Prepainted Galvalume Steel Coil for Roofing Contractors – Super High Durable Polyester available.
Prepainted Galvalume Steel Coil(PPGL) is a type of steel product that has been coated with a layer of aluminum-zinc alloy (Galvalume) and then pre-painted with a layer of protective paint.
The Galvalume coating typically consists of 55% aluminum, 43.4% zinc, and 1.6% silicon, which offers superior protection compared to traditional galvanized steel. The prepainting process involves applying a primer and topcoat, which can be customized in various colors and finishes to meet specific design requirements.

Here are the common questions that you may want to know.
Prepainted Galvalume Steel is suitable for various environments due to its excellent corrosion resistance, durability, and aesthetic appeal. Here are some environments where it is particularly well-suited:
Coastal Regions: The aluminum-zinc alloy coating provides excellent protection against saltwater corrosion, making it suitable for coastal and marine environments.
Extreme Weather Conditions: It can withstand extreme weather conditions, including heavy rain, snow, and high winds, making it suitable for regions with harsh climates.
Corrosion Resistance:
- Galvalume Steel: Offers superior corrosion resistance, especially in environments with high humidity and exposure to saltwater. The aluminum in the coating provides a barrier to corrosion.
- Galvanized Steel: Provides good corrosion resistance, but it is generally less effective than Galvalume in harsh environments. The zinc coating sacrifices itself to protect the steel.
Applications:
1. Prepainted Galvalume Steel:
- Commonly used in roofing, siding, and other building materials where long-term durability and resistance to the elements are crucial.
- Ideal for coastal and industrial environments due to its superior corrosion resistance.
2. Prepainted Galvanized Steel:
- Suitable for general-purpose applications where the environment is less corrosive.
