It is 850 tile roll forming machine. Client ordered one automatic line including hydraulic decoiler with coil material car and roll forming machine. Client sent messgae to me. So i am waiting for helping my client to install and operate their first roof panel machine line. I prepared the Product instruction for client. But i think it is necessary for taking video to guide them to install hydraulic decoiler with coil car.  After sale service is beginning since today. Technology service is long life for all of our clients.  This is our service.
