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. Los elementos estructurales alargados de acero de gran fuerza enrollados por calor y el método para elaborar los mismos, se describen mediante el acero de gran fuerza de enrollado por calor que tiene una composición química específica para proporcionar unidades estructurales; las unidades son entonces soldadas juntas para proporcionar elementos estructurales de una configuración geométrica deseada que incluye una malla delgada con bridas más gruesas opuestas que se extienden desde la misma para incrementar la capacidad de soporte de carga de los elementos.
