TAS temporary steel stairs
TAS temporary steel stairs are developed and manufactured by TLC for construction sites where temporary access between different levels is required. The 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 available in 3-, 6-, 9-, 12-, 15- and 18-step modules, allowing the staircase configuration to be selected according to the required working height and site conditions. Depending on the selected module, the inclination angle can be adjusted from 0° to 50°, and individual stair flights can be connected using dedicated connectors and supports.
Using dedicated accessories, the TAS System can also be configured as temporary gangways, step-over platforms and scaffold access stairs, allowing different temporary access solutions to be created using one modular system.
1 – Anti-skid and self-cleaning steps
2 – Safety locks preventing from folding
3 – Practical transport grips
4 – Anti-skid grips at bottom and top of the stairs
5 – Single or double railing
6 – Socket for fast railing instalation
7* – Possibility to use a handle lowering last step
The stairs meet the requirements of the PN-EN 12811-1:2007 requirements regarding the class 1 carrying capacity (1,5 kN on 200x200mm surface) and are adapted for self-assembly with the use of a crane.

Key features of TAS temporary steel stairs
- Modular stair system
The TAS System is available in modules with 3, 6, 9, 12, 15 and 18 steps, allowing the staircase configuration to be adapted to different construction site requirements and working heights.
- Adjustable inclination angle
Angle regulation from 0° to 50° for 3-, 6-, 9- and 12-step modules, and from 25° to 50° for 15- and 18-step modules.
- Usable width of 700 mm or 1000 mm
The TAS System is available with a usable width of 700 mm or 1000 mm, allowing the appropriate staircase configuration to be selected according to project requirements.
- Possibility to connect stair flights
Individual stair flights can be connected using connectors and supports (e.g. 18+18 or 15+12 steps).
- Compatible with additional temporary access solutions
Using dedicated accessories, the TAS System can also be configured as temporary gangways, step-over platforms and scaffolding stairs
- Anti-slip stair treads
The stair treads are designed with an anti-slip surface for construction site applications
- Railings mounted on one or both sides
Railings can be installed on one or both sides of the staircase depending on the selected configuration.
- Safety locks preventing folding
Safety locks prevent the staircase from folding.
- Compliant with PN-EN 12811-1:2007
The TAS System complies with the requirements of PN-EN 12811-1:2007, class 1 carrying capacity (1.5 kN on a 200 × 200 mm surface).

Length selection and stair setup
The stair position, including the inclination angle and the distance between the lower and upper support points, can be determined using the diagram shown on the right.
Follow these steps:
- Determine the excavation depth and mark the value on the vertical axis.
- Based on the selected stair module (number of steps), determine the stair inclination angle by drawing a horizontal line to the point where it intersects the corresponding curve.
- Determine the position of the lower support point of the stairs by drawing a vertical line from the intersection point to the horizontal axis.
