Boundaries on the water are not always easy to see. Deep-water areas, aquaculture sites, and construction zones need visible markers so people approaching them know where to take care. Our orange warning buoy, supplied with a solar-powered light, is designed to help identify and define these areas. Where can it be used, and what should you consider before ordering? Let’s explore this with SIAM Brothers Vietnam...

Several activities can take place on the same body of water. Boats may pass through while people approach the shore, aquaculture operators manage their sites, or construction teams work nearby. Unlike boundaries on land, the edges of these areas may have no visible fence or line.
A warning buoy provides a marker that people can recognize from the water or shore. Its orange body helps it stand out during the day, while the supplied light supports visibility when natural light fades. If you need to mark a long boundary or a large area, the number and positions of the buoys should be planned for the site. One buoy cannot show the full extent of an area from every direction.
A deep-water area, restricted-access zone, or location with a particular hazard may need a visible marker before people or vessels approach it. A buoy helps identify that location. Depending on the site, the operator may also need shore-based signs, operating instructions, and other appropriate measures.
Buoys can be placed at selected points around an aquaculture site, anchorage, or waterside structure to help identify its boundary. Before deciding how many to use, clarify whether you need to mark a single point, show a boundary, or separate several activity areas.
A warning buoy marks a location. It is not a floating trash barrier, nor is it a load-bearing float for a platform, raft, or floating dock.
Our warning buoy has a virgin LDPE body in orange. It measures 700 × 1,000 mm, weighs 11.3 kg, and has an 8 mm shell thickness. A solar-powered warning light is supplied with the buoy. These specifications describe this warning buoy model. If your project requires a different configuration, contact us before ordering.
The buoy body creates a visible marker on the water. Its orange color helps observers distinguish it from the surrounding environment under suitable daytime conditions. The solar-powered light supports identification after dark.
Actual visibility depends on buoy placement, weather, background lighting, and the direction of approach. If your project requires a specified light range, operating duration, or battery capacity, tell us so these details can be checked and confirmed before the configuration is finalized.

These specifications identify the product, but they do not determine the full installation plan. The number of buoys, fixing positions, changing water levels, and local wave and wind conditions also need to be considered.
Once placed and secured in a suitable position, the buoy acts as a visual marker for people on the water and on shore. When several buoys are used to define an area, their positions should make the boundary understandable from the usual directions of approach.
The buoy does not detect hazards or control vessel movement. Its fixing method needs to suit the current, waves, and water-level changes so that the marker remains in its intended position.
We supply warning buoys for marking locations that require attention, defining activity areas, and identifying waterside construction zones. The placement plan depends on the purpose and conditions of each site.

At a lake or another body of water with an area that people should avoid, a buoy can mark a location requiring attention. To indicate a longer boundary, consider the directions from which people and vessels are likely to approach when deciding how many buoys are needed and where to place them. Shore-based signs and site management procedures should also be considered.

Warning buoys can mark the perimeter of an aquaculture site, anchorage, or protected area around a structure. To help plan their placement, tell us the intended boundary, common vessel movements, and local water conditions.
If your project also needs floats to support fish cages, platforms, or floating docks, list those as separate items in your inquiry. Load-bearing floats and warning buoys serve different purposes.

During construction, buoys can help mark the work area or locations where people and vessels need to take care. If the work area changes, the operator should review the buoy layout and inspect the buoys throughout the project.
If the proposed location has specific waterway marking requirements, share the relevant requirements from the responsible authority or waterway operator with us before selecting a product. This buoy should not be assumed to meet every formal navigation marking requirement.
To request a suitable quote, contact SIAM Brothers Vietnam and tell us where the buoy will be used, what it needs to mark, and how many positions you need to identify. We can then discuss the product and scope of supply for your project. The quotation will depend on the quantity, accessories, delivery, and any requested support.
It helps to provide:
The location and purpose of the warning or marked area.
Site photos or video and the approximate area to be marked.
The number of marking points or estimated boundary length.
Information about currents, waves, changing water levels, and vessel traffic.
Any requirements for nighttime use, delivery, placement, or installation support.
Clear site information helps us discuss the quantity and scope of work. When reviewing a quote, check the product name, LDPE material, quantity, included light, delivery schedule, and warranty terms.
The warning buoy carries a 12-month warranty for defects caused by the manufacturer, starting from the invoice date. Damage caused by natural disasters, fire, careless use, unauthorized repairs, or minor wear from normal operation is outside the stated warranty coverage.
On delivery, check the quantity against the paperwork and inspect the buoy body, shell, and supplied light. Once the buoys are in use, regular checks of their position and condition can help identify changes caused by weather or activity at the site.
