High Performance Sheet for Steel Structure plants villa
The coated plate has the advantages of both organic polymers and steel plates, both organic polymers, good colouring, forming, corrosion resistance, decorative, but also the high strength of the steel plate and easy to process, it can be easily punched, bending, deep-drawn, welding and other processing. This makes the products made of organic coated steel plate have excellent practicality, decorative, processing, durability. Coated sheet of many varieties, about more than 600 kinds, but there is still no a unified classification method, because of the many varieties of difficult to find a distinction between the standard, at the same time, each manufacturer has its own unique equipment, technology, product variety. Now only according to the general customary classification.
Classified by substrate type, organic coated steel plates typically use cold rolled sheets, hot galvanized sheets, electro-galvanized sheets, alloyed plates, galvanized aluminum plates, galvanized zinc alloy plates, tin plates, chrome plates, aluminum plates, and others.
Classified by processing technology, the different coating methods include roller coating, spraying, powder coating, composite film, and printing. Depending on the number of coating and baking cycles, there are single coating and baking, double coating and baking, triple coating and baking, and quadruple coating and baking processes. These processes produce various types of organic coated steel. Additionally, based on embossing or printing, they can be further subdivided into wood grain, marble grain, leather grain, and cement mortar grain coated steel plates.
Classified by coating type, organic coatings can be made with different paints, resulting in PVC coated steel, polyester coated steel, acrylic coated steel, fluorocarbon coated steel, and silicone polyester coated steel.
Classified by coating performance, there are high weather resistance coating plates, high temperature coating plates, self-extinguishing coating plates, sterilization coating plates, non-stick snow coating plates, fingerprint-resistant coating plates, and self-lubricating coating plates.
Classified by special coatings and uses, there are epoxy zinc-rich coatings, cold rolled steel substrate organic coatings, surface flocked steel, and special machine-coated laminates, such as post-wood film boards, sandwich panels, and shock-resistant boards.
Selection of Coatings:
The coatings applied to colour coated coils are chosen based on the specific environmental conditions and intended use. Different resin types provide varying levels of durability and performance:
Users can select the appropriate coating based on their specific application needs, ensuring optimal performance and longevity of colour coated coils in diverse environments and industries.
Usage of different coating structures:
2/1: This single layer back coating has poor corrosion resistance and scratch resistance but offers good adhesion. It is mainly used for sandwich panels.
2/1M: This coating provides good corrosion resistance, scratch resistance, and molding properties, along with good adhesion. It is suitable for single-layer compression molding panels and sandwich panels.
2/2: Featuring double-layer back paint, this coating offers excellent corrosion resistance, scratch resistance, and processability. It is mostly used for single-layer pressboards, but its adhesion is not as strong, making it less suitable for sandwich panels.
