Conveyed material will adhere more readily to steel rollers and will create an uneven and imbalanced surface, resulting in improper belt tracking and conveyed substance spillage.
Also, steel rollers suffer from the adverse effects of rust and corrosion from high moisture/high humidity environments. This rust and corrosion lead to belt failure from damaged rollers. These negative effects force steel rollers to be replaced much sooner than HDPE rollers, resulting in more down time, less productivity and higher overall costs. HDPE rollers do not rust or corrode from use in or near wet conditions and therefore last longer than their steel counterparts.
