Semicircle (D) type rubber fender belongs to extruded fender, which is a simple rubber profile. It is mainly used in frame type wharf and upper revetment of wharf.
The D-type rubber fender produced by SUNHELM is designed to have a large compression deformation (in the case of no increase in reaction force), which is 20% higher than the V-type rubber fender and 8% higher than the M-type rubber fender, so that the energy absorption of the D-type rubber fender is greatly increased, and the structure is usually connected by bolts.
