The buoys are usually made of high molecular weight high density polyethylene (HMWHDPE) with a content of ≥ 95%. Some buoys may also utilize polyurethane foam, cross-linked copolymer foam, or composite foam materials to meet specific requirements.
The buoys come in specifications of 500mm×500mm×400mm, with weights available at either 7 kg ± 0.2 kg or 6.5 kg ± 0.2 kg depending on the specific model configuration.
A buoy with a size of 500mm×500mm×400mm has a load-bearing capacity of up to 300 - 350 kg/㎡, providing highly stable support for various water facilities.
The buoys are integrally formed at one time and are completely seamless. With an average wall thickness of 7mm (up to 11mm maximum), they have an expected service life of more than 15 years.
They are widely used in Water Traffic Facilities (floating bridges/docks), Water Recreation (swimming pools/stages), Industry and Fisheries (marine risers/cage aquaculture), and Water Conservancy Projects (trashbuoys for flood garbage blocking).
