In the field of building materials, color coated rolls and color coated steel plates, as two important surface treated steel plates, have attracted much attention due to their unique properties and wide application areas. In recent years, with the rapid development of industries such as construction, home appliances, and transportation, the demand for these two materials has also been continuously increasing. So, what is the difference between color coated rolls and colored steel plates? This article will provide you with a detailed interpretation.

1. Definition and Materials

1. Color coated roll: full name of color coated steel coil, English name is Prepainted Galvanized Steel Coils (PPGI). It is a product made by using hot-dip galvanized sheet, hot-dip aluminum zinc sheet, electroplated galvanized sheet, etc. as substrates, applying one or several layers of organic coating on the surface after surface pretreatment (such as chemical degreasing and chemical conversion treatment), and then baking and curing.

2. Color coated steel plate: also known as color coated steel plate, is a type of steel plate with an organic coating. It is usually made of cold-rolled steel plate as the substrate, and after degreasing, phosphating and other treatments, coated with a layer of epoxy primer and chemically resistant colored topcoat. Color steel plates can also be divided into various types such as veneer and color steel composite panels.

2. Structure and Performance

1. Color coated rolls: Due to the use of different substrates (such as hot-dip galvanized sheet, hot-dip aluminum zinc sheet, electroplated galvanized sheet) and coatings (such as polyester, silicon modified polyester, high durability polyester, polyvinylidene fluoride, etc.), color coated rolls have the characteristics of lightweight, beauty, corrosion resistance, and good weather resistance. Its coating can resist mechanical effects such as scratching, friction, collision, etc., and the coating and substrate can deform together without damage.

2. Color steel plate: Color steel plate also has excellent properties such as fire resistance, corrosion resistance, rain resistance, and corrosion resistance. It has high strength and stability, and is suitable for various building structures. In addition, color steel plates can be customized according to customer needs, with bright colors and beautiful appearance.

3. Usage and Application Fields

1. Color coated rolls: Due to their excellent performance and beautiful appearance, color coated rolls are widely used in various fields such as construction, home appliances, transportation facilities, advertising, electrical appliances, furniture, and transportation. For example, in the field of architecture, color coated rolls can be used for building roofs, exterior wall enclosure systems, and steel structure factories; In the home appliance industry, it can be used for the manufacturing of products such as refrigerator side panels.

2. Color steel plate: Color steel plates are also widely used in various fields, including construction, manufacturing, transportation, agriculture, and more. In the field of architecture, color steel plates can be used for ceilings, walls, insulation layers, stairs, road guardrails, partitions, and other parts; In the manufacturing industry, it can be used for the construction of logistics warehouses, factory buildings, equipment rooms, research centers, and other places.

4. Other differences

1. Appearance and color: There are also differences in appearance and color. Although the color of the color steel plate can also be customized, it may be relatively simple overall; The surface color of color coated rolls is usually more vibrant and diverse, and can be customized according to customer needs.
2. Processing performance: There are also differences in processing performance. Color coated rolls are more suitable for deep processing such as cold bending due to their good flexibility and formability; Color steel plates, on the other hand, focus more on their high strength and stability, and are suitable for various building structures.
In summary, there are significant differences between color coated rolls and color coated steel plates in terms of definition, material, structure, performance, and application fields. Both have their own strengths and jointly promote the diversified development of the building materials industry. In the future, with the continuous advancement of technology and the expansion of the market, the application prospects of color coated rolls and color steel plates will be even broader, bringing more possibilities and innovation space to various industries.
