- A36 Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
Hot rolled A36 steel flat bar is formed at elevated temperatures, resulting in a product with a distinctive scaly, blue-grey finish and slightly rounded edges. This cost-effective process makes it more malleable than cold rolled steel. It conforms to ASTM A36, ensuring reliable structural performance with excellent weldability using common methods like MIG and stick welding.
The large 4-inch width of this bar makes it ideal for substantial load-bearing applications. Common uses include fabricating machinery base plates, heavy structural braces and supports, trailer frames, and components for industrial equipment where strength and durability are critical.
