Carriages for cantilever 30x30 are made of long-lasting and resistant materials, which makes them very durable. The gate rollers are galvanized and protected from corrosion. They are available in two-, three-, five-, eight- and ten-roller sets with mounted bearings. The carriages available are equipped with plastic or steel rollers. Such rollers are suitable to be used in underslung elements, gates or rail doors. A horizontal plastic roller acts as a guide roller, while vertical rollers are support rollers. A plastic roller, commonly coming in white, gets abraded 30% more than a metal one. Precisely-made and accurately-assembled items ensure no deflection of the gate. The base of a carriage has four longitudinal holes enabling its adjustment. A carriage is assembled by being welded or screwed to a metal structure, depending, on the carriage type. The following types of gate carriages are available: steady carriages, height adjustable carriages, self-aligning carriages, self-aligning and adjustable carriages as well as carriages with a flat bar.
