Stairways are, in general, a thoroughly studied subject, but there is almost no scientific data available about spiral stairs. They are, however, widely used in homes, industrial sites and public buildings. The purpose of this study was to determine preferred handrail heights for a spiral ...
Maximum back slope on open riser stairs: Open riser stairs are allowed a back slope of at most 1 1/2. If stair treads are constructed so that the front edge of a tread is more than 1 1/2" behind the back edge of the stair tread below, the treads can become a trip hazard. ...
