Buyer Concerns (FAQ）
Q: How do you ensure color consistency across different batches?
A: We use advanced spectrophotometers for digital color matching against standard RAL codes, ensuring strict color control ($\mathbf{\Delta E \le 1.0}$) for seamless batch-to-batch consistency.
Q2: What paint thickness (PE/HDP/PVDF) should I choose for my project?
A: Standard 15–25 µm PE is ideal for ordinary indoor/outdoor cladding. For high-UV or coastal environments, we recommend 25–40 µm HDP or PVDF coatings for maximum color retention and corrosion resistance.
Q3: How do you prevent paint cracking or peeling during roll-forming?
A: Our PPGI utilizes premium flexible primers and topcoats tested for high elasticity ($\mathbf{\le 2T}$ Bending & MEK $\mathbf{\ge 100}$ wipes), ensuring zero cracking or delamination during deep profiling and bending.
Q4: What is the lifespan and weather warranty for your PPGI coils?
A: We offer tailored paint warranties (up to 20+ years) based on your coating selection (PE/HDP/PVDF), guaranteeing superior resistance against fading, chalking, and edge rust.
