Rolls weighing between 80 and 100 kilograms are expected, supplied with springs designed to lift shutters so that they can guarantee repeatable performance for each size. What makes these springs particularly reliable is their constant lifting capacity over their long expected life span. In fact, when they are correctly sized and installed, no breakages occur during assembly, and the life of the hardened steel springs significantly exceeds that of the other components of the shutters. It is important to underline that over time the hardened steel spring does not show any deterioration in performance.
