This 1-1/4" x 3/4" Hot Rolled Steel Flat Bar is a general-purpose structural A36 steel with excellent weldability. Conforming to ASTM A36 specifications, it offers a minimum 36,000 PSI yield strength, ideal for frames, supports, and fabrication. In stock Los Angeles.
- A36 Hot Rolled Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability
Hot rolled A36 steel flat bar is formed at elevated temperatures, resulting in a scaly, blue-grey finish and slightly rounded edges. This process makes it more cost-effective than cold rolled steel. It is produced to meet ASTM A36 standards, ensuring a reliable minimum yield strength of 36,000 PSI for structural applications and excellent weldability.
As a medium-width bar, this 1-1/4" x 3/4" size is highly versatile. It is commonly used for structural bracing, machine ways, wear strips for heavy equipment, and building frames where a balance of strength and formability is required.
