The steel plate is coated with organic coatings. The coating can have various colors. Color-coated steel plates are named from this, referred to as color plates, also known as organic-coated steel plates. Color-coated steel plates are painted before the steel plate is processed and formed. Coating is also called pre-coated steel plate or painted plate abroad. The organic coating of the color-coated plate plays a covering and isolation role, preventing the steel plate from rusting and extending its service life.
The substrates of color-coated boards include cold-rolled substrates, hot-dip galvanized substrates, electro-galvanized substrates, hot-dip aluminum-zinc substrates, aluminum plates, aluminum-plated plates and stainless steel plates, etc.
The types of topcoat coatings for color-coated boards can be divided into: polyester, silicon-modified polyester, polyvinylidene fluoride, high-durability polyester, etc.
The production process has evolved from one coating and one drying to two coatings and two dryings, and the three-coating and three-baking process has also appeared.
