A method of fabricating a precoated steel plate, the method including coating a steel plate by dipping the steel plate in a molten bath to obtain a precoat upon the steel plate, wherein the precoat includes an intermetallic alloy layer and a metal alloy layer. The intermetallic alloy layer is topped by the metal alloy layer. On at least one face of the plate, the metal alloy layer is removed in an area at a periphery of the plate using a laser beam, while leaving at least part of the intermetallic alloy layer in the area. The at least part of the intermetallic layer in the area has a thickness between 3 and 10 micrometers thick.
