Abstract: The stairtread has the aesthetic appearance of a solid hardwood stairtread and presents a structural stability comparable to that of hardwood treads, but comprises a core layer made of lamellas of lower quality material glued laterally adjacent to each other. On the top surface of the core layer are glued laterally adjacent to each other top lamellas of higher quality wood. Underneath lamellas made of higher quality wood may also be glued laterally adjacent to each other on the bottom surface of the core layer to form a tread of which the underside is made of higher quality wood covering the lower quality core. Finally an elongate nose member is applied and glued to a longitudinal edge surface of the core layer. Use of lower quality material such as low quality wood helps to preserve our natural resources and to reduce consumption of higher quality wood material becoming every day more rare and difficult to obtain.

Abstract: A method of manufacturing a two-color non-slip tread or flooring plate includes the steps of dimensioning the plate, cleaning the plate and applying a bonding agent to the plate. A uniform layer of plastisol of a light color, containing gritty particles such as aluminum oxide, is sprayed on one of the surfaces of the plate or tread. After partial curing by baking, a masking material is applied along one of the edges. This edge is selected to be the edge which would abut a discontinuity in the floor such as the edge of a step or a flooring area which is raised. A second layer of plastisol containing gritty particles with a darker pigment is then sprayed on to the first layer of plastisol. The plastisol layers are then cured by baking and the masking material is removed. The invention includes tread plates and flooring plates made in accordance with the method of the present invention.
