SGS BV Marine Donut Fender For Port Great Quality China EVA Bumper

SGS BV Marine Donut Fender for Port Great Quality China EVA Bumper

Product Introduction

Jerryborg Donut fenders are a simple and versatile solution for berth corners, locks and similar applications.

Donut fenders float and rotate around a steel monopile. Their foam body provides buoyancy and energy absorption. The steel core has low friction UHMW-PE stave bearings so it moves freely with the rise and fall of the tide.

Low rolling resistance means Jerryborg Donut fenders are ideal for berth corners, lock entrances, guiding structures and anywhere that ships warp along the berth.

Submersible systems are also available for submarine docking operations.

Dimensions and Performance

Donuts are available in many other diameters and heights, different fender/pile ratios and to suit other pile diameters. Please ask for details. Standard tolerance ±15%. Table performance values are per 1000mm flat height. Performance is proportional to flat height. Performances are at deflections of 60% of Donut wall thickness.

Material

100% closed cell macromolecule elastic foam

They mainly are 100% closed cell EVA foam, according to targeted use. EVA foams are resilient, closed cells to avoid water absorption and are producted either by rolls or blocks. Those elements are glued or thermobounded to constitute monolithic cocon or core, then tooled to requested shape before being encapsulated by tough reinforced SPUA coating matrix as here under.

Technical reinforcement cord fabric

They are applied according to building rules of soft composites reinforcement to strengthen the “matrix” and constitute the encapsulating coating for Jerryborg’s fenders, buoys and floats, etc. The main reinforcement fabric in Jerryborg is 1480dtex/3 chinlon tyre cord, which is widely used in pneumatic fender and tire products.
