Click to get today's price list!
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.
PPGL Coil uses DX51D+AZ, q195, and galvalume steel sheet as the substrate, PE coating is our most commonly produced, it can be used for up to 10 years. We can also customize the color of the PPGL steel coil, such as wood grain, or matt.
The Galvalume coating typically consists of 55% aluminum, 43.4% zinc, and 1.6% silicon, which offers superior protection compared to traditional galvanized steel.

FAQ
Q: 1.Which environment is suitable Prepainted Galvalume Steel
A: 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.
Q: 2.Prepainted Galvalume Steel vs. Prepainted Galvanized Steel
A: They are all based on cold-rolled steel sheets.
PPGI Coil is prepainted on cold-rolled steel sheets after galvanizing, and PPGL steel is prepainted on cold-rolled steel sheets with an alloy of 55% aluminum and
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.
Q:3. PPGL Coil Price in China
A: The main factors affecting the price of PPGL are the price fluctuations of steel raw materials, the thickness, and width of the substrate, the type of coating, the thickness of the coating, and the weight of the zinc layer.
