All of our Flat Aluminium Bars and Aluminium Flat Strips are extruded. The extrusion process produces bars that have perfectly square edges, and nice square corners. Unlike sawn Aluminium Plate and guillotined Aluminium Sheet, the corners of the section are smooth, and not sharp to touch. Therefore, only the cut ends are likely to need treating or filing before the Aluminium Flat Bar can be used as a finished product without the chance of accidental injury.

All of our Metric Aluminium Flat Bars and the vast majority of our Imperial Aluminium Flat Bars are supplied in grade 6082T6. This is a great general engineering grade of aluminium. Aluminium Flat Bars in grade 6082T6 (also known as grade H30) are suitable for machining, tapping and drilling. It has good strength properties and is used for structural applications. Aluminium Flat Bars also have good weldability properties – if you require your aluminium flat bar welding, please contact us for a quote. Aluminium Flat Bars also have excellent anti corrosive properties, and they are also suitable for polishing, powder coating and anodising.

The larger, heavier sections are often machined to size to create smaller components for the automotive, rail and other manufacturing industries.
