A36 Hot Rolled Steel Flat Bar - 8" x 3/4" x 240"

This 8" x 3/4" A36 Hot Rolled Steel Flat Bar is a versatile structural material offering excellent strength and weldability. Conforming to ASTM A36, its substantial size is ideal for heavy fabrication, including base plates, supports, and frame components. In stock Los Angeles.

  • A36 Steel Construction
  • ASTM A36 Certified
  • 58,000-80,000 PSI Tensile Strength
  • Excellent Weldability
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

A36 Hot Rolled Steel is a low-carbon structural steel produced to ASTM A36 standards. The hot rolling process gives it a characteristic scaly, blue-grey finish and slightly rounded edges, along with looser dimensional tolerances than cold rolled steel. This makes it a cost-effective choice for applications where strength and weldability are more critical than surface finish. It offers good machinability and can be easily fabricated using conventional methods.

As a large format bar, this 8" x 3/4" size is engineered for heavy-duty structural applications. Its substantial cross-section provides excellent load-bearing capacity, making it a primary choice for fabricating machinery base plates, heavy structural braces, frame components for transportation equipment, and industrial wear strips where durability is essential.

Specifications

  • Material: A36 Steel
  • Standards: ASTM A36
  • Strength/Tensile: 58,000-80,000 PSI
  • Dimensions: 8" Width x 3/4" Thickness x 240" Length
  • Finish: Hot Rolled, Mill Finish
  • Certifications: MTR Available upon request

Applications

  • Structural Engineering: Base plates for columns and heavy machinery - Excellent compressive strength and easy to drill/weld.
  • Heavy Equipment Manufacturing: Frame components, stiffeners, and mounting brackets - High strength and durability to handle heavy loads.
  • General Fabrication: Large gussets, supports, and cross-members - Cost-effective and readily formable for custom structural work.
  • Industrial Maintenance: Reinforcement sections for bridges and structures - Tough material for heavy-duty repairs and retrofits.

Target Users

Structural fabricators, heavy equipment manufacturers, and industrial maintenance crews rely on A36 flat bar for robust and reliable structural components in projects throughout the Los Angeles area.

Finish Options

This product comes standard with a hot rolled mill finish, characterized by a dark, scaly surface. This mill scale must be removed by grinding, sandblasting, or pickling before painting, powder coating, or galvanizing. Left unfinished, it will rust. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Flat bar is measured by its Width (the larger flat dimension) and its Thickness (the smaller dimension). Calipers are recommended for an accurate measurement.

Example: To order this flat bar, specify "A36 Hot Rolled Flat Bar, 8 Inch width by 3/4 Inch thickness".

Order Checklist

  • Product name and required dimensions (8" x 3/4" x 240")
  • Material specification and quantity
  • Confirm grade (A36) meets project requirements
  • Surface finish requirements (Hot Rolled)
  • Certifications required (Mill Test Report)
  • Special cutting, handling, or delivery requirements
