A500 Grade B Hot Rolled Steel Square Tube - 3-1/2" x 0.120"

This 3-1/2" x 3-1/2" Hot Rolled Steel Square Tube, with a 0.120" wall, meets ASTM A500 Grade B specifications for structural applications. It provides a minimum yield strength of 46,000 PSI and excellent weldability, making it a reliable choice for robust structural fabrication projects. In stock Los Angeles.

A500 Grade B Steel Construction
ASTM A500 Certified
58,000 PSI Tensile Strength
Excellent Weldability

A500 Grade B hot rolled square tube is a carbon steel structural section formed at elevated temperatures, resulting in a scaled surface finish and slightly rounded corners. It complies with ASTM A500, ensuring a minimum yield strength of 46,000 PSI. Its composition provides excellent formability and weldability, making it a foundational material for heavy-duty structural applications requiring significant load-bearing capacity and impact resistance.

As a large-profile tube, this 3-1/2" size is purpose-built for heavy structural applications. Common uses include building frames, industrial supports, heavy equipment bases, and main structural members in trailer manufacturing, where maximum rigidity and strength are paramount. Its substantial cross-section provides excellent resistance to bending and torsional forces, ensuring structural integrity in demanding environments.

Finish Options

This product comes standard with a hot rolled mill finish, characterized by a dark, scaled surface. This surface must be prepared by grinding, sandblasting, or chemical cleaning before coating. For long-term corrosion resistance, especially in outdoor applications, it should be painted, powder-coated, or galvanized. Contact our Los Angeles sales team for custom finish inquiries.
