The OKTOSTAIR from Combisafe can be safely erected to a height of 62.4m (30 levels each 2.08m) without any special engineering measures. For heights greater than that, Combisafes Engineering Services can assist.
In all cases the height will be determned by the intended use and imposed load and the allowable leg load.
In all cases there are a maximum number of rise (16) per flight before a landing and two continuous flights in a line before a 90 deg change in direction.
Rise and going and width are controled by intended use.
