Date Jun. 6, 1996A metal support for exhaust gas cleaning has a metal honeycomb core body fabricated by laying a planar sheet on a corrugated sheet and rolling the laminated sheets into a cylindrical configuration. The corrugated sheet has sinusoidal shaped portions having a wave height which is sufficient to contact the adjacent planar sheet and square wave portions which have a wave height which is insufficient to enable contact with the adjacent sheets. The square wave portions have corners which project out beyond the sinusoidal shaped portions and produce agitation and disturb the flow of gas and to induce an increase in the contact efficiency between the gas and surfaces carrying catalytic material. The planar sheet is not limited to continuously flat sheets and can include flat surfaces formed by zigzag or square wave shaped members. These members can be perforate and or made of a mesh material.
