Square Spiral Staircase fabricated using mild steel, galvanised and powder coated, with stainless steel handrail and mild steel, installed at Leeds West Yorkshire (05)
Summary of Terms Stairway, staircase, stairwell, flight of stairs or simply stairs are designed to bridge a large vertical distance by dividing it into smaller vertical distances, called steps.
Spiral stairs wind around a central pole. They typically have a handrail on the outer side only, and on the inner side just the central pole. A tight spiral stair with a central pole is very space efficient in the use of floor area.
Helical, helix or circular stairs have a handrail on both sides. These have the advantage of a more uniform tread width when compared to the spiral staircase. Such stairs can be built around an elliptical or oval platform.
