Atmospheric corrosion of steels is a form of corrosion that occurs from moisture and oxygen associated with atmospheric conditions; contaminants such as chlorides and sulphur compounds – from the sea and pollution – increase the corrosion rates. Atmospheric conditions classify environmentally as industrial, marine, coastal, or rural, often in combination with their climatic zone (e.g. tropical, temperate, etc).
The best and most (cost) effective management of atmospheric corrosion is through fabric maintenance, particularly in marine and coastal environments.
