PCT No. PCT/NL94/00321 Sec. 371 Date Jun. 21, 1996 Sec. 102(e) Date Jun. 21, 1996 PCT Filed Dec. 16, 1994 PCT Pub. No. WO95/17534 PCT Pub. Date Jun. 29, 1995A screen material is described which is formed by cladding, using electroplating, a structure composed of strands or fibers. The structure may incorporate a knit, woven or nonwoven material or, alternatively, of strands or fibres welded together, wound strands or fibers. The structure may be subjected to a calendering operation. The screen material, after having been provided, if required, with an electrically conductive cladding, is provided with a metal layer in an electroplating operation under conditions in which an overgrowth ratio R greater than 1 is achieved. The invention also describes a method for manufacturing such a screen material which preferably involves making use of an electroplating bath for depositing a metal cladding on a starting material in which a chemical compound is present which increases the overgrowth ratio R. The method can be implemented using a variety of conditions which can lead to an overgrowth ratio R of a desired value.
