They are primarily made of high molecular weight high density polyethylene (HMWHDPE) with a content of ≥ 95%. Depending on specific application requirements, some buoys may also utilize polyurethane foam, cross-linked copolymer foam, or composite foam materials.
The standard dimensions are 500mm×500mm×400mm. Depending on the model specification, the weight of the buoy is either 7 kg ± 0.2 kg or 6.5 kg ± 0.2 kg.
A buoy of this size features a load-bearing capacity of up to 300 - 350 kg/㎡, which provides stable and secure support for various water facilities.
Due to their seamless, one-time integral molding design with a rated average wall thickness of 7mm (up to 11mm maximum), these buoys have a service life of more than 15 years.
Yes. The production process includes auxiliary materials such as antistatic agents, antioxidants, and UV-resistant agents. The product meets health standards, is pollution-free, and does not harm the surrounding ecological environment.
They are widely used in water traffic facilities (floating bridges, docks, boardwalks), water recreation (swimming pools, stages, platforms), industrial and fishery operations (marine risers protection, cage aquaculture support), and water conservancy projects (trashbuoys for blocking river debris).
