Aluminium Flat Bar 46mm x 20mm
Description
The 46mm x 20mm aluminium flat bar is a robust, precision-extruded profile manufactured from EN AW-6063 aluminium alloy in T6 temper. Its 20 mm thickness and wide 46 mm face provide an excellent combination of strength, stiffness, and surface area—making it ideal for structural base plates, machinery fixtures, and load-distribution applications.
Frequently used in industrial fabrication, framework reinforcement, and component integration, this profile performs exceptionally well in environments where dimensional stability and machinability are critical. Its consistent geometry supports efficient cutting, CNC machining, and fastening processes.
Supplied in a smooth mill finish by default, the bar can be customised with anodised or powder-coated finishes to enhance corrosion protection or match project-specific aesthetics.
Each bar is delivered in standard 6-metre lengths. Custom lengths and cut-to-size services are available for volume orders.
We supply aluminium flat bars to manufacturers, fabricators, and contractors seeking consistent quality and reliable supply for their operations.
➤ Minimum order quantity: 500 kg.
➤ Worldwide delivery via road, sea, or air freight.
