Straight stairs
Kiilax’s durable plywood protectors shield the mosaic surfaces of precast concrete stairs from wear, knocks, moisture and dirt during construction. The rigid protection helps prevent mechanical damage and reduce repair work.
The protectors are made to match the stair element and joined together during installation. The complete system is secured at the bottom and top of the stair flight, creating sturdy protection that is quick to fit.

Our standard protector fits 1,200 mm wide straight stairs without side beams, with vertical or sloping risers and a tread going of 300 mm. It also fits stairs with vertical risers, a tread going of 270 mm and a 20 mm nosing, as shown above. The installation order differs between these stair profiles. The rise can range from 110 to 190 mm.

To plan the stair protection, we need:
- Stair element width
- Tread going
- Rise
- Number of stair elements
- Number of risers per element
- Tread thickness
- Nosing or toe-space depth
- Side beam thickness, if present
If available, send us the stair manufacturer’s production drawings. They provide the best basis for designing the protection.
