NORMAL
Normal is the basic version of the De Nardi overhead doors. The door frame is made with an exclusive reinforced steel profile designed to house the rubber sealing strip. A practical system of counterweights is inserted into the galvanized steel side uprights for easy, effortless opening. Metal parts are galvanized and painted on request with RAL colors and with stove-enamelled polyester-powder finish for maximum weatherproofing. The door is covered in okoumè wood multilayer panels on the outside with grout lines in different compositions. The overhead door Normal is lined on the inside, between the metal omega-shape bars, with plywood panels. The overhead door Normal may be supplied with a pedestrian door, glazed area and, for an even easier opening, with an electric motor. Normal is supplied with a Yale - type lock with handle, an anti-fall system and anchoring rag bolts.
