Product Description G40 Galvanized Sheet
The coating designation G40 represents the type of coating and the weight of the applied coating. The letter “G” indicates that the coating is galvanized, meaning zinc-based. Meanwhile, the number “40” represents the thickness of zinc on the surface of the steel sheet. Galvanized steel sheets are covered with a zinc coating to provide corrosion resistance. The G40 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G40 is the average coat weight and therefore provides moderate protection.
