A channel section or pan for a scraper-chain conveyor has a floor plate welded between side walls. The floor plate has reduced thickness end regions which provide upper and lower tongues which establish joints with corresponding complementary tongues of the floor plates of adjacent pans. Each tongue has a prominent curvilinear profile in plan view with several smooth curved projections and depressions transverse of the floor plate.
