Hot Rolled Steel Rectangular Tube - 4" x 3" x 0.120"
This 4" x 3" x 0.120" wall hot rolled rectangular steel tube is a structural grade product manufactured to ASTM A500 Grade B. It combines 58,000 PSI tensile strength with excellent weldability, making it ideal for robust structural applications like framing and supports. In stock Los Angeles.
- A500B Grade Steel Construction
- ASTM A500 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability
Hot rolled rectangular tubing is a cost-effective structural product manufactured to the ASTM A500 Grade B specification. The hot rolling process gives it excellent forming and welding characteristics with a scaled surface finish. Its combination of strength, toughness, and formability makes it a foundational material for construction, heavy equipment, and industrial fabrication where load-bearing capacity is critical.
As a large-profile tube, this 4" x 3" section provides significant resistance to bending and torsional stress. It is commonly used for heavy structural applications, including building frames, trailer cross-members, heavy equipment bases, and industrial support columns where strength is paramount.
