2400 mm Low-Maintenance LLDPE Polyethylene Navigation Buoy for IALA Channel

The DX-PE2400A is a large polyethylene navigation buoy designed for projects that require dependable flotation without the regular repainting associated with a traditional steel float.

Its rotationally moulded LLDPE float, EPS foam filling and galvanized steel framework provide a practical platform for long-term navigation marking and future equipment upgrades.

The polyethylene float does not rust and does not require the same repainting schedule as a fully steel buoy. This makes the DX-PE2400A suitable for customers looking to reduce routine coating work and simplify long-term maintenance.

The upper frame and keel structure are manufactured from hot-dip galvanized Q235 carbon steel, combining a low-maintenance float with the strength required for lifting, mooring and equipment installation.

Product Structure and Dimensions

The 2400 mm LLDPE Marine Buoy DX-PE2400A can be supplied with a marine lantern and AIS AtoN, while RACON, remote monitoring, communication modules and selected environmental sensors can be evaluated according to project requirements.

Dexonmarine can coordinate:

•     Buoy structure and equipment layout
•     Marine lantern and AIS AtoN
•     Power supply and battery capacity
•     Communication and monitoring options
•     Mooring system requirements

Before production, Dexonmarine reviews the buoy structure, selected AtoN equipment, mounting interface, power supply and communication requirements as one system configuration. This helps confirm that the main components are properly matched before deployment.

The topmark helps identify the buoy’s function during daylight.

Dexonmarine can configure the buoy with the appropriate IALA topmark, colour and light characteristic for lateral, cardinal, special, isolated danger, safe water or emergency wreck marking, according to Region A or Region B and local authority requirements.

Dexonmarine 2400 mm LLDPE Polyethylene Navigation Buoy is suitable for:

•     Channel and waterway marking
•     Harbour and port approaches
•     Coastal navigation routes
•     Large navigation marks
•     AIS AtoN buoy systems
•     Monitoring-oriented buoy projects
•     Projects requiring future equipment expansion

Dexonmarine combines buoy manufacturing with marine lantern, AIS AtoN, RACON and remote-monitoring capabilities.

This allows the buoy structure, equipment layout, power system and communication configuration to be reviewed together instead of treating each component as a separate purchase.

Yes. Available colours include red, green, white and yellow. The final colour, topmark and light characteristic can be configured according to the required IALA buoy type, buoyage region and local authority requirements.

Yes. AIS AtoN and other communication equipment can be integrated after reviewing the required power supply, antenna position, payload and communication method.

Yes. The mooring chain, sinker and connection arrangement can be selected according to water depth, current, wave conditions, seabed conditions and buoy configuration.
