Buoys Comparative Analysis

General Description

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.

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.
