Abstract
Abstract A wire mesh face mask for hockey or other sports is manufactured from a steel having carbon content in the range of AISI grades C-1018 to C-1038, and preferably C-1022. The mask is made by forming a grid of generally horizontal wires overlaid by generally vertical wires, shaping the grid into a mask shape, welding the wires to each other where they intersect, heat treating and quenching the grid to increase hardness, dipping the grid to coat it with an epoxy coating. This combination of materials and processes permits the use of a thinner wire than has previously been possible in face masks.
