Abstract
Anti-slip floor tiles are provided which are textured with a pattern of spikes. The spikes are preferably pyramidal or conical in shape. The height, angle, and base width of the spikes are important to slip resistance coefficients. Preferred spike dimensions range from about 0.2 to about 3.0 mm in height and from about 0.8 to about 3.0 mm in base width (or diameter). Further, a process for manufacturing an anti-slip floor tile which is textured with a pattern of spikes is provided. The tile is manufactured by pressing a powder on a mold, drying the resulting tile, and then firing the pressed tile at a high temperature. The surface texture is formed by the punch of the mold press which includes spike shaped indentations being the negative of the surface of the tile.
Claims22
