Aluminum Flat Bar

Aluminum flat bar is a lightweight, corrosion-resistant material that is easy to weld, cut, drill, and machine. It offers excellent strength while remaining easy to work with, making it suitable for both structural and precision applications.

Commonly used for brackets, supports, base plates, frames, and machined components, aluminum flat bar is widely used in construction, manufacturing, and aerospace and high-performance applications where strength and weight reduction are critical.

Available in widths from 1/2” to 12”, with thicknesses from 1/8” to 1”.
