High-Precision Structural Square Tubes (SHS) for Construction & Fabrication
Our factory specializes in manufacturing premium square tubes designed for maximum structural efficiency and aesthetic appeal. These Square Hollow Sections (SHS) are cold-formed or hot-rolled to ensure uniform wall thickness and exceptional torsional rigidity. Engineered to meet international standards such as ASTM A500, EN 10219, and JIS G3466, our square tubing is available in various grades, including carbon steel and galvanized finishes. Whether you are building heavy-duty industrial frames, architectural landmarks, or modern furniture, our square tubes provide the perfect combination of strength, weldability, and precision for any project.

Industrial-Grade Square Hollow Sections: The Ultimate Choice for Strength and Symmetry
The Advantage of Square Tubing
Square tube, often referred to in engineering as SHS (Square Hollow Section), is a hollow steel profile with a square cross-section. Its symmetrical shape offers a significant advantage in structural design, providing equal strength in two or more planes. This makes square tubes far more resistant to lateral loads and twisting compared to traditional I-beams or channels. At our facility, we combine high-grade raw materials with advanced rolling technology to produce tubes that are as reliable as they are versatile.
Technical Specifications & Standards
We maintain a strict quality management system to ensure our square tubes comply with global engineering benchmarks:
Structural Standards: ASTM A500 Grade A/B/C, EN 10219 (Cold-formed), EN 10210 (Hot-finished).
Material Grades: Q235B, Q355B (S355JR), ASTM A36, SS400.
Surface Treatment Options: * Black/Bare: For projects requiring further welding and painting.
Pre-Galvanized: Ideal for cost-effective indoor/outdoor protection.
Hot-Dipped Galvanized (HDG): Maximum corrosion resistance for harsh industrial or coastal environments.
Oiled/Varnished: Temporary protection against rust during transit.
Key Performance Benefits
Excellent Strength-to-Weight Ratio: The hollow center reduces weight while the flat surfaces provide high structural integrity, lowering overall material and foundation costs.
Ease of Fabrication: The flat sides of the square tube make it exceptionally easy to join, weld, and bolt to other surfaces, resulting in faster assembly times.
Uniformity and Precision: Our automated production lines ensure tight dimensional tolerances and consistent corner radii, which is critical for CNC machining and automated welding.
Aesthetic Appeal: With clean lines and a smooth finish, square tubes are frequently used in “exposed” steel architecture and high-end furniture design.
Dimensional Range

Common Applications
Our Square Tubes are utilized across a vast array of industries:
Architecture: Support columns, roof trusses, and decorative building facades.
Infrastructure: Pedestrian bridges, highway guardrails, and signage supports.
Agriculture: Greenhouse frames, fencing systems, and livestock gates.
Machinery: Heavy equipment chassis, conveyor frames, and trailer beds.
Commercial: High-quality shelving, racking systems, and modern steel furniture.
Factory-Direct Quality & Logistics
As a dedicated square tube manufacturer, we provide a Mill Test Certificate (MTC) with every shipment to verify chemical composition and mechanical properties. We offer additional value-added services, including precision cutting, deburring, and hole punching. Our experienced logistics team ensures that every bundle is securely strapped and protected for international shipping, ensuring your order arrives on-site in perfect condition.
