How long does steel decking last

How long does steel decking last?

Many people ask this question, and the answer to this question is obvious.

Related to steel decking itself

The service life of the steel decking is related to the product itself. Steel decking are generally made of galvanized materials, and the amount of galvanizing determines the life of the steel deck. There are several types of galvanized steel decking according to customer requirements: 120g/m², 150g/m², 180g/m_², 275g/m², of course, the higher the galvanized amount, the stronger the corrosion resistance of the steel decking, then the life of steel decking is longer. According to the laboratory test results, when the double-sided galvanized steel decking is 275g/m², the service life exceeds 23 years.

Related to the geographical environment

The service life of the steel decking is related to the geographical environment where the product is applied. Under normal circumstances, the lifespan of a double-sided galvanized steel decking of 275g/m2 will exceed 50 years in a dry indoor environment; the lifespan of steel decking of the same material in a humid outdoor environment will be much shorter; moreover, the steel decking with a galvanizing amount of 275g/m² is in a seaside environment, and local corrosion may appear on the steel decking after a few years.

Related to the maintenance of steel decking

The service life of steel decking has a considerable relationship with the usual maintenance. For example, pay attention to protecting the zinc layer on the surface of steel decking during using, or add another ceiling under the steel deck, which will prolong the service life of the steel deck; in order to prolong the service life of steel decking, spray paint on the galvanized steel decking, or Direct selection of galvanized color-coated panels.

To sum up, the life of the steel decking is related to the above factors.
