Our company performs construction work on the installation of bridges, overpasses, traffic tunnels, skotoprohoniv, pedestrian crossings and culverts using prefabricated corrugated metal structures. Such metal construction – an alternative to concrete structures in the construction of artificial structures in the road, rail and industrial sectors. The strength of the design is provided by the interaction of the metal structure with well-compacted soil around it. At the same load metal structures are less susceptible to plastic deformation entirely impossible for reinforced concrete pipes. CIM consist of separate elements – corrugated sheets, bent to a given radius and united together in the longitudinal and transverse directions using heavy-duty bolts.
