钢质浮标是航道上常用的助航设施，主要由灯架和浮体组成。根据布设水域不同有浅水浮标、深水浮标、大型海洋浮标之分。浮标规格一般按浮体直径区分，常用浮标有1.8米、2.4米、3.0米；大型浮标主要为5.0米、6.0米、10.0米。

浮标上可搭载航标灯、太阳能板、电池箱、顶标等航标器材。一般大型浮标作为助航设施的同时还可搭载其他大型设备用于海洋水文、气象监测等特殊场合。

浮标的制造符合《钢质海船入级与建造规范》、《材料与焊接规范》、《海区钢质浮标涂料配套体系及技术要求》、《海区钢质浮标涂装工艺要求》等标准。

Steel buoy is a kind of common navigation aids consisting of fixtures and floating body. There are shallow water buoy, deep-sea buoy and large ocean buoys according to different setting water areas. The size of buoys are differed according to the diameter of floating body. The common buoys have diameters of 1.8m, 2.4m or 3.0 m while large buoys can have diameters of 5.0m, 6.0m or 10.0m.

The buoys can carry navigation equipment like the beacon light, solar panel, battery box and top mark of AIDS. Usually, large buoy could be able to carry large equipment for special cases such as Marine hydrology and meteorology monitoring.

The production of buoys meets the requirements in Sea-going steel ships of the buoy manufacture conforms to the rules for the classification and construction , the material and the welding specification, the area supporting steel buoy coating system and technical requirements , sea steel buoy coating process requirements and other standards.
