Abstract
Monolithic carrier matrixes are formed from high grade steel, consisting of alternating smooth and corrugated layers of sheet metal and/or screen cloth, which may be combined with layers of smooth screen cloth or of smooth or corrugated sheet metal, wherein the layers may be coated on their surfaces with a catalysis-promoting carrier material. These carrier matrixes may be used to produce catalysts for the purification of exhaust gases.
