PVDF (Polyvinylidene Fluoride) color coated steel coils represent the premium tier of prepainted steel products. PVDF coating, commonly known as Kynar 500® or Hylar 5000®, contains 70% PVDF resin and 30% acrylic resin, providing exceptional weather resistance, UV stability, and color retention for 20-30 years in outdoor applications.
Unlike standard PE or SMP coatings, PVDF offers superior resistance to chalking, fading, chemical corrosion, and pollution. Ideal for monumental architecture, coastal buildings, airports, stadiums, and high-end industrial facilities where long-term aesthetics and minimal maintenance are critical. Available in a full range of RAL colors with custom matching.

All PVDF coils are manufactured under ISO 9001:2015 certified quality management system on dedicated color coating lines with precise temperature and speed control. Testing includes: dry film thickness measurement (DFT gauge, per ASTM D7091), color measurement (spectrophotometer, ΔE≤1.0 per CIELAB), gloss measurement (60° geometry, per ASTM D523), T-bend flexibility (per ASTM D4145), pencil hardness (per ASTM D3363), MEK solvent resistance (100+ double rubs), impact resistance (per ASTM D2794), and salt spray testing (1000+ hours, per ASTM B117).
Surface Protection: Each coil is protected with a removable PE protective film (50-70μm) on the top surface to prevent scratching during transport and fabrication. Edge protection rings on both coil sides.
Packaging: Waterproof kraft paper + plastic film wrap + circumferential steel strapping (minimum 4 straps). Wooden pallet or steel cradle base. Eye-to-sky or eye-to-wall loading per customer requirement. Maximum 2 coils per 20ft container.
Storage: Store in dry, ventilated warehouse. Avoid outdoor exposure before fabrication. Coils should be used within 6 months for optimal forming performance.
