Advantages of Color Coated Steel PPGI Color Coated Sheet

 

PPGI sheet is short for pre-painted galvanized steel sheet. It is a kind of pre-painted steel sheet, which uses galvanized steel sheet as the base metal. Then it is painted with one or several layers of organic coatings after surface pretreatment (degreasing and cleaning), and then baked and solidified continuously. Then the coils will be cut into sheets of the desired size. Through rolling equipment, the plain sheets can be profiled into corrugated PPGI sheets.

The GI color coated sheet we produce has characteristics of long service life, easy installation, high strength, and beautiful appearance. That's why it is getting popular among investors.

 

1. Light Weight
The weight of colored GI sheets ranges from 1 to 10 kg/m2, which is about 1/30 of a brick wall. According to the weight calculation formula: Thickness (mm) * 1 m * 1 m* 7.85 = (kg/m2), the PPGI sheet weight per sqm mainly depends on the thickness. Therefore, the weight of our GI color coated sheet is available from 1.099 kg/m2 (0.14*1*1*7.85) to 9.42 kg /m2 (0.14*1*1*7.85). So its shockproof performance is better, which makes the building safer. Besides, it is easy to transport to save your cost.

 

2. High Strength
Colour coated GI sheet keeps the mechanical properties of steel, including bending strength, elongation, tensile strength, etc. It is still tough and durable to use. The application of the coating is to protect its surface from rusting and make it good-looking.

3. Beautiful Appearance
The colour coated steel sheet is pretty, which means there is no need for extra decoration. Moreover, the color can keep for many years.

 

4. Flexible and Quick Installation
It is fast and easy to install if using colored galvanized sheets as building materials. On the one hand, it can shorten the construction period by more than 40%. On the other hand, there is no need for a deep foundation, which is good for the environment.
