- A36 Carbon Steel Construction
- ASTM A36 Certified
- 58,000 PSI Tensile Strength
- Excellent Weldability & Formability
A36 hot rolled steel is a low-carbon steel alloy produced via a high-temperature rolling process, resulting in a scaly, blue-grey finish and slightly rounded edges. It complies with ASTM A36 standards and offers a balance of strength, ductility, and excellent weldability. It is a cost-effective choice for applications where precise dimensions and a smooth surface finish are not primary concerns.
As a medium-width flat bar, this 2-1/4" x 5/16" size is perfectly suited for structural bracing, machine ways, wear strips, and base plates. Its substantial thickness provides rigidity and strength for fabricators, construction crews, and maintenance teams building frames and supports.
