Discover who we are

With aluminium in the DNA

We have been processing aluminium for over 60 years to produce integrated systems for the building industry.

Our product ecosystem consists of windows, casement doors, entrance doors, curtain walls, balconies, shutters, interior doors and partition walls.

Each production process is carried out and supervised in-house to guarantee the highest level of efficiency and quality. The result of an in-depth knowledge of both the raw material and the production chain, of constant updating and technological investment, has allowed us to organise METRA Building into two divisions:

  • Systems, which includes the products and integrated systems in our catalogues;
  • Architectural Solutions, which brings together large custom projects for the world of architecture.
