20m Three Legs GSM Mast Mobile Cell Tower

Before Plate blanking, it needs leveling, to ensure the accuracy of materials. We use CNC plasma cutting machine and CNC flame cutting machine to ensure that the plate blanking size of the accuracy of ±1.5mm.

We have various Bending Machine, and the use of the largest 4000 tons CNC press (Model: W67K-4000/12500) to complete the bending of steel pipe; Multi-standard, adjustable mold to meet the different diameter of the steel pipe manufacturing.

To ensure accuracy, we use CNC plate production line manufacturing the welding of steel pipe support. Firstly small drill makes positioning hole, and then drill hole to the required diameter to make sure the whole precision.
