A mesh panel of the type having a plurality of spaced apart apertures includes an internal frame member substantially in the form of a perforated sheet, and having a plurality of openings therein larger than the apertures. The frame member has substantial internal rigidity. An elastomeric coating encapsulates at least a portion of said frame member. In a preferred embodiment, a bonding coating between the elastomeric coating and the frame member securely bonds to both the elastomeric coating and the frame member. The bonding coating is of the type that is liquid before application to the frame member and is curable by heat or time to a hard plastic. Preferably, the bonding coating is partially cured before the elastomeric coating is applied, after which both coatings are cured by heat. The panel is particularly well suited for use as a sorting screen.
