UK based aluminium trade extruders 

Driven by innovation, investment and passion

Specialising in the Agile Supply of Grade 6063 Aluminium Extrusion

We understand that successful trade extrusion is about more than just price, it’s about service and support levels coupled to reliable supply

Formed in early 2018 by Roger Hartshorn, who after 40 years experience in the fenestration industry saw the opening for a modern UK based aluminium extruder. Trade extrusions are produced on our state-of-the-art SMS HYBREX aluminium press and delivered using our own logistics fleet, for consistent deliveries from known drivers. 

We’ve invested over £15 million to-date in ensuring our service and quality is second to none. Designed and refurbished to the highest standards, our 100,000 sq ft factory, based in Derbyshire is the most modern aluminium facility in the UK. Our attention to detail enables us to offer the most reliable, consistent service possible.

The SMS HYBREX aluminium press that sits at the heart of our operation utilizes high speed die changes to maximise production efficiency. Best practice lean manufacturing calls for Single Minute Exchange of Dies, but our tool changes are six times faster. Featuring high levels of automation, our plant has a 54m long cutting and stacking area, which feeds into our annealing oven. All supported by the latest integrated computer systems.

Case study:
‘Great’ service and support from Garnalex supports profine in challenging times

profine Extrusions UK, the systems company behind WarmCore, recently switched to source its aluminium profiles from Garnalex, the UK-based aluminium extrusions company. profine had been experiencing prolonged supply chain problems from China, but within just a few weeks Garnalex had eliminated the problem and delivered the product. 

Mateusz Prudlo, Purchasing Manager of profine, comments: “The recent support from Garnalex has meant we can continue to maintain our high level of service to customers. Instead of having to wait 12 weeks for supply from China, Garnalex cut the profile dies and supplied the profiles within just a few weeks. The quality of the manufactured product was great, as was the service and support throughout. I have only positive things to say about our experience of working with Garnalex.” 

Roger Hartshorn, CEO of Garnalex, adds: “Following the European Commission’s proposal to impose anti-dumping duties on imported aluminium from China, the support we provided to profine highlights just how important it is to invest in British manufacturing and buy locally. Companies who buy from China can expect prices to increase, as well as the already long lead times. By extruding in the UK, we’re able to take full control of the supply chain and offer shorter lead times and outstanding quality and service. This is exactly what we provided to profine.” 

From its set up in 2018, we’ve invested heavily in Garnalex’ vertically integrated supply chain so we could provide this unprecedented level of service, quality and support. All raw aluminium logs are sourced from Wales which saves time, unnecessary carbon road miles and minimises the uncertainty of supply and quality. Garnalex is proud to be Made in Britain. It’s becoming clearer that it’s also prudent to make in Britain too.
