Automatic gate businesses supply, install and maintain powered gates for homes, commercial premises, farms and shared access roads. Systems may use sliding or swinging gates, with designs and materials such as metal, timber or composite. Installers assess the entrance, available space, ground conditions and expected use before fitting the gate, motor and supporting equipment. Some also provide manual gates or adapt existing gates for powered operation. Typical services include repairs, fault-finding, replacement motors and controls, and routine maintenance to check moving parts and electrical components. Access options can include remote controls, keypads, card or fob readers, intercoms and vehicle barriers. Safety equipment, such as photocells, pressure-sensitive edges and warning lights, may be fitted to help detect obstructions and alert people when a gate is moving.
