Century Fence offers an Aluminum Cantilever Slide Gate that is maintenance free. It is manufactured from rust free aluminum. This gate will never require painting. The roller trucks which contain sealed bearings don't require grease. Concealing the truck inside the track eliminates maintenance problems caused by sand, snow, ice, or the inability of the gate to slide because the bottom exposed roller has slipped to the ground. In addition, the ease of operation from the reduced weight of the aluminum components means you'll probably have more trouble with your padlock than the gate.
