"G400" is a designation for a specific type of galvanized steel coil. Let's break down the meaning of the "G400" designation:
G: The "G" stands for galvanized, indicating that the steel coil has been coated with a layer of zinc to protect it from corrosion. Galvanizing involves applying a thin layer of zinc to the surface of the steel through a process known as hot-dip galvanizing. This coating forms a protective barrier that helps prevent the underlying steel from rusting.
400: The number "400" refers to the minimum coating mass (weight) of zinc per unit area on both sides of the steel coil. In this case, "G400" indicates that there is a minimum of 400 grams of zinc per square meter on each side of the coil. The coating mass is a measure of the amount of zinc applied to the steel and is used to assess the level of corrosion protection provided by the galvanized coating.
In summary, a G400 galvanized steel coil has been coated with a specific amount of zinc to provide corrosion resistance. This type of galvanized steel is often used in applications where moderate corrosion protection is required, including various construction and manufacturing uses.
