Galvanised coils, thin steel sheets that are dipped into a molten zinc bath so that a layer of zinc adheres to their surface. It is mainly produced by the continuous galvanising process, whereby rolls of steel sheet are continuously dipped into a bath of molten zinc to make a galvanised steel sheet; alloyed galvanised steel sheet. This steel is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to around 500°C to produce an alloyed coating of zinc and iron. This galvanised coil has good paint adhesion and weldability.
