General Surface Chain Support Buoys
6Pages

GENERAL SURFACE BUOYS General surface buoys are constructed by resilient closed cell polyethylene /EVA foam around the inner central steelwork, covered by polyurethane (PU) outer kin. General surface support buoys are extensively used in single-point mooring (SPM) systems. The resilient closed cell polyethylene/EVA foam core guarantees selffendering and unsinkable even in case of damage. The foam core is encapsulated within a skin of tough, abrasion resistant polyurethane elastomer applied by our well proven spray technique. The polyurethane elastomer skin is high resistance to abrasion, fatigue and ultra-violet degradation together with excellent resilience. It does not attract marine growth. For extreme operating conditions, the PU skin can be reinforced by polyester material during the spray process as reinforcement to add further strength. Un-skinable closed cell rigid foam core PU Protective outer skin Self-fendering with high impact absorption capacity Various end fitting options available Polyester reinforced skin with better performance Internal steel core for better support and balance Various color for choose Customized size and shape available The self colored skin can be supplied in orange, yellow, red, black, naval grey for easy of identification. General surface support buoys have a flotation core manufactured from resilient closed cell polyethylene or EVA foam around internal steelwork. The closed foam ensure the buoy will not absorb water even if the skin is punctured, increasing the life-span of the product and reducing maintenance costs. The resilient foam core makes the buoys self-fendering with a high impact absorption capacity. www.doowinmarine.com - sales@doowinmarine.com
