Aluminium Couplers, Hooks and Fittings

What can we do for you

When Alistage was started over 35 years ago, the founder realised that he could not buy the equipment he needed fast enough to react to market needs. As a result, he developed our own aluminium manufacturing facility.

Today, our factory has clients across the globe, from New Zealand to North America, South America, the Middle East to Europe and of course the UK.

Today multiple manufacturers around the world manufacture couplers according to our original design that withstood the test of time and hasn’t changed since 1990.  You will find our couplers, hooks and fittings used in multiple industries and on various structures – ranging from video walls, lighting rigs, camera mountings, construction platforms, farm machinery and many more. Many of our clients are aluminium fabricators themselves and they rely on us to make these critical component parts. – We supply OEM (Original Equipment Manufacturer).

We are very proud to say that we manufacture all our products in Great Britain, in our factory facility on the M25 north of London.

Colin, our factory manager has been with us since leaving school over 35 years ago. He has held literally every job in the factory before becoming the manager over 20 years ago. Together with our highly experienced welders and fabricators, our team is one of the leading manufacturers of aluminium fabricated structures in the UK. Unfortunately, our factory manager still hasn’t mastered the art of making a descent cup of tea, but other than that he is still learning something new on the job every day.
