Why Zhongtuo metal roofing sheet machine is different with others?

  1. For the rollers, all we design with keynotes for rollers and shaft tightly together:

2.For the spacer, we also use seamless pipe and thickness is more thicker to make sure the machine long time to use and high accuracy. This kind of spacer will not go rusting easily. It can protect the shaft in some degree:


3.For the rollers, we use the material GCR15 quenching at 58 degree to make sure the hardness of rollers. For some bigger rollers, we will do the quencing even if two or three times.

4.The last but the most important of our roofing sheet machine is easy for installation. We will put the PLC and hydraulic station all together, when machine arrives to you, simply connect the main electricity, that is enough. All the installation could be finished within half an hour.


For the PLC control, Zhongtuo machinery designs like this:
