Precast winding staircase
Available in L or U shaped configurations, including winders at each turn. This type of stair eliminates the need for half landings. It can be easily installed as the building progresses using adjustable support brackets which are located in pre-designed openings in the stairwell.
The winding staircase offers inherent fire insulation and a high level of sound insulation, particularly when used in combination with Bison Precast floors at upper levels.
All standard stair components are manufactured in grey concrete using a manufacturing process that results in a finish to either soffit or the string that is not suitable for a direct paint or artex finish.
It is therefore recommended that where the string or soffit is exposed to view these surfaces are to be either plastered or dry lined. The standard detail for balustrades is to post fix on site to the stringer.
