Wire mesh not only serves as a support structure for catalyst materials (e.g., Raney nickel, platinum, nickel-palladium) but can also be catalytically coated itself. This enables process-efficient solutions for the further treatment of hydrogen. Chemically stable special alloys like Inconel 600, Hastelloy C22, titanium, or nickel alloys ensure process stability, and individual forms such as pleated meshes, deep-drawn parts or precise cut-outs allow seamless integration.
