Norfloat International’s range of navigation buoys are manufactured in-house, and have been designed to provide a reliable cost effective and stable platform suitable for most makes of self-contained LED light units.  The buoys are rotationally moulded using ultra-violet stabilised virgin polyethylene providing a colour fast life of up to 10 years and excellent impact resistance.  The low energy surface properties of polyethylene reduce marine growth significantly which helps to keep maintenance costs to a minimum.  In the unfortunate event of collision, the NN range of buoys are pressure foam filled to a density of 34 kg/m3 making them virtually unsinkable.
