Why do prefinished solid wood floors have a micro-bevel?
The purpose of taking the edge off of the corners of the surface of most solid prefinished wood floors is to forgive any slight deviations in the milling or in the sub-floor that might situate an individual piece of flooring slightly thicker than the adjacent piece. In a site finished wood floor any tiny differences are sanded smooth. Taking the crisp edge off of the corners of hardwood is routine in furniture manufacture. Since the precision of wood flooring manufacturing equipment keeps improving, the old “v-groove” in prefinished flooring has been reduced to mini micro-bevel.
