The pre-assembled system
A new laying technique for wooden floors and roofs.
Our commitment to research and development
One of the main missions of our company is the constant commitment to improving the quality of work for our customers and for the organization itself. At Grosso we strongly believe in this concept, so much so that we strive day after day to provide better products and exceptional service.
This is why over the years we have evolved from a simple sawmill to the current stage of expert builders of wooden structures.
But how did all this evolution happen?
From cutting on site to factory pre-assembly
We started by introducing the concept of factory pre-cutting. Thanks to this process combined with the assembly drawing of our technical office, we have considerably reduced installation times and waste. In addition, we have increased the precision and cleanliness of the construction site compared to the previous technique of cutting and assemblying directly on site. This technique was first implemented through the use of power tools. We then developed a method that involves pre-cutting with a numerically controlled machine.


Thanks to our constantly evolving know-how during these past few recent years we have been able to see how this technique could be further developed.
For over 20 years, the company has been a manufacturer of wooden buildings (in x-lam and frame), where in addition to sustainability, the next most important key word is prefabrication.
And why not transfer this know-how to the construction of other wooden structures as well?
This is how we came up with the idea of implementing a prefabrication system for wooden roofs and floors.
The system
All the elements of the structure are expertly pre-cut in the company and subsequently pre-assembled in different modules which are than transported to the construction site and placed directly on the structure.
The pre-assembled module consists of the union of the main and secondary warping, with the covering matchboard above it. But that’s not all, the cover package (whether hot or cold) including insulation and membrane is also mounted together.
