A coil painting Line is a coil processing line which coats steel or aluminum strip with one or more coats of protective paint. The paint can be sprayed or rolled onto the surface of the strip. The finished product must be primed, painted and cured in a single pass. Most coil paint lines are a continuous process with sophisticated control to maintain paint thickness, curing and recoiling with protective wrap.
