DESCRIPTION

A36 hot rolled steel flat bar (1/8″ x 4″) is manufactured from low-carbon structural steel and produced to ASTM A36 specifications for general construction and fabrication applications. This flat bar features a rectangular profile with a thickness of 1/8 inch and a width of 4 inches, offering good weldability, machinability, and formability. The hot rolled finish provides a scaled surface with slightly rounded edges, making it suitable for structural components and general industrial use where precise tolerances are not required.

Applications:
A36 hot rolled steel flat bar is commonly used in structural, mechanical, and fabrication applications, including:
• Base plates, brackets, and support components
• Structural framing and reinforcement
• Equipment and machinery fabrication
• Repair and maintenance work
• General construction and metalworking applications
• Spacer plates and fabrication assemblies

Advantages:
• High strength: Meets ASTM A36 structural strength requirements
• Excellent weldability: Easily welded using standard methods
• Good machinability: Suitable for cutting, drilling, and forming
• Cost-effective: Economical choice for structural and general-purpose use
• Versatile: Ideal for a wide range of fabrication and repair applications

Summary:
The 1/8″ x 4″ A36 hot rolled steel flat bar is a durable, versatile, and cost-effective material designed for structural, industrial, and general fabrication applications. Its strength, ease of fabrication, and broad usability make it a reliable choice for construction, reinforcement, and manufacturing projects.

* Prices are subject to change without notice due to fluctuations in the metals market. | All “Value Length” and “Value Pack” item measurements are subject to standard mill tolerances. | Products may be manufactured several thousandths of an inch over or under the stated dimensions and still be within acceptable mill tolerances. All bar, tube, structural, pipe, sheet, plate, and similar products sold on our website are custom cut to the lengths and sizes selected by the customer at the time of purchase. These are not stocked as pre-cut items. Because each order is cut specifically to customer specifications, all cut materials are considered custom products and are not eligible for cancellation, return, or exchange once production has begun. Our standard cutting tolerances are:

  • Length: +0.125″ / -0.062″
  • During the cutting process, the saw blade removes approximately 1/16″ (kerf) of material. This is a normal part of the manufacturing process and is already included within the stated cutting tolerances.
