The evacuation stairs forseen inside new buildings are mostly made from concrete and are as such an integral part of the building structure. But in old buildings that are being renovated there is often a need to add an inside fire escape stair and it is very difficult to make that out of concrete. Then JOMY has the perfect solution with their lightweight very strong aluminum stairs that are mounted on site without welding. Because of the weight no cranes or special handling equipment is needed.
The JOMY interior stairs are also used just for their cool and industrial look.
