The polyethylene buoy is rotated from UV-resistant polyethylene material, and the interior is filled with polyurethane foam and reinforced with stainless steel construction. The required color pigment should be injected into the polyethylene material before shaping. This extends the life of the buoy surface color and does not require painting.  when they are  compared with steel buoys, Polyethylene buoys are lighter and also have collision-proof properties. And because of its elastic properties, it can absorb impact forces and resist relatively stronger impacts. This buoy is also maintenance-free and has a longer service life.

Effects of polyethylene buoys:

Navigation markers are set in and near navigable waters to indicate waterways, anchorages, obstructions, shoals, etc., or as signs for positioning, turning, etc. Polyethylene buoys are also used to transmit signals, such as marking water depth, heralding styles, and directing traffic on narrow waterways. The location, characteristics, light quality, signals, etc. of the navigation signs are included in the navigation charts and nautical charts published by various countries. Modern polyethylene buoys are mainly divided into two types: marine buoys and inland buoys.

Application:

1. Anchorage, ship berthing, quarantine anchorage, no-sail zone, exercise area, etc.;

2. Offshore operation area, marine data detection, hydrographic survey, diving, salvage, offshore engineering construction work (drilling), marine development, mud throwing area, speed measuring field, compass correction field, water structures, cables, pipelines, inlets, outlets, etc.;

3. Split lane navigation, divider belt, etc., which can be used when using conventional navigational aids to indicate that the separation of lanes may cause confusion;

4. District, sports training area, sea, coastal bath, etc.;

5. Aquatic product operation area, aquatic fixed net operation area and breeding farm, etc.
