Coil coating is one of the most advanced, efficient and environmentally friendly means of coating metals available. Using pre-coated metal offers manufacturers a simplified manufacturing process, cost savings and a more environmentally friendly plant. Manufacturers of coating lines invite you to read on for the benefits of this technology.
In the old days of traditional manufacturing, steel and other metals arrived at the factory in their raw, untreated and unpainted state. This was a costly, time-consuming and environmentally harmful practice. The coil coating process was pioneered in the 1930s to coat and pre-treat large metal coils before they arrived at manufacturing plants. Today, over 800 million tonnes of coil-coated steel and aluminium are produced and shipped annually in North America alone. Thousands of products in dozens of different industries can be manufactured more efficiently using colour coated metal.
Coil coating is one of the most advanced, efficient and environmentally friendly means of coating metals available. Large metal coils (including cold rolled steel, electro-galvanised, aluminium, stainless steel and copper) can be coated in a continuous, highly automated process prior to manufacture. In this continuous process, the metal is uncoated and then cleaned and chemically treated. Depending on the product specification, one or both sides can then be primed and/or topcoated, oven cured and rewound for shipment.
The range of coatings available is virtually unlimited and includes polyester, epoxy, vinyl, plastisol, water-based emulsions, dry lubricants and more. In addition, product quality is constantly improving due to new industry-specific coatings being regularly marketed and advanced testing being carried out throughout the coil coating process.
The coating line process is designed to produce highly homogeneous coatings of impeccable quality. These coatings are applied with precision using special equipment that provides a high quality finish. The coatings can be on both sides of the metal and conform to the finished specification.
To ensure the best possible results, extensive quality control tests are carried out during the coil coating process. For example, the viscosity, colour, gloss and physical properties of the metal substrate and coating are tested prior to application. When coating open coil metal, the surface treatment process is constantly tested and adjusted to ensure a high quality finish. In addition, paint thickness, coating properties and line speed are controlled and measured.
In order for the coil coating industry to prosper in the long term, LITONG will continue to offer advantages over competing industries in a number of areas, as follows.
Low consumption: the coil coating process embodies inherent efficiencies such as high coating transfer efficiency and custom width substrates.
Consistency of quality: coil coating is a highly automated continuous process that contributes to the production of consistently high quality products.
Recyclability: coated metal is fully recyclable and a viable infrastructure exists to recycle scrap metal.
Product durability: some building products have a life expectancy of up to 40 years before they need to be repainted.
Low emissions: low waste emissions, including water and volatile organic compounds.
Cost effectiveness: for most applications, the coil coating process represents the most cost effective way to paint metal surfaces.
