U-Shaped Profiles are machined as flats and then folded by thermo-line bending them to the desired shapes. Common uses are wire, tube, conduit, terminal block and bus bar covers that are electrical insulators to provide touch protection. Larger U-shaped parts are often used to make clear tunnels for the protection of conveyor and transfer belts in the food and pharmaceutical industries. Other uses are material chutes and bumpers made from softer materials to reduce wear and noise for example in coin sorting machines. Commonly materials are ABS, HDPE and clear PC.
