The new material buoy markers are made from linear low-density polyethylene or high molecular weight polyethylene. On one hand, through application comparison, we can identify the most suitable material and structure for our jurisdiction. On the other hand, these materials have stable performance and do not decompose or pollute water. Additionally, the buoy's color is derived from the raw material itself, eliminating the need for sandblasting and painting, which in turn avoids the pollution associated with painting.

By properly distributing inland waterway buoys, the direction, boundaries, and navigational hazards of the waterway can be marked, revealing relevant navigational information, and guiding ships along safe and cost-effective routes. Inland waterway buoys are categorized into three types: guidance for navigation, indication of hazards, and signaling. The shapes, colors, and lighting characteristics of the buoys are uniformly regulated according to the shore they serve (or background conditions).

White represents representation, protection, and guidance. White warning buoys are typically set up in harbors, docks, and other areas available for docking. The white buoys provide a stop for vessels, marking the area accessible through the pole.

That concludes the classification of colors for offshore warning buoys. By understanding the meanings of these colors, vessels can determine their course accordingly, ensuring safe navigation at sea.
