PPGI is a material that is coated with one or more organic layers of organic coating based on galvanized sheet. It has good corrosion resistance, durability and aesthetics, and is widely used in construction, automobile, machinery and other industries.
Dual protection
The combination of a galvanised layer and an organic coating provides double corrosion protection. The galvanising layer effectively blocks moisture and oxygen from entering the steel, while the coating adds additional corrosion resistance, making it particularly suitable for long-term exposure to the environment.
Good processing performance
PPGI steel coils can be cut, bent, stamped and processed in a variety of ways, widely used in construction, automobiles and home appliances,easy to form and will not affect the quality of the coating.

Structure of Prepainted GI Steel Coil
*Topcoat (finishing) :which provides color, pleasing appearance and appearance and a barrier film to enhance long-term durability.
*Primer coat: to prevent undercutting of paint and enhance corrosion resistance.
*Pretreatment layer: applied for good adhesion and to enhance corrosion resistance.
*Base steel sheet:cold rolled steel sheet
How to choose PPGI?
- Coating Thickness
Different application environments require different thicknesses of galvanising and coating. For example, in coastal areas or areas with high levels of industrial pollution, thicker coatings and galvanising should be selected.
- Coating Quality
When selecting, it is important to ensure that the coating is uniform, has strong adhesion and is free from defects such as bubbles and cracks. The high-quality coating is key to ensuring the durability of steel coils.
Pre galvanized sheets are available in a wide range of colours and finish options to suit different architectural styles and design requirements.It fulfils the functionality of roofs and walls, and also adds visual aesthetics to the building.Pre coated gi sheet treated with coatings can resist various weather effects such as ultraviolet rays, acid rain, and moisture, and maintain stability and color durability in long-term use.
