A staircase consists of a flight of stairs with at least 3 successive steps. It serves to overcome differences in height in a comfortable and sure-footed way. Stairs and stringers are used indoors and outdoors. The underside can be either smooth, hand-smoothed or rolled. While the upper side can be formwork-smooth, textured, sandblasted or tiled, depending on the customer's requirements.

Platforms are two-dimensional prefabricated reinforced concrete elements. They are manufactured individually as well as shaped to fit a flight of stairs.
