We define operating machines the machines used in the road and in the building construction for moving the ground, asphalting and distributing cement and materials. 

They live outside, unprotected and in industrial environments. 

Two/three coats protection cycles are necessary to obtain high protections. Typical pretreatments are the sand blasting SA2 1/2, the epoxy zinc based paint and the epoxy/PU/acrylic cycle. 

The main aspect of the paint system is the excellent corrosion protection and the aesthetic beauty, which should not be excluded.
