In any case, the steel coils should never be stored or stored in a damp environment.Because the action of the capillary will suck moisture into the surface of steel coil, moisture gas or water will not evaporate normally, which may lead to deterioration of product characteristics, shorten the expected service life, and affect the appearance of the product. The storage for related products,such as color corrugated steel sheets,sandwich panels,etc.,also requires special attention to this problem.
