This 4" x 4" Hot Rolled Steel Square Tube is manufactured to ASTM A500 Grade B specifications, ensuring a minimum yield strength of 46,000 PSI for structural integrity. Its excellent weldability and high strength-to-weight ratio make it ideal for heavy fabrication projects. In stock Los Angeles.
- A500 Grade B Steel Construction
- ASTM A500 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability & Formability
A500 Grade B Hot Rolled Steel Square Tube, also known as Hollow Structural Section (HSS), is a carbon steel product formed at elevated temperatures. This process results in a material with good formability, excellent weldability, and robust structural properties per ASTM A500. The scaled surface finish and slightly rounded corners are characteristic of the hot rolling process, making it a cost-effective choice for applications where aesthetics are secondary to strength.
As a large-profile tube, this 4" x 4" size provides substantial load-bearing capacity and rigidity. It is frequently specified for structural columns in buildings, heavy-duty equipment frames, main supports for industrial racking, and robust trailer frames where strength and durability are critical design requirements.
