The coil coating process is an engineering marvel. Coatings and film laminates are applied to coils of metal in a continuous and highly automated process prior to fabrication into final products. As a coil of metal – up to 72 inches wide and traveling as fast as 700 feet per minute – unwinds, both the top and bottom sides are cleaned, chemically treated, primed, oven-cured, top-coated, oven-cured again and recoiled for packaging and shipment.
Coil coating is recognized for its cost effectiveness, aesthetics, field performance and sustainability. The process is a closed loop system with greater than 98% VOC capture and conversion to fuel.
The European market sometimes refers to the finished product as "prepainted" or "precoated" metals or coils.
