As an alternative to painting finished articles, the coil coating process provides many benefits because of the efficiency of applying paint by the roller-coating process to flat strip.
- Pre-painted metal is produced from flat metal strip that is cleaned, treated and coated in a continuous process. This yields better and more efficient cleaning, pre-treatment, painting and curing operations, and hence, a product of higher, and more uniform quality than is usually obtained when post-painting formed parts.
- Close control over the coating operation that the coil coating process allows results in a high quality, reproducible and reliable finish. A prepainted part, even with a reduced paint film thickness, will generally last longer than an equivalent part with a post-applied coating.
- Prepainted steel and aluminium products for external exposure in some of the harshest climates are guaranteed for anything up to 40 years, so re-painting and eventual replacement is minimised. Coil coating reduces or in many cases eliminates the need for ongoing maintenance and makes products last longer.
Whatever the application, coil coated steel or aluminium present an efficient design solution. The inherent properties of the metals give them a high strength-to weight ratio and continued development of steel grades and aluminium alloys can be enjoyed in pre-painted form through the coil coating process.
