How to ensure the corrosion resistance of steel decks

The steel deck plays an important role in the structure, so it must be ensured that the steel deck is not corroded. How to do it?

1. The steel deck should at least use galvanized steel plate. Generally, the amount of double-sided galvanizing is 120g/m²--275g/m², and the high galvanized can be as large as 350g/m². This measure is to sacrifice zinc to protect it when it is corroded. steel;

2. Some are used for roof panels or wall panels, in addition to the galvanized coating of steel plates, chemical coatings with more protective functions, such as PE, PVDF, etc., are added. Because the roof panels or wall panels are not indoors, and Is exposed to outdoor air, the possibility of corrosion is greatly increased.

3. Before installation, the steel deck should not be touched to damage the coating, which may be corroded by air or moisture.

4. During storage and transportation, be sure to do a good job of packaging and maintenance to prevent corrosion from the cut edge of the steel deck. During shipping, since seawater is very corrosive, multi-layer protection can ensure that it will not be corroded during transportation.
