A support frame for metal coils, which are stacked on top of each other for a heat treatment by means of a hot, gaseous medium, especially in bell-type annealing furnaces, has devices on the support frame for guiding the flow of the medium through the coils. The support frame is a framework constructed of I-sections. The end surfaces of the coils are supported on the flanges of the framework I-sections. The webs of the framework I-sections are provided with holes, which serve for guiding the flow of medium.
