A furnace for the heat treatment of individual parts, in particular metal sheeting, which has a transport apparatus for conveying the parts to be treated through the furnace. This transport apparatus has two groups of longitudinal beams for supporting the parts, the beams lying alternatively adjacent one another in spaced relationship and at least one beam group of which being movable forwardly into a higher position than the other beam group along a partial stretch of the transport route and subsequently being movable back into its initial position into a lower position than this other beam group. A support structure supporting the beam and movable therewith is provided beneath each longitudinal beam, the support structure having at least one side surface extending continuously over the entire length of the supporting structure and facing the support structure of the adjacent longitudinal beam. In accordance with the invention, a tube is provided between two neighbouring support structures which also extends over the entire length of the support structures, the tube being expandable in cross section by filling this with a pneumatic or hydraulic pressurized substance and thus being able to be brought into tight engagement with the said side surface.
