The upper surface of the impact bars is produced from Polyethylene 1000 (UHMW) material, which can show high resistance to abrasion and has low friction coefficient. On the lower layer, there is a shockabsorbing epidermis rubber and an aluminum slide for easy assembly. The  structure of the bedding system is very important in order for the impact bars to be used for a long time. With its solid steel construction and adjustable structure, the bedding systems allow the use of long lasting products. The whole system is supported by PU 80 springs at 4 points in order to absorb the incoming load. Bedding systems are manufactured in accordance with spilled materials, gutter structure and return path standards.
