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 subject to change without notice due to the Metals Market fluctuations. | All ‘value length’ and ‘value pack’ item measurements are subject to a “mill tolerance”. | A product may be produced several thousandths of an inch, either over or under the stated thickness, and still be within “mill tolerance”. Since we cut the material specifically for your order, they follow these tolerances: Length: +0.125″ / -0.062” – Please note that during cutting, the blade removes about 1/16″ of material (kerf). This is a normal part of the process and is already considered within the stated tolerances.
