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.
