Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

A36 hot rolled steel flat bar is formed at high temperatures, resulting in a product with a distinctive scaly, blue-grey finish and slightly rounded edges. This process makes it more malleable and cost-effective than cold rolled steel. Conforming to ASTM A36, it provides a minimum yield strength of 36,000 PSI and is easily fabricated, drilled, and welded.

As a large-format flat bar, this 12-inch wide material is ideal for manufacturing heavy-duty machinery base plates, structural supports, die components, and girder stiffeners where maximum strength and load distribution are critical requirements for the application.

Specifications

  • Material: A36 Hot Rolled Steel
  • Standards: ASTM A36
  • Strength/Tensile: 58,000-80,000 PSI
  • Dimensions: 12" Width x 3/4" Thickness x 240" Length
