Metal sheet cut on-premise vs. pre-cut sheets

Thank you. Certainly there can be a lot of freight cost embedded in shipping finished panels. There's also always a chance for error and getting panels that are not the correct length. That said, in-plant machines are often larger machines which can produce heavier panels with less chance for oil canning. Machines that are trailered to job sites also can go out of adjustment and run inferior panels. However, certainly, lots of very good, quality panels are made on job sites. I would look a lot at the quality of the metal and the coating on the metal. Also, be sure that you understand what warranties you're getting and who is standing behind the warranties.
