TYPE SW-HE (STRAIGHT WARP WITH HIGH ELONGATION WEFT CORDS)

SW-HE conveyor belts, having a steel cable mesh, are impact resistant and can be used in a temperature range of -25˚C…max 150ºC. Special steel cords are used to give an adequate behavior at compression, a favorable elongation and a good tearing resistance. They are used for elevators and for installations which require more protection underneath the belt.
