A method for producing expanded metal profiles, consisting of subjecting a metal strip of width less than the development of the profile to be produced to the following operations: forming longitudinal slits in at least that longitudinal band which is to form the central web of the profile, bending the edges of the slits, profiling said strip, transversely stretching that band containing the slits, pressing areas of said central web in correspondence with said stretched band to displace them external to the plane of said web, characterised by previously forming holes in correspondence at least with the ends of the lines along which slits are to be formed.
