Color-coated sheet is made of cold-rolled steel sheet and galvanized steel sheet as the substrate. After surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating is applied in a continuous method (roller coating method), and baked and cooled The product.
The color-coated steel plate refers to the color-coated steel plate, and the color-coated steel plate is a steel plate with an organic coating. Color steel plate is divided into veneer, color steel composite plate, floor bearing plate and so on. So what is the difference between the two, the color steel plate manufacturers will tell you what are the specific differences between them.
The specific differences are as follows:
1. During the refining process, the substrate of the color-coated board is a steel strip used for coating. The front and back of the color-coated board are very important. Usually, the two surfaces of the color-coated board have color, coating properties, and High quality requirements. Color-coated board has strong hardness and flexibility. Its coating is resistant to mechanical effects such as scratches, friction, collision, and press-in. The coating of the color-coated board and the substrate are deformed together without damage. .
From the end of production, color-coated boards have an interval between the performance of the original coating and the time it must be overhauled to maintain its protective effect on the substrate. Under the influence of use and over time, it will gradually deteriorate, and a major repair must be performed to make it more durable.
2. The color steel plate is based on cold-rolled steel plate, and after degreasing and phosphating, it is hot-dip galvanized on both sides under the protection of nitrogen, and a chemical conversion film that is easy to adhere firmly to the primer is applied. He was painted with an epoxy primer, and finally a chemical-resistant color finish.
The color plate is a color steel plate, which is coated with a layer of polymer material on the steel plate, which is divided into one side and two sides. Most of the single side has a pattern on the surface.
The above two major points are the differences between the color coated plate and the color steel plate. Although the two names are similar, the production method and the scope of application are different, so we must choose our own according to our actual situation when choosing to use it. We need to learn to distinguish between the required product and the type of building used in different boards. Only boards that meet the requirements for use can play a good effect.
