rubber ship fender (near the ball) is made of rubberized cord fabric, filled into the compressed air, The fender body is covered by a chain net, wire net or fiber net. Chain nets are able to withstand corrosion longer and are usually built with used tyres and rubber sleeves to provide additional protection. Fiber nets use only rubber sleeves. Wire nets are light and more easily repaired.
  you can hang it on the side of the ship or pier to slow the ship and between ships, reduce the impact between the pier and ships. Because of its high energy absorption, impact resistance and other advantages,it has become a necessary protection of the ship and port facilities.

They are use compressed air as a buffer medium, which prevent ships from being collided strongly when they land. compared with ordinary elastic rubber fenders(like discarded tires, solid rubber fenders and so on), it has more advantages such as absorbing impact more effectively. Low unit pressure on ships, the function of fatigue-resistant is excellent and easy install.

  They are widely used in large oil tankers, liquefied gas ships, offshore platforms, large-scale docks, sea port and quay.
