In the weaving process, the TOPGRATE® technology only uses, glass-fiber reinforced, PVC yarns of which an adhesion between the core and the skin > 20 N. The fabric, with a warp density of 12 threads/cm and a weft density of an average of 9 threads/cm, is stabilized in a heat set process. This wear layer is a phthalate-free plastisol laminated on a glassfiber fleece. The TOPGRATE® is finished, in a second step, with a homogeneous PVC backing.The rolls are available in a width of 2 m and a length, on request, between ca. 15 and ca. 30 lm.
