1. Introduction:

Developed and designed in-house and tested in practice, we have produced a series of cutting machines and cutting lines that will be regarded as industry leading since 2003. All of our CNC cutting machines can be equipped with oxy-fuel and/or plasma cutting equipment.

CNC-CG series is our standard cutting machine which not only can cut different profiles/shapes but also can cut strip/straight plate.

Guoheng earned its global market position by offering extremely innovative cutting solutions for customers in steel construction, offshore, shipbuilding, process and crane building industry.

We also provide user-friendly broad choices and options that allow you to configure your CNC cutting system with the capacities, speed and accuracy of your needs.
