Description

The 40mm x 5mm aluminium flat bar is a reinforced medium-heavy extrusion profile made from EN AW-6063 aluminium alloy in T6 temper. With its broad 40 mm surface and 5 mm thickness, this profile delivers excellent strength and dimensional stability—ideal for structural support, framework reinforcement, and custom fabrication tasks across industrial and commercial environments.

Its proportions make it especially effective in applications where both coverage and rigidity are required, such as base plates, machine panels, mounting brackets, and assembly lines. The 5 mm thickness ensures reliable resistance to deflection under static loads while remaining workable for machining and drilling.

Delivered with a smooth mill finish, this profile can be anodised or powder coated on request to meet specific aesthetic or corrosion resistance needs. It is compatible with CNC processing, welding, cutting, and surface treatment operations.

Each bar is supplied in 6-metre standard lengths. Tailored cutting and finishing options are available for scaled projects.

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.
