DESCRIPTION

3/4″ x 1-1/4″ Steel Flat Bar A36 Hot Rolled is a heavy-duty, low-carbon structural steel bar designed for high-strength fabrication, reinforcement, and load-bearing applications. Manufactured to ASTM A36 specifications, this flat bar delivers dependable strength, excellent weldability, and versatility across industrial, commercial, and construction projects.

The hot rolled (HR) finish features a scaled surface with rounded edges, providing a cost-effective solution for structural applications where tight tolerances and smooth finishes are not required. With its substantial 3/4″ thickness, this flat bar offers superior rigidity and durability, making it ideal for demanding environments.
