Help with Solution-Finding

Our experience shows that in the case of spiral staircases it is often very difficult during the planning phase to find the location of the stairhead landing relative to the position of the first step. It is possible for the spiral staircase to be left or right-handed or to be produced with different circle graduations. The selection of the appropriate circle graduation depends on various factors. These can be the required minimum tread on the inner border in the case of spiral steps of 100 mm, the clear stair headroom of 2,000 mm, the pitch ratio of 2 s + a or the arrangement of the platforms.

The desired tread widths can be achieved for the diameters shown by means of various subdivisions. The following can be recommended as a fundamental rule: small diameter = fewer subdivisions and large diameter = more subdivisions.

Smaller stair diameters can only be used in situations where space is limited on the building site and in coordination with and with the approval of the local building supervisory authorities. For the non-public or private area it is possible to use smaller stair diameters.

The production range of the MEISER spiral staircases comprises a diameter from 1,200 to 4,000 mm and depends on the desired requirements as well as the structural conditions.
