ABSTRACT:
An elongated flooring member includes an array of pyramid-shaped tread members to form an anti-skid surface. Longitudinally extending features of the flooring member are formed by an extrusion process which is followed by an embossing process to cut extruded flutes into the pyramid-shaped tread members. A first version of the flooring member includes a pair of channels extending downward from an upper web on which the tread is formed, for attachment to a substrate. A second version of the flooring member has an adhesive layer fastened under the upper web for attachment to a single plank.
