TAS temporary staircase
TAS temporary steel stairs are used on construction sites where temporary access between different levels is required. Developed and manufactured by TLC, the modular system supports access over small and larger height differences and can be used as temporary stairs for construction, construction site stairs or temporary site stairs.
The TAS System is modular and available in modules with 3, 6, 9, 12, 15 and 18 steps Angle regulation is available from 0° to 50° for modules with 3 to 12 steps, and from 25° to 50° for 15- and 18-step modules.
TAS temporary stairs can be used as temporary stairs, gangways, scaffolding stairs, step-over platform or as part of TAS staircase configurations. Steel TAS stairs are available with a usable width of 700 mm or 1000 mm.
The system allows stair flights to be connected using connectors and supports. TAS stairs are assembled on a previously prepared surface by fixing the lower and upper part of the module.
Key features of TAS temporary staircase
- Modular system available in 3-, 6-, 9-, 12-, 15- and 18-step modules
- Angle regulation from 0° to 50° for 3–12-step modules and from 25° to 50° for 15- and 18-step modules

Height adjustment of TAS temporary staircase
The TAS staircase descent is used to reduce level differences between the staircase and the target platform or ground level.
The system allows height adjustment in 7 positions, with 195 mm increments. This makes it possible to adapt the stair exit level to different site conditions and required access heights.
For more precise height adjustment, additional TAS steps can be used. Available options include 3-step and 6-step sets, mounted with a TAS Support adapter.

Technical description of TAS temporary staircase
The TAS temporary staircase system is used on construction sites where temporary access between different levels is required. It can be applied during different stages of construction, especially where a modular temporary stair solution is needed.
The system consists of stair modules, platforms, railings, posts and brackets. The modular construction allows different staircase configurations depending on the required height, angle of inclination and site conditions.
TAS stairs are developed in accordance with PN-EN 12811-1:2007. The system is made of steel S235 and S355 and protected with a hot-dip galvanised finish.
Technical parameters:
- Permissible distributed load on platforms and stairs: 1.0 kN/m²
- Usable width of stairs and platforms: 700 mm
- Materials: steel S235 and S355
- Corrosion protection: hot-dip galvanised
