Aluminium Square Bar 20mm x 20mm
Description
The 20mm x 20mm aluminium square bar is a heavy-duty extruded profile manufactured from EN AW-6063 aluminium alloy in T6 temper. Engineered for structural strength and dimensional precision, this profile is ideal for load-bearing assemblies and repetitive industrial processes.
Typical applications include machine bases, heavy-duty frames, support brackets, workshop systems, and custom fabricated parts. Its robust cross-section and high machinability make it well-suited for CNC processing, surface treatment, and welded construction.
Supplied in 6-metre standard lengths with a clean mill finish. Powder coating or anodising can be applied upon request to enhance surface durability and visual appeal. Custom length cutting is available depending on project specifications and volume.
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.
