Designed for year-round deployment, the buoy maintains stable performance under waves, currents, and changing weather conditions.
The internal closed-cell foam prevents loss of buoyancy and helps ensure continuous operation even if the outer shell is damaged.
The rotomolded outer body offers excellent resistance to UV exposure, seawater corrosion, and mechanical wear.
Compared with traditional steel alternatives, the buoy is significantly lighter, making transportation and installation more efficient.

Polyethylene Mooring Buoys are suitable for vessel berthing systems, marina management, offshore support operations, anchorage zones, floating pontoons, and coastal infrastructure projects. They are commonly used to secure fishing vessels, passenger boats, yachts, tugboats, service craft, and floating work platforms. Their durability makes them particularly valuable in locations where maintenance access is limited.
These buoys are widely used across commercial ports, yacht marinas, offshore energy developments, marine construction projects, fish farming operations, coastal transportation systems, and government maritime facilities. They are also increasingly selected for environmentally sensitive waterways where corrosion-free and recyclable materials are preferred.
A1: Under normal marine conditions, the expected service life ranges from 15 to 30 years depending on the operating environment and maintenance practices.
A2: Yes. The reinforced internal structure and foam-filled design allow the buoy to perform reliably in both coastal and offshore locations.
A3: No. Unlike steel buoys, polyethylene buoys do not require anti-corrosion painting or rust treatment.
A4: Yes. Custom dimensions, buoyancy ratings, colors, and connection hardware can be manufactured according to project specifications.
A5: We provide heavy-duty hot-dip galvanized steel or marine-grade stainless steel connection components, ensuring high tensile strength and long-term corrosion resistance.
A6: The interior is completely filled with high-density closed-cell polyurethane foam, which prevents water ingress and ensures that the buoy retains full buoyancy even in case of outer shell damage.
