I'm looking to gather pricing information on a versatile roofing sheet machine that combines multiple functionalities. Could you provide detailed pricing options, including any variations or additional features that may be available? Additionally, it would be great to know about lead times for production and shipping, as well as any warranty or support services you offer. Understanding these factors will help me make an informed decision. Thanks!
