Fortis Doors  – The history.

Fortis Aluminium are proud to manufacture our range of energy efficient, high security door systems in Leicester, Great Britain. We source over 90% of our components in the UK resulting in less transport and a lower carbon footprint than other aluminium door systems. Function and form are key in our design and manufacturing process to ensure that each door we produce in our Leicester factory will last for years to come.

Only the highest grade materials are good enough for a Fortis door. Our doors are engineered to last and withstand the toughest of environments, every small detail of every single door we produce is considered and perfected. Our doors are all hand made in our purpose built factory from marine grade, corrosion resistant alloys, 304 and 316 grade stainless steel and argon filled, high security triple glazing as standard.

Who can use the official “Made in Britain” collective mark?

The Made in Britain mark is accredited to businesses that sell goods that have been manufactured or have undergone a final substantial change in Britain before sale. All companies that apply to use the Made in Britain mark have been asked to submit written evidence that they manufacture their products in Britain. This has now been approved.

Made in Britain adheres to advice on country of origin labelling included in the Trade Descriptions Act 1968. Country of origin is therefore the country in which a product last underwent a final treatment or process resulting in a substantial change.


Doors will be quoted in standard specification unless otherwise stated with satin glass. All prices are subject to survey. For an accurate quotation please use our ‘Design my door tool’
