The Rigitra carcass consists of at least two plies of wholly synthetic Polyester-Nylon fabric (EP). EP-fabric is impervious to moisture and has low elongation and a very high tensile strength. Two extra plies of a special fabric (textile or steel) are also used to create the essential transverse rigidity. The choice of either textile or steel depends on the level of rigidity needed.
Rigitra cross-stabilized conveyor belts are custom made to order.
