<p>A panelling system preferably for floors is defined by a series of panels each formed of a plurality of tongue and groove main floor plank strips arranged side edge to side edge and cut to a common length with a tongue along one cut edge and a groove along the other. At the edges are attached edge strips formed also from the flooring planks with tongue and groove and fastened together to form a common panel member for transportation and installation. The outwardly facing edge has a tongue or groove for mating with a groove or tongue of a next adjacent panel. The strips are fastened by pins or corrugated plates from the rear or by a bonded sheet material on the rear. The strips may include tongue and groove joints of the snap fastening type where the connection of each strip to the next in the assembled panel can be by adhesive tape over the rear surface of the snap fastening joint. A decking arrangement uses grooves in the side surface of the planks fastened together by intervening inserts.</p>
