Abstract
A compression molded fiberglass reinforced resin grating formed of laterally spaced intersecting load bearing bars and cross bars is partially embedded within a layer of sand overlying the floor material of an animal stall defined by a vertical wall enclosure. At least the load bearing bars of the grating have flat top and bottom surfaces with opposite oblique sidewalls which taper towards each other from the bottom to the top. When embedded in the sand with the flat top surfaces exposed, the tapered load bearing bars resist downward movement into the sand layer due to the wider flat bottoms of the load bearing bars. Sand captured between opposed oppositely oblique walls of adjacent load bearing bars is solidly packed therebetween forming with the load bearing bars and the cross bars a solid mass to further resist downward movement, while permitting drainage of liquid waste therethrough. Soiled bedding may be removed from the top of the embedded grating by shoveling.
