A sliding gate, also known as a slide gate, is a type of gate that operates by sliding horizontally to open or close an entrance. Unlike swing gates that pivot on hinges to open inward or outward, sliding gates move along a track on the ground. The gate is typically supported by bottom wheels and guide rollers (Nylon ), allowing it to slide smoothly along the track .
