Abstract:
A method of making a guide rail for an elevator system includes providing a metallic guide rail having a base portion and a blade portion extending from the base portion The blade portion includes one or more guide surfaces interactive with a safety brake of the elevator system. A protective layer is applied to the guide rail for corrosion protection and a perimeter of the protective layer is adhered to the guide rail to seal the guide surfaces from corrosive elements, while not adhering the protective layer to the guide surfaces.
