Aluminium Square Bar 15mm x 15mm
Description
The 15mm x 15mm aluminium square bar is a robust and versatile extruded profile made from EN AW-6063 aluminium alloy in T6 temper. It offers excellent corrosion resistance, dimensional accuracy, and machinability for demanding industrial applications.
Its balanced size and strength make it suitable for a variety of medium-load structural assemblies such as machine frames, support brackets, modular systems, and custom welded constructions. The profile is ideal for CNC cutting, drilling, surface finishing, and production-scale fabrication.
Supplied in standard 6-metre lengths with mill finish, the bar can also be delivered with optional powder coating or anodising depending on environmental and aesthetic requirements. Custom cutting and project-based length options are available upon request.
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.
