Maintenance free, aluminium sliding gate systems. All of our sliding gates are manufactured with an overhang, which has several purposes. The first is that it allows the support roller system (typically hidden behind the opening) to connect to the gate. It also is more aesthetically pleasing as you cannot see through the sides. When measuring for your new aluminium sliding gate, simply take the opening size as you normally would for a driveway gate (measure the clear opening). Included in our pricing, we have allowed for this 500mm overhang which is manfactured as part of the sliding gate. You only need to select the size bracket for your gap width, opening size. For example, if your gap/opening is 3.6m - we will manufacture the gate to be 4.1m. You would select the price/size bracket that has 3.6m within it.
