1. Q: Why is RAL 3020 (Traffic Red) so popular in construction?
A: RAL 3020 is a highly recognizable, bright red widely used in brand logos, industrial rooftops, and safety features. It provides excellent visual guidance. We use an automated color matching system to ensure that the color difference between different batches is less than 0.5%, avoiding color variations during large-area application.
Q: Is this vibrant red prone to fading?
A: Red pigments are sensitive to UV light, so we have specifically optimized the paint formulation for RAL 3020. If your project is located in an area with strong UV radiation, we recommend using HDP (High Durable Polyester) or PVDF (Fluorocarbon) coatings to ensure no significant chalking or fading for 15-20 years.
2. Q: What substrate do you use for your RAL 3020 PPGI?
A: We typically use hot-dip galvanized steel coils (HDGI) conforming to ASTM A653 or EN 10346 standards as the substrate. Steel grades range from commercial grade (DX51D) to high-strength structural grade (S550GD), and zinc coating thickness can be customized from Z30 to Z275 upon request.
Q: What is the typical coating structure?
A: The standard specification is 2/1 (two front, one back) or 2/2 (two front, two back). The front side typically consists of a 5μm primer + 15-20μm topcoat, while the back coating is a 5-12μm protective coating selected depending on the application environment.
Q: Do you support customized processing (such as slitting or leveling)?
A: Yes. We have a professional processing line that can slit steel coils into narrow strips or cross-cut them into PPGI sheets of specific lengths according to your needs. We also support applying a surface protective film to prevent scratches on the paint surface during processing.
