SBR (Styrene Butadiene Rubber) is the most commonly used handrail cover material. DS SBR Handrails have a glossy black surface and stable shape dimensions. A protective coating of anti-aging additives diffuse into the surface of SBR handrails, protecting against dynamic stress, heat aging, and ozone found in the ambient air. The disadvantages of these additives include the discoloration of materials touching the protective film and the sticky surface caused by the anti-aging wax.Model SpecificationsThe following diagrams are DS's recommended handrail designs, C-type and V-type handrails. A properly functioning and fitted handrail must have appropriate interplay between the guide element and drive mechanism of the escalator. The most important design dimensions are the inner width (B), inner height (E) and the lip width (A). The following cross-sectional diagrams and tables provide references for the appropriate values necessary for your system. Alternate designs should be discussed with DS technicians on a case-by-case basis. url:
