Sliding & Telescopic Gates
 
Sliding Gates
These have the advantages of saving space, having long-term reliability and having cheaper and more simple motors. In many instances swinging is the only option. Gates can be swung both inwards and outwards. Swinging gates have the advantage of speed when operating.
 
 
Telescopic Gates
These are automatic sliding gates that move in parallel and concertina in the closed position at one side. You only need a bit more than half of your driveway distance as a recess to install them. SAS Autogate, an Australian innovation, have invented Telemech (as seen on ?The New Inventors?), which is the mechanism that enable this system to not only function well, but also be aesthetically pleasing.
