EVA Foam Donut Fender Floating Marine Boat Fenders SPUA Coated For Steel Pole

EVA Foam Filled SPUA Coated Floating Donut Fenders for Steel Pole

Donut Fender is a specific type of Foam Fenders. It is designed to simply slip over a stationary monopile. Due to its construction, the fender floats up and down with the fluctuating water levels and rotates when vessels berth and slide along the fender. The Donut Fender is designed with a 100% closed cell cross-linked polyethylene foam core, a reinforced elastomeric skin and low friction pads at the internal steel core.

Donut Fenders are available in diameters from 1,270 mm to 4,220 mm and a maximum pile diameter of 610 mm to 2,388 mm. Additionally, mooring crowns, counterweights (for sub-marine applications) or other features like protective nettings can be added.

The foam hardness, skin thickness, pile/fender diameter and also the height of the fender can be changed on request. ShibataFenderTeam would be pleased to receive your design input allowing us to engineer the correct type, size and overall layout of the Donut Fender.
