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.
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.
