ppgi prepainted galvanized steel coil green
Color coated prepainted steel ppgi coil is a type of color coated steel plate. It is a product made by applying paint by roller coating method, then baking and cooling after conversion treatment. The production process has evolved from one coating and one drying to two coatings and two drying. There is also a three-coating and three-baking process. There are many colours of color-coated boards, such as white grey, sea blue, orange, sky blue, crimson, brick red, ivory white, porcelain blue, etc. The surface state of ppgi colour coated sheets can be divided into ordinary coated boards, embossed boards and printed boards. The market uses of PPGI galvanized steel coils are mainly divided into construction, home appliances and transportation.
Ppgi prepainted galvanized steel coil is widely used and has the characteristics of no pollution, weather resistance, corrosion resistance, and high processability. Ppgi prepainted steel coil is widely used in various industries such as construction, home appliances, packaging, machinery, and more. It is involved in different aspects like processing, transportation, interior decoration, medical and automotive.
The usage rate of steel ppgi coil in home appliances is 31%, and its use in construction accounts for 63%. It is indispensable in the construction industry. It is used less in other aspects, about 6%. Galvanized steel sheets are used as substrates for coatings that provide protection and isolation functions. This prevents rusting and extends the service life of the steel plate by 50%, while also providing stronger protection.
In different regions and parts of use, even if the same amount of galvanizing, paint and ppgi steel sheet green with the same coating thickness are used, their service life is more different. In industrial and coastal areas, exposure to sulfur dioxide or salt in the air accelerates corrosion and reduces service life. During the rainy season, the coating will corrode rapidly after being wetted by rain for a long time, thus reducing its service life.
Buildings and factories made of green color roofing sheets can extend their service life if they are often washed away by rain. If the necessary precautions are not taken, they will become more vulnerable to sulfur dioxide, salt, and dust. Therefore, when designing, the slope of the roof should be increased. The larger it is, the less dust and other dirt accumulates and the longer its service life is. Parts and areas that are not frequently washed by rain should be cleaned regularly.
