The ribbed trusses used as feedstock in the ribbed SI60 all wiring structure.

They consist of upper longitudinal thread (ØS)  and two lower longitudinal wires (ØL), separated by a distance (H) defined by two stirrup-shaped waveform (ØD).

Are used in lattice structures and slabs minipainéis also lattice, and spacers armor. Its use reduces the cost of labor and the use of forms and shoring, promotes greater organization at the jobsite and speed in execution of projects
