Some details in everyday life aren’t noticed immediately, but they are essential.

These are those that combine elements that otherwise could not exist and they do this with efficiency, design and innovation. Here is what it means for us to build the invisible and we build it for who can see quality.

The We Build The Invisible group is a brand made from Colcom and Sadev. Together, these two companies are the protagonists of innovation in the field of systems and accessories for tempered glass.

The solutions we offer range from interior design, such as hinges for shower enclosures or door locks, to exteriors, such as structural facades and balustrades.

What unites our companies is a tailor-made design and the search for new solutions and safety, always on top. The entire production process (design, processing and finishing) and distribution on the market (national and international) takes place within the group, always guaranteeing the best solution.

Colcom’s soul Is characterized by his vocation for the made in Italy design and spirit of innovation. The company was founded in 1961 and since then has never stopped producing original equipment. The patent of automatic hinges and then the birth of Biloba and Triloba – international patents of Colcom – are two of the fundamental stages of this company that continues to innovate itself within We Build The Invisible.


Sadev is specialized since more than 20 years in the design, development and manufacture of hardware for exterior glazing, structural facades and balustrades.
You become one of the most important companies in the sector only if you listen and understand the market, only if you propose quickly new solutions with excellent quality. That’s why Sadev is part of We Build The Invisible.
