Frex drain

Water pipe for pavement of elevated roads and bridge surfaces

[Dedicated drain to smoothly drain rainwater penetrated on the elevated road and bridge surface]

Materials are excellent in strength and corrosion resistance due to the use of spring steel (SUS304 or galvanized steel wire).
Because the shape is a spiral, it can be freely bent and is easy to use for construction.
It can correspond to any stretch due to a change in temperature when paving.
