Fortis Aluminium are a UK based door factory specialising in unique, made to measure hand crafted aluminium doors. Each and every one of our doors are built from raw materials and carefully sourced components in Leicester, England. As a smaller specialist family business, we have the flexibility to realise your design ambitions and craft a door to suit your specific needs and requirements.

We know purchasing a door is an important moment and we want to make sure we get your requirements right – right from the start.

Backing British manufacturing, working with European partners

Over 90% of each of our doors is built from high grade British components.

Our high quality magnesium based alloy door plates are manufactured in house using our state of the art equipment. The range of bespoke handles are individually made here in the Midlands. Our highly efficient security glass units are produced in Peterborough. Even our PU insulated core material is made right here. We also integrate efficient German profiles and high security lock systems in to each and every door.

Most of our competitors build and ship their doors from Eastern Europe. Our ‘Made in Britain’ approach supports British industry and minimises our carbon footprint.
