The lightweight aluminium flights of stairs with 75 cm widths are mounted on ledgers of the PERI UP modular scaffolding. This results in 4-legged stair towers with alternating staircase units or staircase units in the same direction with heights of up to 100 m. The PERI UP Flex Stair 75 is designed to accommodate 2.00 kN/m² loads and serves as access to working areas or construction sites.
Through the 25 cm grid dimension, all bays can be completely closed even in the smallest of spaces
for accessing building openings with brackets and small flights of stairs – regardless of storey heights
with only a minimum number of ledgers and anchors
With the stairwell staircases, compact access means can be provided on the inside of buildings with small staircase wells. For this, 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 25 cm.
