Rota manufactures non-metallic expansion joints that are used in utilities, steel mills, refineries, petrochemical plants, cement plants, pulp and paper mills, waste heat recovery and cogeneration facilities.

Non-metallic expansion joints are flexible connectors designed to provide stress relief in ducting systems by absorbing movement caused by thermal changes. They also act as vibration isolators, shock absorbers and in some instances to make up for minor misalignment of adjoining ducting or equipment.
