A method for manufacturing reinforced steel structural components is described. The method comprises providing a previously formed steel structural component, selecting one or more reinforcement zones of the previously formed structural component, and locally depositing a material on the reinforcement zone to create a local reinforcement on a first side of the structural component. Locally depositing a material on the reinforcement zone comprises supplying a metal filler material to the reinforcement zone, and substantially simultaneously applying laser heat to melt the metal filler material and create the reinforcement by drawing specific geometric shapes on the first side of the structural component with the metal filler material and the laser heating. And the method further comprises providing cooling to areas on an opposite side of the structural component. The disclosure further relates to a tool for manufacturing reinforced steel structural components and to the components obtained using such methods.
