The use of roll forming lines brings with it certain considerations that must be kept in mind. One of the most important things to remember is lubrication, which is essential for creating a barrier between the rolls and the surface that is being worked on. Without this barrier, tools would experience exponentially higher wear and need to be replaced more often. They also keep the process moving smoothly.
Safety is another major concern to keep in mind. The moving portions of the metal fabrication equipment can pose a hazard if not dealt with in a responsible manner; some workpeices move at speeds upwards of 800 fpm. Sharp edges on sheared metal and the high pressure of the rolls also need to be kept in mind.
The rolling process can result in microcracks, thinning or hardening of the material. However, the physical and chemical properties in general remain virtually unchanged.
