The main differences between ‌PPGI and ‌PPGL are their substrate and coating types, and the resulting differences in performance and application areas. PPGI is a pre-painted galvanized steel plate, while PPGL is a pre-painted galvalume steel plate. Here is a detailed comparison between them:

Substrates and coatings

PPGI: It uses galvanized steel plate as the base material and the surface is covered with colored paint.

PPGL: Aluminum-zinc alloy steel plate is used as the base material, and the surface is covered with colored paint.

Performance and application areas

PPGI: Due to its good corrosion resistance and low cost, it is widely used in construction, home appliances, billboards and other fields.

PPGL: It has better corrosion resistance and heat resistance, and is suitable for higher demanding occasions, such as automobile manufacturing, home appliance casings, etc.

Price and market

PPGI: The price is relatively low and suitable for customers with limited budget.

PPGL: More expensive, but due to its superior performance, is a better choice for applications requiring greater durability.

Production process

PPGI: The steel sheet is first galvanized and then colored paint is applied to it.

PPGL: Steel panels are treated by hot-dip galvanizing and then coated with colored coatings.

Select suggestions

Choose the appropriate material based on the needs of the application. If the application environment is harsh or requires higher corrosion resistance, PPGL may be a better choice. For general applications or situations where budget is limited, PPGI can meet the needs and cost less.

To sum up, the main differences between PPGI and PPGL are their substrates, coating types, performance characteristics and application areas. The choice of material depends on specific application needs and cost considerations. ‌
