A harp staircase is a staircase that has ropes or a grid made of a suitable material (e.g. steel ) in the stairwell or on its light side . The name is based on the association of this part with the strings of a harp . The steps can, but do not have to, be carried by the ropes or the grating.
If the harp section is designed as a grid, it can serve as a static element in which it transfers the weight of the stairs including the traffic load to the floor. Since this contributes to the static stability, it is possible to make the spars that support the steps more filigree. The harp is carried out vertically and usually in a closed lattice form, in contrast to a rising railing , from the bottom to the top floor of the staircase.
In addition, the harp serves as a fall protection instead of a rising railing. A handrail can be attached to the harp as well as to the outside walls of the stairwell.
Like other stairs, the harp staircase also offers individual design options.
