Buoys Comparative Analysis
Our Light Buoys are made of high density polyethylene (LLDPE) and are filled with special styrofoam (EPS).
Application of the rotational molding manufacturing method makes our buoys not only environmentally friendly, but also strong and lightweight with sophisticated body protection from hazardous effects of oil, gas, marine organisms, salt and fresh water and exposure to ultraviolet rays.
Materials: All buoys are manufactured using extruded polyethylene with a rotationally molded external shell. The inside is filled with freon-free polystyrene;
Wall thickness: from 5 mm to 18 mm;
Height: from 3000 mm to 7000 mm;
Diameter: from 160 mm to 1000 mm;
Weight: from 40 kg to 250 kg (depending on the model);
Ballast: from 22 kg to 200 kg;
Anchor: from 200 kg to 2000 kg (please refer to ………….).
Light Reflector: standard for all models
Radar Reflector: standard for all models
Life Cycle: up to 10 years
Warranty: 2 years
Quality Certificate: ISO 9001:2000.
Accreditation: all products are officially licensed by the Ministry of Defense and Ministry of Transport of the Russian Federation

Our polyethylene buoys are distinguished by their low weight, high density hence strength of the body and long lasting period of exploitation without having to replace due to corrosion or fading of color.
In comparison with metal buoys the polyethylene buoys do not require regular maintainance. The general checking of the buoys is carried out once in 3-5 years to control the state of the anchor chain; other things being equal the polyethylene buoy is not effected by hazardous weather conditions or salt water corrosion.
