The invention relates to a method for making a sandwich element, comprising blankets of steel plate and therebetween a core member of an insulation material which is joined with the blankets for producing an integral sandwich element. In the method the blankets of steel plate are profiled as desired prior to joining the same with the core member. The method comprises supplying a production line with a roll of coiled steel plate, which is uncoiled and cut for blanket sections of a certain length which are carried to a profiling mechanism to be profiled as desired prior to mating the same with a core member. The method also comprises supplying the production line with one or more surface films different from each other in terms of colour and/or other properties, which are attached to the external surface of a blanket section for coating the same with a surface film of a desired colour prior to its passage to the profiling mechanism.
