For the most complex projects we propose to our Clients to manufacture first a prototype of the product that can be analysed and checked in the details in order to define and reach all the characteristic elements of the product with the full satisfaction of the Client.

Especially the lattice steel towers of new generation are often pre-assembly tested in order to verify the conformity and avoid problems during the assembly on site.

Furthermore Colombo has consolidated partnerships with tower testing stations for the load tests in real scale where the design results are validated and confirmed by the mean of the application of loads simulating the exceptional conditions that could influence the structure during its life cycle.
