Box Culvert for Public Utilities Conduits

Neturen’s PC steel bars are high-strength steel bars that are used to apply compressive force in advance to pre-stressed concrete, a material vulnerable to tension, to improve its properties and enhance the strength of concrete buildings and serve to apply constant pressure to concrete at a yield point of 80%.

Neturen’s PC steel bars are widely used not only for applications such as concrete piles for foundation, concrete poles for power transmission and communication, concrete sleepers on railway tracks, sewers and box culverts for public utility conduits, but also for bridges and construction.
