This 6" x 6" square tube with a 0.375" wall is manufactured from A500 Grade B hot rolled steel. As a hollow structural section (HSS), it meets ASTM A500 standards, offering a 58,000 PSI tensile strength and a high strength-to-weight ratio for demanding structural projects. In stock Los Angeles.
- A500 Grade B Steel Construction
- ASTM A500 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability
A500 Grade B steel square tube is a hot rolled, welded structural product known for its durability and cost-effectiveness. Formed to meet ASTM A500 specifications, it provides a minimum yield strength of 46,000 PSI, making it a reliable choice for load-bearing structures. Its composition ensures excellent formability and weldability using standard fabrication techniques, though the surface requires cleaning before painting.
As a large-profile tube, this 6-inch section excels in heavy-duty applications where maximum strength and rigidity are critical. It is commonly used for structural columns in buildings, main support frames for industrial machinery, heavy-duty trailer frames, and large-scale architectural supports where load capacity is the primary concern.
