Offshore and coastal steel is strongly affected by salt and humidity, and corrosion is a serious problem, causing huge losses every year. It is an important content to analyze the main protective measures and effects against corrosion of steel structure parts in China, and to understand the anticorrosion mechanism of various technologies, so as to further improve the anticorrosion effect and cooperate with the implementation of China s marine strategy. This paper mainly analyzes the protection mechanism, anticorrosive effect, economic benefit and environmental benefit of different anticorrosive measures, summarizes the advantages and disadvantages of different anticorrosive measures, and puts forward that a single anticorrosive measure is difficult to meet the requirement of long-term anticorrosive effect, and multiple effective methods should be adopted to improve the anticorrosive effect. The development prospect of anticorrosion technology for steel structure parts in marine environment in China is prospected.
