Who we are

Capalex - Who we are?

Capalex, Capital Aluminium Extrusions Ltd, is an aluminium extrusion manufacturer and machining company with all extrusion, heat treatment, machining, fabrication, powder coating, and assembly facilities at a single site in Cleator Moor, Cumbria, United Kingdom.

We provide a greater range of alloys and more flexibility on profile design, tolerances, quantities and lead times than almost any of the larger scale commercial extrusion companies.

This can be particularly helpful to designers developing new products and for industries where flexible lower quantities, better tolerances and responsive quick deliveries are paramount.

We can also help when there is need for a very lightweight aluminium extrusion, producing profiles down to 0.02kg/m and 0.5mm thickness.

Our customers range from one man engineering shops to some of the biggest multi-nationals, spanning every market sector including Architectural, Automotive, Defence, Display, Electronics, Engineering, Furniture, Leisure, Marine, Product Design, Retail, Rail & Signage.

We are also able to work with the biggest aerospace companies with our AS9100D & ISO 9001:2015 approvals.


When incorporated in 1979 until June 1997 Capalex rented a 3,000 sq m factory built by English Estates on Leconfield Industrial Estate in Cleator Moor.

In June 1997 Capalex bought an adjacent 5,7,00 sq m site and operations transferred across to the new factory during that same year.

From this single site, Capalex now offers a one-stop shop aluminium extrusion service, with all manufacturing, machining and fabrication, powder coating, heat treatment, assembly, storage and stock holding, despatch and administrative functions under one roof delivering goods to all over world.
