1. Wide range of applications

Color-coated steel plates are widely used in construction, home appliances, packaging, machinery and other industries due to their pollution-free, weather-resistant, corrosion-resistant and high processability. In addition, color-coated steel plates also involve processing, transportation, interior decoration, medical equipment and automobile industries.

2. Application distribution

Color-coated steel plates account for 31% of the application in the field of home appliances and 63% in the field of construction, and are an indispensable part of the construction industry. Other applications account for about 6%. Coated steel plates based on galvanized steel plates have protection and isolation functions, which can prevent rust and extend the service life by 50% compared with traditional materials, while providing stronger protective performance.

3. Differences in service life

Even if the amount of galvanizing, paint and coating thickness are the same, the service life of color-coated steel plates will vary depending on the region and purpose. In industrial areas and coastal areas, exposure to sulfur dioxide or salt in the air will accelerate corrosion and shorten the service life. In the rainy season, long-term exposure to humid environments will also cause rapid corrosion and shorten durability.

4. Buildings and factories using pre-coated steel panels

For structures built with pre-coated steel panels, frequent rain washing helps to extend their service life. Otherwise, they are more susceptible to damage from sulfur dioxide, salt and dust accumulation. Therefore, it is recommended to increase the roof slope during the design stage - the greater the slope, the less dirt and dust will accumulate, thus extending the service life.
