A plurality of stepchain links ( 30, 130, 230 ) of a passenger conveyor system ( 20 ) connected to form a continuous loop are from die cast or from stamped or laser cut metal. Each stepchain link ( 30, 130, 230 ) includes a plurality of teeth ( 32, 132, 232 ) made of a single piece of material that engage a drive member ( 36 ). In one example, a plate of injection molded plastic teeth ( 294 ) are snapped onto the links to reduce corrosion. |
