Product Description
The DX-ST3000 is a large steel navigation buoy designed for demanding marine marking applications where structural strength, stability and long-term durability are required.
Built with a CCSB marine steel float body, welded construction and protected steel components, the buoy provides a robust platform for navigation equipment in challenging offshore and coastal environments.
Its four sealed compartment design, corrosion protection system and practical maintenance access support reliable operation during long-term marine deployment.
3000 mm Steel Float · Sealed Compartment Design · Corrosion Protection System · Stable Ballast Arrangement · Marine Equipment Support
The DX-ST3000 uses CCSB marine steel construction and a welded structure to provide the strength required for large navigation buoy applications.
The four sealed compartment design helps maintain buoyancy reliability, while the cast iron ballast system supports stable floating performance and navigation marking accuracy.
Hot-dip galvanized components, protective coatings and sacrificial zinc anodes improve corrosion resistance for long-term marine service.
The maintenance hatch provides convenient access for inspection and servicing, helping simplify routine maintenance operations.
The DX-ST3000 supports installation of marine lanterns, topmarks, radar reflectors and other navigation equipment according to project requirements.
Configured for the Required IALA Mark
The topmark helps identify the buoy’s function during daylight.
Dexonmarine can configure the buoy with the appropriate IALA topmark, colour, and light characteristics for lateral, cardinal, special, isolated danger, safe water, or emergency wreck marking, according to Region A or Region B and local authority requirements.
