Hot Rolled Steel Rectangular Tube - 4 Inch X 3 Inch X 0.25
This 4" x 3" x 0.250" hot rolled rectangular steel tube is a structural grade product conforming to ASTM A500 Grade B. It offers a high strength-to-weight ratio with 58,000 PSI tensile strength, making it ideal for robust structural frames, trailer beds, and heavy equipment supports. In stock Los Angeles.
- A500B Carbon Steel Construction
- ASTM A500 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability and Formability
Hot rolled rectangular steel tubing is a structural product manufactured to the ASTM A500 Grade B specification. The hot rolling process delivers excellent forming and welding characteristics with high strength and durability, though with a rougher, scaled surface finish. Its combination of strength, weldability, and cost-effectiveness makes it a foundational material for construction, fabrication, and industrial manufacturing projects requiring robust performance and load-bearing capacity.
As a large-profile tube, this 4" x 3" dimension provides exceptional resistance to bending and torsional stress. It is ideal for heavy structural applications including building frames, industrial supports, trailer beds, and machine bases where maximum strength and rigidity are primary requirements. The rectangular shape offers superior compression and torsional strength compared to open profiles.
