Spherical Buoys provide exceptionally reliable buoyancy for a variety of oceanographic, commercial, military and offshore applications. Spherical buoys come in a range of diameters and volumes-finding the right one depends on your requirements.
Spherical Buoys are constructed by resilient closed cell polyethylene foam around the inner central steelwork, and constructed of tough and thick nylon filament reinforced polyurethane skin, which provides unsurpassed strength. The resilient closed cell polyethylene foam core guarantees self-fendering and is unsinkable even in case of damage. And self-colored polyurethane elastomer skin is resistant to abrasion and ultraviolet ray degradation.
