Coil coating provides an extremely efficient method of producing a high-quality, uniform coated finish over metal substrates with an automated, continuous process.  More than 800 million tons of coil-coated metal materials are produced and shipped in North America annually.  With coil coating, metal substrates are painted prior to, instead of following, fabrication, thus is sometimes referred to as pre-painted metal.

During the coil coating process, metal coil is unwound, cleaned, pre-treated and coatings are applied to a flat, continuous strip of metal.  It is then cured with heat, cooled and rewound back into coils that are to ship to the fabricators.  There the metal coils are unwound allowing the sheet to be cut and post formed, at the fabricator, to the desired shape and size for further processing or assembly. 

Coil Coating

Provides Improved Quality and Efficiency

Coil coating is significantly more efficient than other application methods with line speeds at some coil coating lines operating as high as 700 feet per minute, with rapid curing possible, well under 60 seconds.

Coil coating provides many benefits over spray applied coatings as a coil applied film provides for a more uniform thickness, across the sheet and little to no paint transfer waste.

Coatings for Coil-Applied Applications 

Various types of coatings and industrial adhesives are coil applied with different curing methods such as induction, thermal, UV cure and infrared with the majority of curing using conventional convection ovens.  Manufacturers of coil applied coatings give special consideration to many factors when formulating coatings such as the resin technology, solvent system, catalyst, crosslinking, lubricants or surface modifiers to accommodate proper cure, leveling and minimizing surface defects.

Coil applied coatings provide exceptional physical, chemical resistant properties and can be formulated to deliver exceptional durability against exterior environmental conditions of humidity, corrosive environments, UV radiation, etc.  Working with a chemical and coatings manufacturer with experience in custom coil applied coatings provides the most benefit to coil coaters.

Benefits of coil coating

Why designers like prepainted metal

Prepainted metal products provide many advantages in both design flexibility and in the realisation of that design through the fabrication and manufacturing process. The products also have numerous environmental advantages over alternative materials and coating processes.

Advantages in design

Prepainted metal provides a very high-quality painted surface in a wide array of colours and textures.  It is also available with printed films to give effects such as woodgrain.  The surface of a prepainted metal can be either very matt or high gloss, smooth, orange-peel or embossed.  Prepainted metals are available in all the usual steel and aluminium grades and alloys so you can balance formability, strength and appearance in the final product.

Prepainted metal is the choice for sustainable design.  Detailed independent life cycle assessment (LCA) has shown that the environmental impact of prepainted metal is less than that of post-paint metal across a wide range of impact categories. Prepainted metals are also easily recyclable.

Although the organic coatings used in coil coating are generally thinner than post-applied powders and  films, they still give better in-service performance.  So, you use less paint which minimises resource consumption and enables you to cut down or even eliminate maintenance and re-painting. 

The continuous coil coating process gives the highest standards of quality assurance through coil to coil consistency and has a significantly lower environmental emissions than batch or post-painting processes.  The coil coating processes are operated in accordance with the latest national and European standards for VOC emissions and emissions to water; this environmental compliance means that prepainted metals are the materials of choice in a wide range of applications.

Advantages in production

Using prepainted metal enables domestic appliance and other manufacturers  to save money by making their manufacturing operations run smoother and more consistently.  Productivity and yield are improved, while manufacturing, energy, inventory and financial costs are reduced.

By utilising prepainted metal in their process, manufacturers are able to eliminate their paint lines which are usually the major bottleneck in their operation. Capacity constraints are minimised, potentially improving ROCE.

The cost of complying with environmental regulations is significantly reduced, or even eliminated.  The cost of the disposal of hazardous waste associated with the painting operation is also eliminated.

Scheduling problems and the costs associated with batch-type processing are minimised or removed altogether.  Since input material is more directly related to output, the processing time is reduced and stocks are minimised.

The consistent quality of coil coated materials reduces the need for re-work and lowers non-conformance levels and associated costs.  Above all, using prepainted metal allows the manufacturer to concentrate on their core competencies and leave the production of high-quality paint finishes to the experts.
