Abstract: A guide rail for an elevator car in a hoistway includes a base connectable with a wall of the hoistway. A web portion is connected to and extends from the base to a rail tip. The web portion includes a closed cross-section defining a web cavity extending along a length of the guide rail. The closed cross-section is formed of a sheet metal material to improve the torsional stiffness of the rail. A filler strip is located in the closed web cavity to prevent damage to the closed cross-section under braking forces applied to the guide rail.
