There are few materials for architecture that can combine lightness and strength, customization and high performance, aesthetic refinement and circularity of production. Among them is aluminum, a metal that, for more than 60 years, has been the raw material for the creations of Metra Building, a manufacturer of integrated building systems including casement windows and French windows, sliding doors, entrance doors, shutters, curtain walls, balconies, interior doors and partitions.

The company expresses its best through the work carried out by the Architectural Solutions division, a department in which Metra engineers doggedly dialogue with the best international architects and designers to design and build spectacular and technically advanced constructions. It is enough to cite some of the achievements followed by Metra Building to certify the level of excellence of the projects: the Louvre Pyramid in Paris, the renovation of the Battersea Power Station in London, the Bosco Verticale and the Lombardi Region Palace in Milan... For each project, customized solutions were found at the highest technological level.

Metra Building's Systems division, on the other hand, deals with standard products, with an extensive catalog of locking systems certified by the most relevant and recognized bodies. The production process of each window and door frame is fully controlled and guarantees the highest quality standards. It starts with the extrusion of the raw material, also including the realization of every detail or accessory, treatment or finish. Constant research is what represents every realization of Metra Building. The company also looks to increasingly green production through the use of Metra RE.AL.E low-carbon alloys, five types of billets that contain percentages of aluminum from recycling with peaks of 100 percent.
