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.
