PERI UP Flex Stair 75

The lightweight stair tower for quick and flexible access solutions

PERI UP Flex 75 Stair is a lightweight, efficient and versatile access system ideal for use on construction projects of all scales and sectors such as refurbishment, building construction and infrastructure.

The lightweight aluminium flights of stairs with 75cm widths are mounted on ledgers of the PERI UP modular scaffolding. The 4-legged stair towers can be configured with alternating staircase units or staircase units in the same direction and heights of up to 100m.

The PERI UP Flex Stair 75 is designed to accommodate 2.00 kN/m² loads and serves as access to working areas or around construction sites. 

All of the safety systems expected from PERI UP scaffolding are included such as gap-free, low-slip decks, self-locking ledgers, anti-uplift decks and reduced manual handling risk.

Stairwell Access

Access in stairwells requires a compact access solution on the inside of buildings. For this purpose, shorter ledgers are connected at the same height at 90° angles while using flights of stairs with smaller run lengths and heights. At the same time, the stairwell staircases serve as working platforms for carrying out further work on the sides of the walls. With standard components, access can be created to all floors in height increments of 25cm.

PERI UP Flex Stair 75 in action

  • Easily adapted for accessing building openings with brackets and small flights of stairs – regardless of storey heights.
    Highly flexible and versatile

    A system that can be configured to suit almost any building geometry and dimension.  Openings at different levels and varying storey heights are easily accommodated to provide safe access at all levels.

  • Flexible assembly through the 25 cm grid dimension, all bays can be completely closed even in the smallest of spaces.
    Easy assembly

    The the 25cm grid dimension of PERI UP ensures all bays can be completely closed even in the smallest of spaces.

    Short flights of stairs with 75cm widths offer maximum adaptability for small areas and narrow openings.

  • Fast installation with only a minimum number of ledgers and anchors.
    Rapid assembly and dismantling with no compromise to safety

    A minimum number of different component parts are required, nearly all with built-in safety features such as the PERI UP gravity lock.
