Coil coating provides a consistently high quality product that is durable, corrosion resistant, cost effective, recyclable and more environmentally friendly than other alternatives. In this article, we will learn about the coil coating process, the different coating technologies used for coil coating.   Main steps The coil coating process starts with a coil of untreated sheet metal that is unrolled, treated, coated, cured, rewound and packaged for shipping at a rate of 100-200 meters per minute.

  Converting from in-house painted metal to outsourced pre-painted metal can save manufacturers money and time, and can ensure products of the highest quality. The most important issues to consider when converting to a pre-painted operation are time, capital expense, manufacturing costs and environmental compliance. The following are 10 indicators that manufacturers should consider using   coated steel or aluminum.   1. In-house paint shop costs are on the rise. When maintenance budgets are growing and capital investments are needed to comply with strict EPA regulations, pre-painted metal and aluminum are often cost effective alternatives to in-house paint lines.
