PPGL (Pre-Painted Galvalume) refers to color-coated steel sheets that undergo factory pre-painting before forming. Also known as pre-coated or coil-coated steel, these products typically use hot-dip galvanized steel sheets as their base material.
The term GL traditionally stands for Galvalume steel (55% Al-Zn alloy coated steel). Unlike batch-dipped products, modern GL specifically denotes continuously hot-dipped Al-Zn alloy coated steel sheets. PPGL represents the pre-painted version of these Galvalume products.
The hot-dip coating process can also produce steel sheets with various metallic coatings including:
- Pure aluminum coatings
- Zinc-aluminum alloy coatings
- Zinc-iron alloy coatings
- Zinc-aluminum-magnesium alloy coatings
While GL is sometimes broadly used to describe different hot-dip metal-coated steels, it technically refers specifically to galvanized products. Similarly, PPGL may occasionally serve as a general term for various pre-painted metal-coated steels, but most accurately describes pre-painted Al-Zn alloy coated steel.
All these metallic-coated steel variants can undergo factory pre-painting to become PPGL products, combining corrosion resistance with decorative finishes.
