A method of manufacturing microalloyed structural steels by rolling in a CSP plant or compact strip production plant, wherein the cast slab strand is supplied divided into rolling lengths through an equalizing furnace to a multiple-stand CSP rolling train and is continuously rolled in the rolling train into hot-rolled wide strip, wherein the strip is cooled in a cooling section and is reeled into coils, and wherein, for achieving optimum mechanical properties, a controlled structure development by thermomechanical rolling is carried out as the thin slab travels through the CSP plant. For manufacturing high-strength microalloyed structural steels with a yield point of >= 480 MPa, the available strengthening mechanisms are utilized in a complex manner in order to achieve an optimum property complex with respect to strength and toughness of the structural steels, by carrying out, in addition to the thermomechanical rolling with the method steps according to U.S. Patent Application Serial No. 09/095,338, a further influence on the structure of the thin slabs by changing the material composition in order to achieve a specific mixed crystal strengthening by an increased silicon content and/or a complex mixed crystal strengthening by an increased content of copper, chromium, nickel.
