How many years can hot dip galvanized flat steel be used?
Coastal areas usually refer to a region within a mile of the sea. The ocean atmosphere can spread deeper inland, especially on islands. The prevailing winds come from the ocean, and the climate is bad. If the wind is mixed with ocean fog, especially due to evaporation and accumulation of salt deposits, coupled with less rain and less frequent rain erosion, coastal conditions will be even more unfavourable. If there is any industrial pollution, there is more corrosive. Hot galvanized flat steel in such circumstances, usually 20 years or so.
Industrial areas are heavy industries, causing air pollution in the region. Pollution may be caused by fuel gas, such as sulfur and nitrogen oxides, or other gases released by chemical plants or processing plants. Particles suspended in the air, such as dust produced in the process of steel production or deposition of iron oxides, also increase corrosion. In such an environment, life expectancy is about 20-30 years.
Experience has shown that the extent of atmospheric corrosion varies from region to region. The service life of hot-dip galvanized flat steel is different in different environments.
