Manufacturer Good Sale Pneumatic Rubber Fenders, Rubber, Rubber Fenders

Qingdao Manufacturer High Quality Good Sale Rubber Fenders



Characteristic:

Pneumatic rubber fenders use compressed air as buffering medium to absorb the impact energy of the ships. They feature good resilience, high energy absorption, perfect angular compression performance, and convenient portability; Therefore they are widely used at large offshore terminals and floating docks without good STS or STD berthing conditions.
