Description of prepainted galvanized steel :
Color coated plate, also known as color steel plate, color plate. The color coated steel sheet is made of cold-rolled steel sheet and galvanized steel sheet as the base material. After surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating is applied in a continuous method (roller coating method), and baked and cooled Into a product. The coated steel plate has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed. It provides a new type of raw material to the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, and electrical industry. Wood, efficient construction, energy conservation, pollution prevention and other good effects.
Process flow :
The main production process of the common two-coat two-bake continuous color coating unit process is: uncoiling machine --------- stitching machine ----- press roller ----- tension machine --- -Unrolling looper ----- Alkali-eluting fat -------- Cleaning ---- Drying -------- chromating-------- Drying -------- Early Coating ------- Initial coating drying ------- Topcoat fine coating ------- Topcoat drying ----Air-cooled cooling --- winding work Set ----- Rewinder ----- (The next roll is packed into the warehouse).

Characteristics of prepainted galvanized steel :
The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color coated sheet. In addition to the protective effect of hot-dip galvanized sheet, the organic coating on the surface also plays a role of insulation protection and rust prevention, and its service life is longer than that of hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180g / m2 (double-sided), and the maximum galvanized amount of the hot-dip galvanized substrate for external use is 275g / m2.
Allowable deviation of color coated steel plate and steel strip (mm):

Product Application :
Color-coated steel plate using galvanized steel as the base material, in addition to zinc protection, the organic coating on the zinc layer serves as a cover and isolation, which can prevent the steel plate from rusting and has a longer service life than galvanized steel. According to the coating, The service life of the steel sheet is 50% longer than that of the galvanized steel sheet. However, in different regions and different places of use, the service life of color-coated boards with the same zinc plating amount, the same coating and the same coating thickness will vary greatly. For example, in industrial areas or coastal areas, due to the effect of sulfur dioxide gas or salt in the air, the corrosion rate is accelerated, and the service life is affected. In the rainy season, the coating is wet by rain for a long period of time, or in places where the temperature difference between day and night is too large, and it will be corroded quickly, and the service life will be reduced. Buildings or workshops made of color-coated steel plates often have a long service life when they are often washed by rain, otherwise they will be affected by the effects of sulfur dioxide gas, salt and dust. Therefore, when designing the roof, the greater the slope of the roof, the less likely it is to accumulate dirt and other dirt, and the longer the service life; those areas or parts that are not often washed by rain should be washed regularly with water.
