Construction materials, water supply and drainage, assembled manhole.

Leave the sale of manhole covers and replacement work through machine construction to us.

For the installation work of manhole covers, we recommend the Parabola method using a parabolic cutter. The Parabola method is a new technique that cuts the asphalt surface into a circular spherical shape for the replacement and repair of manhole iron covers. It finishes the work neatly and accurately. The parabolic cross-section has excellent adhesion and there is no wobbling after construction.
