Abstract
A metal patio chair has a seat frame made by the steps of providing a pair of seat rails in the form of elongated metal tubes, placing a mandrel inside each tube to reinforce the wall of the tube, punching a series of spaced apart holes in the wall of the tube while the mandrel contained in the tube holds the shape of the tube while punching out the holes, removing the mandrel, providing a plurality of metal slats having a cross-sectional shape to match the shape of the holes punched in the seat rail tubes, inserting ends of the metal slats in corresponding pairs of holes formed in the tubes to form a ladder type chair frame in which opposite ends of the slats are held captive in corresponding holes in the tubes, and are rigidly securing the slats to the seat rail tubes to lock the slats in palce in the tubes to provide a rigid seat frame structure elevated above the ground by a supporting sub-structure to which the finished seat frame is attached.
