What are the materials that corrode steel structures?

The steel structure has good corrosion resistance, good anti-seismic ability and very long time to use. It is one of the reasons why so many factories, commercial building and villas choose steel structure as the building material. But there are a lot of materials that corrode the steel structure, and Foshan steel structure tells us what we all have.
1. atmospheric corrosion: water and oxygen in the air will produce chemical or electrochemical action, which will produce rust layer.
2. there will be localized corrosion in the cracks of steel structures due to the retention of liquids.
3. stress corrosion is a steel structure that is not subjected to stress in a certain medium, usually accompanied by housing collapse.
Foshan steel structure, even if the installation of steel structure is good, but also need to pay attention to corrosion, corrosion hazards, corrosion is very important.
