The basis module is worked out as a table on 4 strong supports (200x100). On top there is a steel deck that can be worked out with green roof cassettes.
The walls can be realised with strong 8-6-8 welded wire mesh, with perfoplates, glass panels or with wooden slats.
A large and strong sliding or revolving door can be installed to give access to the shelter with a mechanical lock or with badge/smartphone system.
Larger constructions can be realised by combining extension modules to the basic module.
