FIELD: transport facilities for waste gas catalyst carrier. SUBSTANCE: metal member includes sheet layers 3 and 4 which are cross-linked at least partially; these layers are bent in form of involute; member in outer circular zone 6 and inner circular zone 5 has at least three return lines (2a, 2, 2c.... corresponding to 7a, 7, 7c,...) around which sheet layers 3 and 4 are interlaced; direction of curvature changes from outside to inside. Such member may be manufactures from hollow roll through star-shaped deformation followed by interlacing of outer portion around inner portion; that is why, it is preferable from the standpoint of manufacture. Long electric conductor performing the function of heating element or measuring sensor may be built in. EFFECT: enhanced efficiency. 18 cl, 23 dwg
