength-to-weight ratio, multi-directional load resistance, easy fabrication, and aesthetic compatibility. Our Square Hollow Section stands out in the competitive global market by solving the pain points of traditional open-section steel (angle steel, channel steel, I-beam) such as uneven stress distribution, poor torsional resistance, and cumbersome installation.
• Compared with ordinary structural steel products, our SHS has core market competitive advantages: uniform four-sided force bearing structure eliminates structural weak points, closed box section maximizes structural rigidity under limited cross-sectional area, significantly reduces overall project weight and construction cost, and integrates structural functionality and architectural aesthetics, perfectly adapting to diversified demands of European, Southeast Asian, Middle Eastern, and American engineering markets.

International Compliance Standards

• Our Square Hollow Section is strictly manufactured and inspected in accordance with global mainstream standards, ensuring full compatibility with international engineering specifications and convenient for global project bidding and acceptance:
  • European Standard: EN 10219, EN 10210 (cold formed/hot finished structural hollow sections)
  • American Standard: ASTM A500, ASTM A618 (structural steel tubing for general construction)
  • British Standard: BS 1387 (structural hollow section for building and engineering)
  • Australian Standard: AS/NZS 1163 (structural steel hollow sections)
  • ISO Standard: ISO 630 (structural steel technical delivery conditions)
• Common steel grades include S235JR, S355J0, A36, A500 Gr.B/C, Q235B, Q355B, covering low-carbon and high-strength structural grades to meet different load-bearing and environmental requirements.

Standard Physical & Mechanical Properties

• All our SHS products undergo strict mechanical performance testing to ensure stable and consistent structural performance. The core physical and mechanical parameters compliant with international standards are as follows:
  • Tensile Strength: 370–510MPa (S235JR); 470–630MPa (S355J0), featuring strong tensile resistance and no easy deformation under axial tension
  • Yield Strength: ≥235MPa (low carbon grade); ≥355MPa (high strength grade), stable yield performance to ensure structural safety under long-term load
  • Elongation: ≥21%, excellent ductility and toughness, effectively resisting impact load and seismic vibration
  • Torsional Stiffness: Symmetrical square cross-section provides uniform multi-directional torsional resistance, far superior to rectangular hollow section (RHS) and open-section steel, effectively avoiding structural torsion and distortion
  • Bending Performance: High moment of inertia and section modulus, uniform stress distribution during bending, no local stress concentration
  • Dimensional Tolerance: Strict compliance with standard tolerances for side length, wall thickness, straightness, and flat end, ensuring precise assembly and seamless welding
  • Surface Performance: Smooth and uniform surface, no cracks, pits, or burrs; customizable hot-dip galvanizing, powder coating, and anti-rust treatment for enhanced corrosion resistance

Product Advantages

• Superior Structural Stability The fully symmetrical square closed structure realizes uniform force bearing in horizontal, vertical, and multi-torsional directions. It effectively disperses dynamic and static loads, reduces structural deformation, and is more stable than angle steel, channel steel, and other open profiles, making it the preferred material for building columns, support frames, and load-bearing structures.
• High Strength-to-Weight Ratio The closed hollow section optimizes cross-sectional mechanical efficiency. Under the same weight, it provides higher rigidity and load-bearing capacity than solid steel; under the same load standard, it reduces overall steel consumption, greatly lowering project transportation, foundation, and construction costs.
• Excellent Processability & Installability The flat four-sided structure simplifies cutting, welding, drilling, and assembly processes. It features high installation efficiency, low construction difficulty, and tight stacking space, saving on-site construction cycle and labor costs, suitable for standardized and modular engineering construction.
• Outstanding Aesthetic & Versatility Neat square appearance with smooth surface meets modern architectural aesthetic requirements, applicable for both hidden structural support and exposed decorative frameworks. It covers lightweight civil construction and heavy industrial equipment support scenarios with ultra-wide application adaptability.
• Customizable Durability With optional hot-dip galvanizing, anti-rust paint, and polymer coating treatments, the product achieves excellent oxidation and corrosion resistance, adapting to harsh environments such as coastal high humidity, high salt spray, and outdoor open-air exposure, extending service life significantly.

Application Scenarios

• Relying on standard compliance and stable performance, our SHS products are exported to Europe, Southeast Asia, the Middle East, Africa, and America, widely used in: building steel structures, factory workshop frames, bridge auxiliary supports, guardrail engineering, mechanical equipment bases, container frameworks, architectural decoration engineering, and municipal infrastructure projects.
