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

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.
