Garnalex is an award-winning UK-based manufacturer specialising in the extrusion of grade 6063 aluminium. We use state-of-the-art technologies for production efficiency, sustainability, and cost-savings. To date, we’ve invested over £27 million to ensure our quality and service are second to none. This is of benefit to our trade partners around the UK, as well as those who purchase our Sheerline aluminium window, door, and roof products. In 2025, Garnalex was honoured to receive a King’s Award for Innovation 2025 for aspects of the Sheerline system. This award recognises the significant contribution and advances we’ve made within the fenestration industry. We understand successful trade extrusion is about more than just price. It’s about quality, service, reliable supply and someone to talk to when you need support. If this is the kind of trade extrusion partner you’d like to work with, email us: info@garnalex.com.
