- A36 Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability
A36 hot rolled steel is a low-carbon steel formed at high temperatures, resulting in a scaly, blue-grey mill finish and slightly rounded edges. This process makes it cost-effective and easy to fabricate. Conforming to ASTM A36, it ensures a minimum yield strength of 36,000 PSI, making it a reliable choice for applications where strength and weldability are primary requirements.
As a large-format bar, this 4" width provides a stable foundation for base plates, heavy structural components, equipment mounting, and trailer frames. Its substantial cross-section is ideal for applications requiring high strength and resistance to bending under load in construction and industrial fabrication.
