- A500B Carbon Steel Construction
- ASTM A500 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability
Hot rolled A500B rectangular steel tubing is a structural product known for its combination of strength, cost-effectiveness, and excellent fabrication characteristics. The hot rolling process results in a material with a rougher, scaled surface finish but outstanding formability and weldability. Conforming to ASTM A500 Grade B, it is designed for load-bearing applications requiring robust performance and high torsional strength.
Classified as a large-size profile, this 4" x 1-1/2" tube is ideal for heavy structural applications. Common uses include building frames, trailer tongues and cross-members, industrial machinery bases, heavy-duty shelving supports, and agricultural equipment frames where significant load-bearing capacity is required.
