SST SPIRAL STAIRS
SST SPIRAL STAIRS

Temporary Spiral Staircase SST is a new product of the TLC Group, which is an alternative solution
for TAS – temporary stairs and staircases. Stairs are used on construction sites, where they easily
enable to provide communication between levels on a construction site.

The system consist of a base frame, intermediate module, descent step or descent landing. The construction
is protected by hot-dip galvanization and designed according to PN EN 12881 standards.

Stairs are assembled as pre-braced intermediate modules which are set on a base frame with four adjustable feet and stabilised with consoles mounted on a stable base, for proper assembly and operation stairs must be mounted on a levelled concrete substrate Due to its temporary use, installation on reinforced concrete slabs or concrete blocks is permitted. If blocks are used, it is a prerequisite that they are set on a hardened gravel bed with an effective drainage system in a secure and stable manner.
