FerroFinestra W20
FerroFinestra W20 takes its origin from the British “Universal Range”. It is a complete line of hot-rolled steel profiles that gives a modern twist to the historic design of the 20th Century. Used both for external openings and internal partitions, it maintains stylistic continuity between the choices of the building envelope and those of the interior design. The wide range of possible finishes, from the industrial effect of “natural” steel to coating, guarantees great design creativity.
FerroFinestra W40
