Smooth Surface Blue PPGI Steel Coils
Smooth surface blue PPGI steel coils are renowned for their pure, luminous color expression, maximizing the aesthetic appeal of blue. Featuring a perfectly flat, smooth surface with uniform coating, they offer selectable gloss levels from matte to high-gloss to suit project requirements.

- Varying shades of blue impart a modern, clean, and technologically advanced aesthetic to buildings.
- The smooth surface resists staining effectively, restoring its pristine appearance with simple rainwater runoff.
- The coating exhibits excellent ductility, minimizing cracking during processing.
Applications
- Roofing and wall panels for large venues, office buildings, and technology parks.
- Premium appliance housings (e.g., air conditioners, water heaters), commercial vehicle bodies and components.
- Environmental and water facilities such as water treatment plants and pump stations.

Textured Surface Blue PPGI Steel Coil
