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 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.
