In order for the loads to be supported by the door fittings, reinforcement profiles are used. Normally they are closed profiles, usually square welded, which then receive the corresponding milling so that it is possible to house the closing mechanism. In this sense, the reinforcement profile with the Folding Concepta connecting plate is 2.6 m long. It is 65 mm high and 100 mm wide. It is made entirely of aluminum, with a matte anodized finish. The presentation in which it is packed is one unit.
