- A36 Hot Rolled Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
Hot rolled (HR) flat bar is formed at elevated temperatures, resulting in a product with a distinctive scaly, blue-grey finish and slightly rounded edges. This A36 grade steel offers a minimum yield strength of 36,000 PSI, ensuring reliable performance in structural roles. Its carbon content provides excellent weldability using common methods like MIG and stick welding without pre-heating.
As a large-format flat bar, the 9-inch width is suited for heavy-duty applications where load distribution and rigidity are critical. Common uses include machinery base plates, heavy equipment mounting pads, trailer frame cross-members, and significant structural bracing where strength is the primary requirement.
