Hot Rolled Steel Flat Bar - 5-1/2 Inch X 5/8 Inch
This 5-1/2" x 5/8" hot rolled steel flat bar is a general-purpose structural A36 steel, conforming to ASTM A36 specifications. It offers a minimum yield strength of 36,000 PSI and excellent weldability, making it ideal for fabrication, construction, and repair. In stock Los Angeles.
- A36 Carbon Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
A36 hot rolled steel is formed at elevated temperatures, creating a product with a distinctive scaly, blue-grey mill finish and slightly rounded edges. This process results in excellent formability and weldability. Conforming to ASTM A36, this low-carbon steel has a minimum yield strength of 36,000 PSI, providing reliable performance in structural roles without the tight tolerances of cold rolled steel.
As a large-profile flat bar, this 5-1/2" width provides substantial surface area and strength for heavy-duty applications. It is commonly used for machinery base plates, trailer frame cross-members, heavy equipment mounting brackets, and other robust structural supports where load-bearing capacity is critical.
