Coating System for Gates

Gates, as critical components of water conservancy facilities and transportation systems, are widely used in dams, bridges, and power stations along rivers and estuaries. Their anti-corrosion design must account for the specific corrosive environments they are exposed to. Gates are typically in a submerged state, generally divided into immersed, tidal, and exposed areas. Depending on the gate's function, its location, and the media it contacts, the corrosion conditions can vary significantly. For example, gates in estuaries and shipyards are often exposed to marine climates with high salt spray concentration, high humidity, and large temperature variations. Gates in inland dams and bridges may also face corrosion from industrial atmospheres, harsh weather, and production or domestic wastewater.

The coating design for gates must balance anti-corrosion performance and aesthetic appeal.

The coating system is primarily designed based on environmental classification.

Ⅰ，Environmental Types

Environment Category	Environmental Type
Seawater	Gates immersed in seawater, exposed to seawater splash, and strong sunlight, corroded by seawater and pollutants in river estuaries.
Freshwater	Gates immersed in freshwater (e.g., rivers), typically in clean water with a pH of 6.5–7.5.
Coastal	Areas on the sea surface and within 1 km of the coastline, severely affected by sea salt particles.
Industrial urban	Areas with dense industrial activity or cities, severely affected by sulfur dioxide.
Others	Rural and mountainous areas outside coastal zones and industrial cities.
