The service life of GI steel coil with spangles in stock has a lot to do with the surrounding environment. It can be used in farmland areas above lOa. In urban or coastal areas, use only 5a. This is because urban air contains: corrosive gases and accelerated corrosion of the zinc layer. In order to increase the service life of wholesale galvanized steel roofing panels, in addition to the passivation treatment, the organic coating or organic layer treatment is usually carried out outside the galvanized coil. In this way, not only the service life is improved, but also the decorativeness of the surface is greatly improved.

Due to the good corrosion resistance of hot sale galvanized steel coil, the source of zinc is relatively easy and relatively inexpensive, so the production of GI steel coil with spangles in stock is superior to other coated coils. In recent years, galvanized coils have been used more widely and are increasingly used in the automotive industry. For example, in the United States in 1979, the hot sale galvanized steel coil used in the automotive industry was 2.6 million tons, and by 1985 it had increased to 3.3-3.7 million tons.
