Description

The 55mm x 12mm aluminium flat bar is a robust extrusion profile manufactured from EN AW-6063 aluminium alloy in T6 temper. With its substantial thickness and broad width, this profile is designed for demanding structural and mechanical applications that require durability and dimensional stability.

Ideal for heavy-duty framing, base plates, machine components, and industrial brackets, the 12 mm thickness delivers excellent rigidity and load-bearing capacity. The 55 mm width allows for wide surface contact, making it suitable for both mechanical and architectural integration.

Its smooth mill finish and extrusion precision ensure compatibility with CNC cutting, drilling, and surface treatments. Optional finishes such as anodising and powder coating are available for added protection or aesthetic requirements.

➤ Minimum order quantity: 500 kg.

➤ Worldwide delivery via road, sea, or air freight.
