What is an Aluminium Flat Bar?

An aluminium Flat Bar is an extrusion often referred to as an aluminium rectangular bar or a flat aluminium strip. It is a length of aluminium with a rectangular cross-section that varies in dimensions.

All our supplied Aluminium flat bars are made from 6000 series aluminium, which is alloyed with magnesium and silicon, making the extrusion highly corrosion-resistant and formable.


What are Aluminium Flat Bars used for?

Aluminium flat bars are versatile extrusions often used in construction, for internal fixtures as well as frame building and machining parts. It has a superb strength-to-weight ratio, strong resistance to corrosion and, being formable, it’s easy to machine, weld, cut and drill.

It is ideal for outdoor use thanks to its corrosion resistance. If not anodised, aluminium will naturally oxidise when used outdoors, creating an oxide layer on the surface of the extrusion that amplifies the corrosion resistance of the aluminium.


How strong is an Aluminium Flat Bar?

Though not as strong as steel, 6000 series aluminium still offers enough strength to be an ideal choice for many applications including structural use. However, aluminium is 1/3 the weight of steel, which gives it a fantastic strength-to-weight ratio. This ultimately means aluminium is an ideal material to be used where you need reliable support without the risk of overloading the weight.
