Pre-Painted metal, often referred to as coil coated metal, is metal that has had a continuously applied film or coating. This process is commonly applied to coiled metals, typically aluminum or rolled steel, and is a highly automated process that can be customized depending on individual specifications or final product requirements.
The coatings are applied on a continuous basis via highly efficient production lines which can involve cleaning, single or multiple coatings on one or both sides of the metal, curing and laminating. The final product is then ready to be processed further and can be cut, bent, and generally worked without damaging the final coating.
The coated surface is highly customizable and can be a paint, powder or plastic, with an almost infinite range of colors and final textures available.
The coating process can vary according to the coating being applied, but there are typically 3 stages to the coating process.
The metal is usually cleaned to strip away any surface impurities or imperfections to ensure the coating can be applied uniformly. The cleaned metal is then usually chemically pre-treated with an agent to ensure the coating material will adhere to the metal.
The pre-treated metal is then sprayed with the desired coating, which may include various spraying and curing stages. It is not uncommon to have multiple layers made of different coatings for highly specialized products.
Once coated, the metal will go through a final finishing stage which may include a final cure before being coiled back up for further processing. During this stage the final product goes through a quality assurance check to make sure it meets the required specifications.
As pre-painted metals have almost unlimited options in terms of final coat material, color and texture, there is a high demand for the product in the market. The following are some examples where pre-painted metals have become widespread.
