About Us


Established and Early History

Formed in 1979, Capital Aluminium Extrusions Ltd, Capalex is an independent aluminium extrusion company with all manufacturing, machining and fabrication, powder coating, heat treatment, assembly, storage and stock holding, despatch and administrative functions under one roof at a single site factory in Cleator Moor, Cumbria.

Capalex was started by 2 former employees previously employed by another large aluminium extruder in the local area. The former employees bought the smaller of the two extrusion presses from the previous company and commenced business, specialising in making small, tight tolerance extrusions to order. Uniquely amongst extruders they offered a 'no minimum quantity' service with excellent lead times and the company has prospered since.



Since incorporation in 1979 until June 1997 Capalex rented a 30,000 sq ft factory built by English Estates on Leconfield Industrial Estate in Cleator Moor. In June 1997 Capalex bought an adjacent 57,000 sq ft site and the company’s operation was transformed across to the new factory during that year.

Capalex Factory, Acquired in 1997



A second extrusion press and production line was installed in late 1995, and since then, there has been continuous investment in equipment for precision machining, powder coating, heat treatment and testing.


Capalex also acquired it's first direct extrusion press, a new 850 Metric Tonne model in 2014, maintaining 3 active presses while broadening Capalex's capability. The company also continually improves its CNC machining and automated machining facilities by adding new machines as and when required. We currently have 10 CNC precision macines which will continue to grow in the future.
