A36 Hot Rolled Steel Flat Bar is a low-carbon structural steel produced to ASTM A36 specifications for general construction, fabrication, and industrial use. The 3/8″ x 8″ flat bar features a solid rectangular profile with a hot rolled finish, providing a balance of strength, weldability, and machinability. The hot rolling process gives the material a mill scale surface and slightly rough finish, while maintaining excellent structural performance for heavy-duty applications.
Applications:
A36 Hot Rolled Steel Flat Bar is commonly used in structural, mechanical, and fabrication applications, including:
• Structural framing and support components
• Base plates, brackets, and reinforcement plates
• Welding and metal fabrication projects
• Machinery and equipment repair or assembly
• Industrial construction and general steelwork
• Custom manufacturing and structural modifications
Advantages:
• Strong and durable: Provides reliable performance for structural and load-bearing applications
• Excellent weldability: Easily welded using standard welding processes
• Good machinability: Can be drilled, cut, and formed with common tools
• Cost-effective: Widely available and economical structural steel option
• Versatile use: Suitable for a wide range of industrial and construction applications
Summary:
The 3/8″ x 8″ A36 Hot Rolled Steel Flat Bar is a heavy-duty structural steel product designed for strength, versatility, and reliability in fabrication and construction. Its solid profile and weldable properties make it an excellent choice for structural support, repairs, and industrial metalworking projects.
