This 3-1/2" x 0.250" Hot Rolled Steel Square Tube is a versatile structural section manufactured to ASTM A500 Grade B standards. It offers a high strength-to-weight ratio with 46,000 PSI yield strength, excellent formability, and superior weldability for reliable fabrication. In stock Los Angeles.
- A500B Carbon Steel Construction
- ASTM A500 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability
Hot rolled steel square tube, often called HSS (Hollow Structural Section), is formed to ASTM A500 Grade B specifications. This process gives it a dark, scaled mill finish and slightly rounded corners. Its carbon steel composition ensures a minimum yield strength of 46,000 PSI, providing robust performance for load-bearing applications while remaining easy to cut, drill, and weld.
As a large-profile tube, this 3-1/2" square section is perfectly suited for constructing heavy-duty frames, structural columns, trailer mainframes, and industrial equipment bases where significant load-bearing capacity and rigidity are critical project requirements. It must be painted or coated for outdoor use.
