DESCRIPTION

The 3″ x 4″ Rectangular Aluminum Flat Bar 6061-T6 Structural is manufactured from heat-treated 6061-T6 aluminum alloy, known for its excellent strength-to-weight ratio, machinability, and corrosion resistance. This structural-grade flat bar features a solid rectangular profile with precise dimensional tolerances, making it ideal for load-bearing and fabrication applications. The T6 temper indicates solution heat-treated and artificially aged material, providing enhanced mechanical properties and improved structural performance.

6061-T6 aluminum offers good weldability and can be easily machined, drilled, or cut to size, making it a versatile material for both industrial and general-purpose projects.

Applications:
The 3″ x 4″ 6061-T6 Rectangular Aluminum Flat Bar is commonly used in structural and fabrication applications, including:
• Structural supports and framework
• Equipment bases and mounting plates
• Bracing, reinforcement, and load-bearing components
• Trailer, truck, and automotive fabrication
• Marine and outdoor structural projects
• General construction and custom metal fabrication

Advantages:
• High strength-to-weight ratio: Strong yet lightweight compared to steel
• Corrosion resistant: Performs well in outdoor and marine environments
• Excellent machinability: Easily drilled, tapped, and milled
• Weldable: Suitable for TIG and MIG welding applications
• Structural-grade material: T6 temper provides enhanced strength and durability
• Versatile use: Ideal for both heavy-duty and precision fabrication projects

Summary:
The 3″ x 4″ Rectangular Aluminum Flat Bar 6061-T6 Structural is a strong, lightweight, and corrosion-resistant material designed for demanding structural and fabrication applications. Its T6 heat treatment ensures reliable strength and performance, while its machinability and weldability make it an excellent choice for construction, industrial, marine, and custom fabrication 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.
