Quieter Type Wire Saw or Diamond Wire Saw

Wire-sawing is a flexible sawing technique that can be applied under various situations with excellent cutting performance. It can be used to cut large area and remove heavily reinforced concrete, such as towers and bridge sections. It can also be used to cut concrete in a confined workspace or even inside an inhabited building without causing much disturbance. Quieter type wire sawing or diamond wire sawing operates very fast and only emits low level of noise.
