Marine Dock Square Rubber Fenders High Energy Absorption Pier Dock Berth Vessel
Description
Square rubber fenders are widely used as belts on tugboats and other workboats. The fender has a round hole to increase wall thickness and durability. The square fender has similar advantages to the D fender. Compared with the D fender, the square rubber fender is used for harder and stronger collisions under harsher conditions. Compared with cylindrical fenders, they have suitable reaction forces and higher energy absorption.
Square rubber fenders are simple rubber profiles, usually bolted to the structure. Extrusion molding can be made to virtually any length and then cut and drilled according to the requirements of each application. The square fender is applicable for all kinds of docks, quays, and ships. Good performance during angle berthing.
