- A36 Carbon 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 provides a reliable 36,000 PSI minimum yield strength and can be easily welded, drilled, and formed, making it a foundational material for general fabrication.
As a large-format bar, this 9-inch wide piece is perfectly suited for applications requiring significant strength and surface area, such as machinery base plates, heavy structural supports, die components, and reinforcement sections for large equipment and trailer frames.
