Galvanized steel coil, the thin steel plate is immersed in the melting zinc tank, so that the surface of the thin steel plate with a layer of zinc. The main use of continuous galvanizing process production, that is, the rolling steel plate is continuously immersed in the melting zinc plating tank made of galvanized steel plate; Leģēta cinkota tērauda loksne. This steel plate is also made by hot dipping, but immediately after being taken out of the tank, it is heated to about 500 ° C to form an alloy film of zinc and iron. Šai cinkotajai spolei ir laba pārklājuma necaurlaidība un metināmība.
