Spiral fire escape stairs for the MOD
Spiral UK have been supplying the MOD with spiral escape stairs for over 30 years, so not only are we experienced in their design and manufacture, but our installation teams are familiar with the extra security procedures required for working on military sites. All of our fire escape stairs deliver against the exacting standards demanded by the MOD.
Recently we have worked with Aspire Defence who are responsible for building, improving and maintaining soldiers’ single living and working accommodation at Tidworth, Bulford, Warminster, Larkhill, Aldershot and Perham Down garrisons.
We are also working with Skanska UK who have the contract to deliver new infrastructure and accommodation at Worthy Down Barracks near Winchester.
On all these projects the MOD requirement has been for robust and functional spiral staircases as a means of external escape on accommodation blocks. All the fire escape stairs are made from galvanised mild steel and compliant with British Standard BS5395 Part II (Code of Practice for the design of helical and spiral stairs 1984).
