- A500 Grade B Steel Construction
- ASTM A500 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability & Formability
A500 Grade B Hot Rolled Steel Square Tube is a structural grade carbon steel product with a minimum yield strength of 46,000 PSI. Formed at high temperatures, it has a dark, scaled surface and slightly rounded corners. This economical manufacturing process makes it a foundational material for construction and industrial fabrication, offering excellent weldability using common methods and good formability for creating robust structures.
As a large profile, heavy-wall tube, this 4" x 0.375" size excels in applications requiring significant load-bearing capacity. It is commonly used for structural columns, heavy equipment frames, trailer main frames, and industrial supports where strength and rigidity are the primary design requirements over aesthetic finish or tight tolerances.
