Explore Our PPGI & PPGL Series

PPGI (Pre-Painted Galvanized) and PPGL (Pre-Painted Galvalume) steel coils are manufactured by applying multiple layers of organic coatings onto zinc or aluminum-zinc coated steel substrates. This continuous coil coating process results in a product that perfectly balances the structural strength of steel with exceptional corrosion resistance and a durable, aesthetically pleasing finish.

Whether you require standard color-coated steel coils for roofing and cladding or highly durable prepainted galvalume steel for harsh industrial environments, Luyuan Steel delivers consistent quality. Every coil is produced to precise specifications and backed by full English Mill Test Certificates.

Applications of PPGI & PPGL Steel

Sıkça Sorulan Sorular

  • What is the main difference between PPGI and PPGL?

    The primary difference lies in the base metal. PPGI uses a hot-dip galvanized (zinc-coated) steel substrate, offering excellent basic corrosion protection. PPGL uses a galvalume substrate (coated with 55% aluminum, 43.4% zinc, and 1.6% silicon), which provides superior heat reflectivity and significantly higher corrosion resistance, especially in harsh or coastal environments.

  • How do I choose between PE and PVDF coatings?

    PE (Polyester) is the most common and cost-effective coating, ideal for standard roofing and cladding in moderate climates. PVDF (Polyvinylidene Fluoride) is a premium coating that offers exceptional resistance to UV radiation, chalking, and chemical exposure. PVDF is highly recommended for projects in tropical, coastal, or heavy industrial areas where long-term color retention is critical.

  • Can you match custom colors outside the standard RAL chart?

    Yes. While we offer the full standard RAL color chart, we can also perform custom color matching based on physical samples or specific brand color codes provided by the client. We ensure high color consistency across different production batches.
