The building steel structure enclosure system currently uses a large number of colored profiled steel plates. Rolled steel sheet is a type of sheet made of 0.4-2.0mm thick color coated steel sheet (hereinafter referred to as color coated sheet), which is cold-formed into wave shaped, V-shaped, U-shaped and other shapes by a forming machine. Color coated sheet is generally made of hot-dip and electroplated substrates, and is coated with one or more layers of organic coatings on a continuous unit by roller coating or film coating, and then baked and cooled to form it. Therefore, it is sometimes also called baked paint sheet. Coatings come in different colors, hence they are also known as colored coated steel plates.

The design selection of colored profiled steel plates should be based on the requirements of corrosion resistance, design service life, aesthetic lifespan, durability, processing method, and deformation degree of the usage environment. Clear regulations should be made for the grade, substrate mechanical properties, substrate type and coating weight, coating type and thickness, plate thickness, color, profiled plate type, and connection form of the colored coated plate.

Structural designers should fully understand the basic physical structure of color coated panels and the basic performance and functions of each physical structural layer in order to make appropriate choices.

The beautiful pressed color steel plate has clear lines in dozens of colors, which can meet the needs of any style of activity room building and achieve satisfactory results.

◆ Anti static color coated board

Anti static color coated plate is a type of steel plate that adds conductive materials to a regular polyester coating, turning the original insulating coating into a semiconductor coating and changing the surface resistance to 10 ° -10 ° Q. The ordinary polyester coating has a surface resistance of about 1013Q, and with the installation of the grounding wire in the project, the static electricity generated on the surface of the color coated steel plate due to air convection and clothing friction can be introduced into the ground and disappear, preventing the coating from adsorbing dust and bacteria and reducing its performance, causing electrostatic discharge and other hazards. It is mainly used in anti-static, high cleanliness dust-free, and sterile places, such as the electronic semiconductor industry, food processing industry, pharmaceutical industry, hospitals, etc.

Ma'anshan Iron and Steel Co., Ltd. (hereinafter referred to as Ma'anshan Iron and Steel) is a super large steel joint venture in China, located on the banks of the Yangtze River, with a superior geographical location and convenient transportation, known as the "flower of Jiangnan". Ma Steel is a joint enterprise group with a production scale of over 18 million tons of steel. Its products, including cold-rolled galvanized sheets, color coated sheets, H-beams, wheel rims, high-speed wire rods, and steel bars, not only meet the needs of * *, but are also exported to more than 50 countries and regions.

Ma Steel built two color coated plate production lines with an annual output of 300000 tons in 2004. This production line is currently one of the most advanced continuous coating units for two coating and two drying rolls. The production technology and main equipment are introduced from FATA company in Italy, and the products can be widely used in construction, home appliances, furniture, and transportation

Transportation and other industries. Products produced according to standards, including American, Japanese, and European standards, are distributed throughout the country and reach countries such as Poland, Israel, Saudi Arabia, Norway, Sweden, and Spain.

◆ Ordinary polyester (PE)

Ordinary polyester coated color coated board, with ordinary polyester coating as the front topcoat, and a warranty period of '-10 years under normal conditions. This product is reasonably priced, has good durability, and can meet the usage requirements of ordinary buildings.

Ordinary polyester(PE)

◆ Easy to clean color coated board

Easy to clean color coated board adopts special coating, with excellent anti fouling performance on the surface, which can resist the penetration of pollutants into the paint film, and has good rainwater self-cleaning function; It can reduce the pollution of industrial waste gas, automobile exhaust, oil fume, dust and other pollutants to buildings, and reduce the maintenance costs of manual cleaning of buildings in the later stage

The substrate of color steel plate is cold-rolled substrate, hot-dip galvanized substrate, and electroplated galvanized substrate. The types of coatings can be divided into polyester, silicon modified polyester, polyvinylidene fluoride, and plastic sol. The surface state of color steel plates can be divided into coated plates, embossed plates, and printed plates. Color steel plates are widely used in industries such as building appliances and transportation. For the construction industry, they are mainly used for roofs, walls, and doors of industrial and commercial buildings such as steel structure factories, airports, warehouses, and refrigeration. Color steel plates are less commonly used in civil buildings.

Substrate type and coating weight: Substrate type and coating weight are important factors affecting the corrosion resistance of color coated plates, and should be selected based on factors such as usage, environmental corrosiveness, service life, and durability. Outdoor color coated panels are usually made of hot-dip galvanized/aluminum zinc coated substrates, which increase the weight of the coating and correspondingly improve the corrosion resistance. For example, in areas with severe industrial pollution or humid coastal areas, it is recommended to use substrates with a galvanized layer weight of 180g/m or more. Ordinary hot-dip galvanized substrates can be used for indoor decoration or household appliance color coated panels. Coating type: The coating on color coated plates is a key factor affecting their effectiveness. When selecting materials, the appropriate type of coating should be determined based on different applications, environmental factors, and lifespan requirements. Taking coastal humid areas as an example, it is recommended to use color coated plates with high coating durability (such as P ν DF, HDP, etc.); In areas with severe industrial pollution, not only should the corrosion resistance requirements of color coated plates be considered, but also the pollution resistance performance of coatings, such as choosing P ν DF color coated plates, easy to clean coating color coated plates, etc.
