Abstract
Nailable flooring is constructed of identical floor units having roll-formed therein closed bottom nailing grooves of serpentine contour for the retention of nail fasteners held in place as they are deformed upon insertion into the grooves. The grooves are disposed between opposite side edges of the units and/or mating portions of such grooves are roll-formed along such side edges. The bottoms of the grooves are substantially triangular in cross-section thereby negating the crippling effect of each groove structure which thereby functions similarly to that of a beam web.
