Descripción
Los ángulos estructurales son productos de acero laminados al caliente cuya medida transversal forma dos alas en ángulo recto (90°).
Vienen en presentaciones de 6.0mts. Para otras longitudes, previa consulta.
Aplicaciones
Se utilizan para la fabricación de almacenes, carrocerías, grúas, marcos, puertas, rejacería, señaléticas, soportes, techados, torres de transmisión, ventanas, entre otros.
