The invention relates to method for coating sheet metals such as coils with a chromate-free, water-dilutable, organic UV-curing anti-corrosive coating, and for curing said coating by irradiation with UV light. The inventive method is further characterized in that a dispersion or emulsion is used as the UV-curing coating agent for forming the anti-corrosive coating that substantially consist of 25 to 80 wt.-% binder, 1 to 8 wt.-% photoinitiations, 0 to 5 wt.-% additives, 20 to 70 wt.-% water, and optionally a pigment. The coating agent is applied on the sheet metal, preferably in an inline method, dried to form a film and cured by UV light.
