Which is better PPGI and PCGI?

‌PPGI (pre-coated steel sheet) and PCGI (pre-coated color steel sheet) each have their own advantages, and choosing which one is better depends on specific usage needs and preferences. ‌

Both PPGI and PCGI are surface-treated steel sheets with excellent corrosion resistance and decorative properties, and are widely used in construction, home appliances, vehicles and other fields. The main difference between them is the coating. PPGI is mainly coated after galvanizing, while PCGI is directly colored on the substrate. Both materials have their own advantages:

‌PPGI‌: Due to its galvanizing-before-coating process, it has good corrosion resistance and durability, and is suitable for application scenarios with high requirements for coating durability. The galvanizing layer can provide basic protection, while the topcoat adds aesthetics and additional protection.

‌PCGI‌: Color coating is directly applied to the substrate, providing more color options and design flexibility, and is suitable for applications that require beautiful appearance, such as home decoration, billboards, etc. The color coating can directly provide the required color and design, and also has a certain degree of corrosion resistance.

Choosing PPGI or PCGI depends on the specific usage environment, aesthetic needs and cost considerations.
