Production of spiral staircases
Spiral staircases are used as auxiliary staircases, whose advantage is their small floor plan area. The staircases are supplied as a modular system.
The Lichtgitter range includes staircases in two versions:
- “LG Special” staircase
- “LG Standard” staircase
Both types are characterized by easy installation carried out according to the supplied technical documentation.
The staircase is designed for a uniformly distributed load of 3.0 kN/m2, or for a concentrated load of 2.0 kN applied to a load area of 100×100 mm, located at the nosing edge, 100 mm from the outer edge of the stair tread.
Staircase structural material:
- steel S 235 JR
Surface finish of staircases:
- hot-dip galvanizing according to ČSN EN ISO 1461
