Hot-rolled high-strength steel elongated structural members and method of making same are disclosed by hot-rolling high-strength steel having a specific chemical composition to provide structural units. The units are then welded together to provide structural members of desired geometrical configuration including a thin web with opposed thicker flanges extending therefrom to increase the load bearing capacity of the members.
