Aluminium Square Bar 71mm x 71mm
Description
The 71mm x 71mm aluminium square bar is a large-section extruded profile made from EN AW-6063 aluminium alloy in T6 temper. Engineered for structural performance, it offers superior strength, corrosion resistance, and dimensional integrity in heavy industrial environments.
This profile is used in machine bases, structural columns, support frameworks, large-scale welded systems, and platform constructions. Its solid form is well-suited for high-load applications and allows for accurate CNC machining, drilling, welding, and finishing operations.
Supplied in standard 6-metre lengths with a mill finish. Optional surface treatments such as powder coating or anodising are available to meet aesthetic or environmental demands. Custom lengths and cut-to-size services can be arranged depending on your project scope and quantity.
We supply aluminium bars to manufacturers, fabricators, and project contractors across various industries, supporting their needs for consistent quality and scalable production.
➤ Minimum order quantity: 500 kg.
➤ Delivery available worldwide via land, sea, or air freight.
