Systems and methods are described for roll-forming metal substrates. The metal substrates are subjected to induction heating during the roll-forming process by exposure to time-varying magnetic fields, such as by exposure to a rotating permanent magnet, or exposure to laser radiation from a laser source. Heating of the metal substrates allows improved formability or plasticity of the substrate in order to reduce or eliminate damage to the substrate during roll-forming to low bending radius to thickness ratios. Heating of the high-strength metal substrates can also function to temper the substrates and/or improve surface corrosion resistance and form high-strength end products with desirable properties. Se describen sistemas y métodos para perfilar sustratos de metal. Los sustratos de metal se someten a calentamiento por inducción durante el proceso de perfilado por exposición a campos magnéticos que varían con el tiempo, como por exposición a un imán permanente giratorio o exposición a la radiación láser de una fuente de láser. El calentamiento de los sustratos de metal permite mejorar la formabilidad o plasticidad del sustrato para reducir o eliminar el daño al sustrato durante perfilado a relaciones bajas del radio de doblez al espesor. El calentamiento de alta resistencia de los sustratos de metal también puede ser función de templado de los sustratos y/o mejorar la resistencia a la corrosión superficial y formar productos finales de alta resistencia con propiedades deseables.
