Coil Coatings

Why Choose Coil Coatings?

Traditional liquid spray coatings are wonderful for coating metal substrates. They provide even coverage, easy application, low cost, low bake, and with modern application technologies provide low loss and high efficiency. However, your facility still has to maintain and operate a paint line in order to produce painted parts. In some circumstances this is unavoidable, but for components formed from sheet metal, coil coating offers an attractive, zero waste alternative. Our unique chemistry allows parts to be formed after they are painted, even in cases where forming involves considerable stretching of metal or sharp bend angles. Northern's coil coating products can be customized to meet your specific needs or those of your end customer.
