Introduction
Coated panels are also called organic coated panels or pre-coated steel panels. They are based on metal coils (cold-rolled panels, hot-dip galvanized panels, aluminized panels, high-aluminum alloy panels, stainless steel panels, etc.) and are coated on the surface. Or laminated with various organic coatings or plastic films. Because it is a coil that has been surface-coated in a metallurgical factory and can be directly processed into products by users, it is also called pre-coated coil.

The coated plate has the advantages of both organic polymers and steel plates. It has the good colorability, formability, corrosion resistance and decorative properties of the organic polymer, as well as the high strength and easy processability of the steel plate. It can be easily Carry out processing such as punching, bending, deep drawing, and welding. This makes products made of organically coated steel plates have excellent practicality, decoration, processability and durability.
There are many varieties of coated sheets, about more than 600 types, but there is still no unified classification method, because it is difficult to find a standard for distinguishing among the many varieties. At the same time, each manufacturer has its own unique equipment and processes, and there are many types of products. Now it is only classified according to general habits.
1. Classification according to the substrate used. Substrates commonly used for organically coated steel sheets include: cold-rolled sheets, hot-dip galvanized sheets, electro-galvanized sheets, alloy sheets, galvanized aluminum sheets, electro-galvanized zinc alloy sheets, tin-plated sheets, chromium-plated sheets, aluminum sheets, etc.
2. Classified by processing technology. According to different coating methods, there are organic coated steel plates made by roller coating, spray coating, powder method, lamination method, printing method, etc. Depending on the number of coatings, there are organic coated steel plates made by different processes such as one coating and one drying, two coatings and two dryings, three coatings and three dryings, four coatings and four dryings. According to embossing or printing processing, it can be subdivided into wood grain plate, marble grain, leather grain, cement mortar grain and other coated steel plates.
3. Classify by coating type. Usually classified according to the coating used to make organic coatings, there are polyvinyl chloride coated steel plates, polycool coated steel plates, acrylic coated steel plates, fluorocarbon coated steel plates, silicon polycool coated steel plates, etc.
4. Classification according to coating performance. According to the performance characteristics of organic coatings, there are high weather-resistant coating boards, high-temperature resistant coating boards, self-extinguishing coating boards, sterilization coating boards, non-stick snow coating boards, fingerprint-resistant coating boards and self-lubricating coatings. Board etc.
5. Classified by special coatings and uses. For example, there are epoxy zinc-rich coatings, organically coated steel plates with cold-rolled steel plates as substrates, surface flocked steel plates, and some special machine-coated laminated boards, such as wood-tied membrane boards, sandwich panels, anti-vibration boards, etc.
