Natural Rubber Dock Fenders Marine Fenders for Sea Boat

Product Description

 

Product Description

 
 Pneumatic rubber fender also called yokohama fender, made by rubber & multi layers of rubber-dipped tyre fabric, is a leading anti-collision device for marine application in the world today.
  Floating pneumatic rubber fenders can be easily handled and installed with guy-rope or guy-chain because of their lightweight. It can resist the shearing force and maintain energy absorption level under inclined compression up to 15 degrees. Meanwhile, provide low and comparatively even hull pressure. Consisted of several synthetic-cord layers and tough abrasion-resistant rubber, they have consistent performance even under rough conditions and cyclic load. The maintenance cost and damage risk are minimized too.The best material also ensures self-buoyancy and extremely long service life.
  Pneumatic fenders are available from 500 mm to 4,500 mm in diameters, and from 500 mm to 9,000 mm in length. All sizes of pneumatic rubber fenders are available as sling-type or with a heavy-duty chain & tire net. We also supply vertical hydro pneumatic fenders for submarines. Note: The floating pneumatic rubber fenders have sometimes been colloquially referred to as "Yokohama Fenders" or "Yokohama type fenders" - ISO 17357:2014 Ships and marine technology - High-pressure floating pneumatic rubber fenders.
