- A36 Mild Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
Hot rolled (HR) 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 process makes it more malleable and cost-effective than cold rolled steel. It conforms to ASTM A36 specifications, ensuring a minimum yield strength of 36,000 PSI and excellent weldability for structural reliability.
As a small-profile flat bar, this 5/8" width is perfectly suited for light-duty fabrication projects. Common applications include manufacturing custom brackets, support straps for equipment, alignment shims, and creating framework for gates, fencing, and other ornamental ironwork where strength is a key requirement.
