Marine Fenders Pad is made from UHMW-PE (Ultra High Molecular Weight Polyethylene) which has been used for years by marine manufacturers worldwide.  It’s an extremely durable material They're usually fixed to the panel using stainless steel screws that are screwed into the skin of the steel panels.  Ultra-high molecular weight polyethylene (UHMW-PE) provides a smooth surface for vessels to dock against. 

Key benefits:
UHMWPE Marine Fenders Facing Pad provide the benefits of higher wear resistance (even greater than steel) and lower maintenance; as they do not split or rot and are fully resistant to infestation from marine borers. 
The low friction coefficient and high abrasion resistance of UHMW-PE provides an ultra smooth surface for the vessel to slide easily along the face of the fenders.
