Spiral Staircase for Escape and Industry
Weland spiral staircase for escape and industry are manufactured with treads of grating or durbar plate. These staircases are applicable for escape purposes for all types of rooms. They are also applied in industrial and storage rooms, silo constructions, water towers, pump stations etc.
Weland spiral staircases for evacuation and industry are as standard hot dip galvanized in accordance with class SS-EN ISO 1461.
Spiral staircases in many cases blend well with their surroundings as a part of the façade.
Spiral staircases require the same small base irrespective of how high they are. They can be manufactured left turning or right turning and have a different number of treads per revolution. This means that, as a rule, you can always achieve an efficient staircase.
Spiral staircases normally do not demand extra load carrying constructions provided the landings are not excessively large.
A spiral staircase with a radius of 900 mm and a radius adapted stepping-off landing sized 950 x 950 mm requires a well space of diam. 1900 mm.
Can be constructed to great height
Spiral staircases can be built very high without any extra supports, provided bracing can be arranged, for instance against a wall. If there is no adjacent wall, bracing can be carried out with vertical support legs outside the staircase circumference.
If a person looses balance on a spiral staircase, they are more likely to fall against the balustrade thereby checking their fall and giving them the chance to grab the railing or the newel post.
Since spiral staircases are comfortable to descend, an escape can be carried out quickly. Even rescue on a stretcher can be carried out comfortably.
Easy to erect
The spiral staircase is supplied in knock-down components for assembly on site. The only tools required are a drilling machine, a spanner (either fixed or ratched) and an Allen wrench.
