Description

The 20mm x 3mm aluminium flat bar is a versatile extrusion profile manufactured from EN AW-6063 aluminium alloy in T6 temper. With its moderate width and reinforced 3 mm thickness, this profile delivers increased rigidity while maintaining lightweight handling characteristics—ideal for a wide range of fabrication and structural support applications.

It is commonly used in machine guards, frame reinforcements, mounting plates, trim elements, and equipment housing components. The 3 mm thickness offers improved load resistance compared to thinner alternatives, making it suitable for parts exposed to moderate stress or frequent handling.

This profile comes with a smooth mill finish and is suitable for CNC machining, cutting, drilling, and surface treatments. Powder coating and anodising options are available on request to enhance corrosion protection or visual appeal.

Supplied in standard 6-metre lengths. Custom lengths and cut-to-size options can be arranged for project-based requirements.

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.
