A36 Hot Rolled Steel Flat Bar - 3-1/2" x 1/2"
A 3-1/2" x 1/2" structural flat bar made from A36 hot rolled steel, meeting ASTM A36 specifications. This bar provides a minimum yield strength of 36,000 PSI and excellent weldability, making it a reliable choice for heavy fabrication and structural supports. In stock Los Angeles.
- A36 Hot Rolled 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 high temperatures, resulting in a product with a distinctive scaly, blue-grey finish and slightly rounded edges. This cost-effective process produces a versatile structural steel that conforms to ASTM A36, offering 36,000 PSI minimum yield strength. It is easily welded, drilled, and formed, making it a foundational material for general fabrication.
This bar's substantial 3-1/2" width and 1/2" thickness classify it as a large structural component. It is perfectly suited for manufacturing machinery base plates, heavy-duty frame components, trailer chassis cross-members, and other applications where maximum strength and load-bearing capacity are critical.
