PPGI vs. PPGL – How to Choose?

PPGI (Pre-Painted Galvanized Iron) and PPGL (Pre-Painted Galvanized Steel) are steel sheets coated with a protective layer, known for their excellent rust resistance, aesthetics, and wide range of applications, making them an ideal choice for industries such as construction, home appliances, and automotive. Whether you're a builder or a manufacturer, PPGI/PPGL can provide an economical and high-performance solution for your needs.

1. PPGI/PPGL Specifications, Materials, and Sizes

PPGI/PPGL comes in a variety of specifications, with common sizes including:

• Thickness: 0.12mm to 1.5mm (e.g., 0.3mm, 0.5mm, 1.0mm).
• Width: 600mm to 1500mm (e.g., 1000mm, 1250mm).
• Length: Typically in coil form, with lengths customized to customer requirements.

Base Materials:

• Galvanized Iron (GI): Base material is galvanized steel, suitable for general rust resistance needs.
• Galvanized Steel (GL): Base material is galvanized steel with aluminum, offering better rust resistance for highly corrosive environments.

Coating Types:

• Polyester Coating (PE): Economical and practical, suitable for general construction and home appliances.
• Silicone-Modified Polyester Coating (SMP): Better weather resistance, ideal for outdoor construction.
• Fluorocarbon Coating (PVDF): Excellent weather and corrosion resistance, suitable for high-end construction and industrial applications.

2. PPGI/PPGL Production Process and Workflow

1. Base Material TreatmentCleaning and surface treatment of galvanized or galvanized-aluminum steel sheets to ensure coating adhesion.
2. Coating ProcessCoating is applied using roller or spray coating methods.The coating is cured at high temperatures to form a uniform and dense protective layer.
3. Surface TreatmentEmbossing: Adds surface texture for enhanced aesthetics.Film Lamination: Protects the coating surface from scratches during transportation and installation.
