Color-coated board is a panel or sheet material used for painting and graffiti, commonly made of wood, plastic, or metal. It features a smooth surface that can be drawn on with colored chalk, oil paints, watercolors, or markers to create patterns and images. Typically used in children's art, education, and entertainment activities, it is also employed by artists for creative work and copying practice. It is easy to wipe clean and reusable, allowing for multiple creations and modifications. Color-coated board is widely used in schools, kindergartens, art studios, and homes.
The difference between color steel plates and asbestos shingles
Color-steel sheets and asbestos shingles are widely used construction materials. Many people often hesitate when buying: should they choose color-steel sheets or asbestos shingles? Below, we will introduce the differences between the two.
Features vary. Color steel is a galvanized steel plate coated with an organic layer, featuring vibrant colors, high strength, and low cost. Asbestos shingles are a type of roofing material for waterproofing, with excellent fireproofing, moisture-proof, corrosion-resistant, heat-resistant, and lightweight properties.
Different application fields. Color steel plates are suitable for constructing large-span buildings and are widely used in industrial factories. Asbestos shingles, on the other hand, are mainly used in residential buildings.
Durability varies. The lifespan of color steel plates is relatively longer than that of asbestos shingles.
Color steel plates have factors that are hard to surpass in various indicators, hence their market share continues to rise. Meanwhile, the market share of asbestos shingles has somewhat decreased. However, from a long-term perspective, both products still have a broad space for development.
Color Coated Steel Sheet
Color coated steel sheet is produced on a continuous mill using cold-rolled steel strip and galvanized steel strip (electro-galvanized and hot-dip galvanized) as the base material. After surface pretreatment (degreasing and chemical treatment), a single or multiple layers of liquid paint are applied by roller coating. The sheets are then baked and cooled to obtain the finished product.
Introduction
Cold-rolled steel strip and galvanized steel strip (electro-galvanized and hot-dip galvanized) serve as the base material on continuous mills, which are then subjected to surface pretreatment (degreasing and chemical treatment). A layer or multiple layers of liquid paint are applied by roller coating. The sheets obtained after baking and cooling are called coated steel sheets. As the coating can come in various colors, coated steel sheets are commonly referred to as color coated steel sheets. Moreover, since the coating is applied before the steel sheet is formed, it is called pre-coated steel sheet internationally.
Color coated steel sheets involve applying an organic coating to the surface of steel, offering aesthetic appeal, vibrant colors, high strength, excellent corrosion resistance, and ease of processing and shaping. Moreover, they enable cost reduction and pollution reduction for users.
Since the establishment of the first continuous coated steel sheet line in the U.S. in 1935, colored coated steel sheets have been widely utilized. Today, there are over 600 types of colored coated steel sheets available. These sheets combine the benefits of both organic polymers and steel plates, offering excellent coloring, molding, corrosion resistance, decorative properties, and the high strength and ease of processing of steel plates. This allows for easy stamping, cutting, bending, and deep drawing. Consequently, products made from organically coated steel sheets possess superior practicality, aesthetics, workability, and durability.
Baosteel Color Coated Steel Coil is a product made from substrates such as hot-dipped galvanized steel, hot-dipped aluminum-zinc steel, and electro-galvanized steel. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or more layers of organic coatings are applied to the surface, which are then baked and cured to form the final product. The name "color coated steel coil" comes from the various colors of organic coatings applied to the steel coils, abbreviated as "color coated coil."
The colored coated steel strip, based on hot-dipped galvanized steel strip, not only has a zinc layer for protection, but also the organic coating on the zinc layer serves as a covering and protective layer, preventing rust on the steel strip. It has a longer service life than galvanized strip, about 1.5 times longer.
Key Points for Construction of Color Steel Maintenance Projects
In steel structure projects, color steel panel maintenance is a subsequent process, with the quality of maintenance directly affecting the overall project's appearance and also involving the project's waterproofing performance and usability. Therefore, during the construction of maintenance work, the following construction points should be mastered, operations should be carried out meticulously, and proper construction materials and methods should be used to ensure that both the appearance quality and waterproofing effect meet excellent standards.
ÿ
Application:
Color coated coils are lightweight, aesthetically pleasing, and have excellent corrosion resistance, making them directly processable. Colors typically include gray white, sea blue, and brick red, and they are mainly used in the advertising, construction, household appliance, electrical, furniture, and transportation industries.
The paint used for color coated coils is selected based on the application environment, such as polyester silicon-modified polyester, polyvinyl chloride plasticizer, polyvinylidene chloride, etc. Users can choose according to the application.
