Description

The 25mm x 20mm aluminium flat bar is a heavy-section extrusion profile manufactured from EN AW-6063 aluminium alloy in T6 temper. With its large 20 mm thickness and 25 mm width, this profile offers exceptional compressive strength, rigidity, and stability—making it highly suitable for structural applications under significant mechanical load.

This profile is commonly used in load-distributing base plates, custom machine components, press tooling supports, structural columns, and high-impact fabrication environments. Its solid mass ensures minimal deflection and long-term dimensional reliability even in demanding operational conditions.

Supplied with a clean mill finish, the bar is fully compatible with CNC machining, milling, drilling, and surface treatments such as anodising or powder coating to enhance performance in corrosive or abrasive environments.

Each bar is available in 6-metre standard lengths. Cut-to-size and custom surface finishing services can be provided for large-scale 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.
