- A36 Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability
A36 hot rolled flat bar is produced by forming steel at elevated temperatures, resulting in a product with a scaly, blue-grey finish and slightly rounded edges. This cost-effective process makes the material tough and easy to form. Primarily governed by ASTM A36, this low-carbon steel offers reliable performance in structural roles with excellent weldability using common methods.
As a medium-sized flat bar, this 1-1/8" x 1/2" dimension is highly versatile. It is frequently used for structural bracing, equipment frames, base plates, wear strips on machinery, and custom brackets where a balance of strength and formability is essential.
