Wear Plate is quickly polished by abrading materials, producing a surface with a low coefficient of friction. This discourages hangs-ups, maintaining the efficiency of chutes, bins, hoppers, buckets and other material handling equipment. Wear Plate has a true weld-bead structure which produces a keyed-in interface of alloy and steel.
