We feature another Expanded Metal Grating called Projection Mesh. Projection Mesh Expanded Metal Safety Grating features small tooth-like projections on the upper surface of the mesh. These projections provide an excellent non-slip surface where additional anti-skid surfacing is desired. Projection Mesh Expanded Metal Grating is available in carbon steel in 2 and 3 pounds per square foot and in aluminum a 1 pound per square foot.
