The buoys are primarily made of high molecular weight high density polyethylene (HMWHDPE) with a content of ≥ 95%, which provides excellent resistance to corrosion, frost, oxidation, and UV rays. Some models also utilize polyurethane foam, cross-linked copolymer foam, or composite foam to meet specific requirements.
The standard dimensions are 500mm×500mm×400mm. Depending on the configuration, the weight of the buoy is either 7 kg ± 0.2 kg or 6.5 kg ± 0.2 kg.
A standard 500mm×500mm×400mm buoy has a load-bearing capacity of up to 300 - 350 kg/㎡. Thanks to their seamless, one-time integral molding with a rated average wall thickness of 7mm, they have a service life of more than 15 years.
Yes, the surface features an anti-slip design, the four corners are shaped as rounded obtuse angles, and there are surrounding grooves to enhance stability, preventing shaking or tipping during use.
They are widely used for water traffic facilities (floating bridges, docks, boardwalks), water recreation (swimming pools, stages, bathing places), industrial and fishery projects (deepwater marine risers, cage aquaculture), and water conservancy projects (trashbuoys to block river debris).
