Structural Steel Square Tube
Square tubes are strong, durable steel sections with equal sides, widely used in construction, machinery, and fabrication. They offer stable support, clean appearance, and meet various size and standard requirements.
What Is Structural Steel Square Tube?
Also known as Square Hollow Section (SHS) in metric contexts, or part of Hollow Structural Section (HSS) family in U.S. standards. Square HSS refers specifically to square-shaped tubing used in structural steel applications.
Typically manufactured via cold-forming and welding processes, though seamless options exist. Common standards include ASTM A500 (most prevalent for structural applications), ASTM A513 (mechanical tubing), and others like ASTM A1085 or A847 for high-strength or weathering steels.

Advantages of Structural Steel Square Tubes
1. High Strength-to-Weight Ratio
The hollow profile provides excellent load-bearing capacity while reducing weight, making it ideal for structures requiring strength without excess mass.
2. Uniform Strength
The symmetrical square shape allows for consistent performance under bending, compression, and torsion loads from multiple directions.
3. Ease of Fabrication
Square tubing is easy to cut, weld, drill, and machine, enabling flexible use in custom projects and mass production.
4. Corrosion Protection Options
Available in stainless steel, galvanized finishes, or with protective coatings to enhance durability in outdoor or corrosive environments.
5. Aesthetic Appeal
The clean lines and geometric profile make square tubing popular in architectural and decorative designs.
Common Applications
Construction: Structural frameworks, columns, and bracing systems
Industrial: Machine frames, conveyors, and material-handling structures
Transportation: Trailer frames, truck racks, and rail systems
Architectural: Handrails, fencing, and modern furniture
Agricultural: Greenhouse frames, storage racks, and livestock pens
Choosing the Right Structural Steel Square Tube
When selecting square tubes, consider:
Load requirements (check section modulus and moment of inertia)
Environment (galvanized or stainless for outdoor or corrosive settings)
Fabrication process (cold-formed for tight tolerances, hot-formed for heavy-duty strength)
Compliance with regional standards (ASTM, EN, JIS, etc.)
Structural steel square tubes offer a unique balance of strength, durability, and design flexibility. Their hollow form reduces weight without sacrificing performance, making them a cost-effective solution for everything from high-rise buildings to custom furniture. Whether you need corrosion resistance, structural integrity, or a modern look, there is a square tube specification to fit your application.
As a leading Rectangular Steel Tubes manufacturer, Huizhe delivers structural excellence. Our hollow rectangular tubes(also known as rectangular hollow sections or RHS) are precision-engineered from premium carbon steel, alloy steel, or stainless steel. Utilizing advanced ERW (Electric Resistance Welding) or cold-forming technology, we guarantee exceptional dimensional accuracy, uniform wall thickness, and superior load-bearing capacity. Ideal for projects demanding maximum rigidity and space efficiency, our tubes offer unbeatable strength-to-weight ratios and seamless weldability. Available as hot-finished or cold-formed variants, Huizhe tubes strictly comply with international standards (ASTM, EN, JIS), ensuring reliability for every project.
