Poralu Marine is not only an aluminium floating pontoon specialist! We can offer a complete range of fixed pontoons or board walks where suitable. Modules: 1 to 6 metres in length with a load capacity of between 200 and 500 kg/m2. Span length between supports can be configured to reduce piling costs.
The Donut system uses a floating ring-shaped fender which rises and falls with the water level on a central steel pile, guided by low-friction pads. The Donut system’s ability to rotate helps reduce shear forces in both fender and dolphin and allows vessels to move fore and aft (warp) along the fender.
