The HelCor® pipes are designed for all road and railway live load classes as well as under the load of special vehicles. The 100 durability can be achieved by properly design corrosion protection coatings based on environmental conditions. The HelCor® pipes could be design just as continuously hot-dip galvanized and as an option with an additional 300 μm polymer film (TrenchcoatTM or W-ProtectTM) on one or both sides, in an environment with increased corrosive aggressiveness.

Roads and railway culverts
Underground passages
Hydrotechnical structures
