Abstract: Roofing tiles have dimensions differing from conventional tiles to allow manufacture of the tiles in a substantially greater size than conventional tile sizes. The tiles may be installed more rapidly, since each piece of material must be separately installed and a single tile may cover a greater area. Additional ribs are added underneath the interior portion of each tile than with conventional tiles. The ribs are spaced appropriately such that a person walking over each tile would have the weight of a single foot distributed over one or more ribs at all times. Moreover, the rims of each tile extend substantially deeper, through the thickness, of the tile. Each tile has material removed from the main surface portion, or the actual surface opposite the weather-exposed surface, to reduce the weight therefrom. Each tile may be configured with open air channels underneath each tile up and down the entire roof.

Abstract: A method of forming and using a metal I-beam includes hot rolling an elongated metal workpiece to establish a web and a pair of flanges on the edges thereof. The web is formed with elongated reinforcement of solid cross-section having a generally straight longitudinal axis oriented generally parallel to the flanges. The hot rolled I-beam is cooled without forming substantial waves in the web and the I-beam is subsequently secured in a building construction or other structural product. The method involves the longitudinally oriented reinforcing means which preferably are one or more elongated laterally projecting ribs having such mass that the average temperature of the web prior to cooling will be sufficiently close to the average temperature of the flanges prior to cooling that the formation of waves within the web during cooling will be resisted. The reinforcement is preferably coextensive with the I-beam. The web is preferably substantially continuous.
