TR4/TR5 roofing sheet roll forming machine or we call it as trapezoid profile roll forming making machine is designed to make the metal roofing sheet machine by rolling forming working principle. Tr4 or Tr5 is the quite popular design in South American, especially in Peru. Here I will take the following drawing profile for your reference:
For this profile, the most difficult part is that during the rolling forming, there maybe waves on the profile or there are some scratch on the surface of the coil. The reason as that the wave height is too high, it needs around 22 roller stations to do the rolling forming. Here is the machine design pictures for your reference:
