General Information

CONIDUR® hole sheets are sheets with special shaped holes. The upper and lower side of the CONIDUR® hole sheet have different characteristics. The special manufacturing process enables the finest perforations in initial sheet thicknesses, which can be a multiple of the hole diameter. Through cold forming, the CONIDUR® hole sheets indicate very good wear resistance, which can be improved further through surface treatment if required.
