New joist for the construction integrated by a metallic core formed by two rounds or similar profiles, arranged longitudinally at the base of the joist and a third profile of metallic nature arranged on the upper part of the joist, said metallic elements being burned by a wire which constitutes the abutment that surrounds the upper round descending all over the body of the beam with a certain inclination to close and burn both lower rounds, ascending to re-tighten the upper nerve meeting and thus form a metal core that is then permanently included in the sine of the beam forming with the body of this a homogeneous set of excellent metallic conditions.
