Handrail
Grip rail on the railing or along the wall of a stair flight.
The handrail is the grip rail on which users hold themselves while climbing stairs. It runs parallel to the stair flight and can either be mounted directly on a wall (wall handrail) or form part of the railing. DIN 18065 requires at least one handrail; DIN 18040 for accessible construction demands handrails on both sides extending 30 cm beyond the flight.
