Abstract

Railings for fencing comprise hollow metal tubes, preferably polygonal covered with polyvinylchloride or other synthetic resin. The resin is moulded over the tube by extrusion (see Group V) and is formed with longitudinally extending ribs or fins. The metal core may include parts to take screws or nails.
