In coastal environments, steel structures corrode extremely rapidly, thus requiring very specific corrosion protection measures. This is mainly reflected in the need for more stringent corrosion protection design levels, thicker coating systems, and more stringent construction and acceptance standards.

Environmental Classification: Accurately determine the C5 or CX level according to ISO 12944.
System Selection: Select a heavy-duty anti-corrosion coating system with a total dry film thickness of at least 280μm.
Reinforcement of Critical Components: For ultra-long service life or underwater structures, employ composite measures such as thermal spraying of metal or cathodic protection.
Strict Construction and Acceptance Control: Strictly adhere to Sa 2.5 grade surface treatment and coating quality testing.

The final solution must be determined comprehensively based on factors such as the specific structural type, design life, and construction conditions.
