A medium to high strength lightweight alloy with great corrosion resistance. Aluminium flat has almost limited applications including shelving, screens and construction. Our huge range is available for next day delivery to most of the UK.

We can also offer a variety of fabrication options and finishes, including cutting, slotting, drilling, powder coating, polishing and anodising.


Great strength to weight ratio


Excellent corrosion resistance


One of the planets most abundant raw materials


Almost infinitely recyclable


Aluminium flat bars sizes - metric and imperial systems

In the UK, it is commonplace to use the metric system in most weights and measures and has been since 1974, however, some people still use the imperial system. Use our handy conversion table to find the metric match for your imperial dimensions, ensuring your aluminium flat bar size is a precise fit. For more information and detailed diagrams please view our Brochure.
