What is PVDF Coating
PVDF is a fluoropolymer that is polymerized from vinylidene fluoride monomers. Its stable chemical structure provides excellent resistance to chemical corrosion, UV rays, and harsh weather conditions. PVDF is currently the highest-end outdoor anti-corrosion and weather-resistant coating in the field of color-coated steel sheets. Thanks to its ultra-long service life and superior durability, PVDF coating has become the preferred material for construction and industrial projects worldwide.
PE/PVDF/SMP/HDP Coating
PE, SMP, HDP and PVDF are four mainstream surface coatings for color coated steel roofing sheets. They differ in weather resistance, color retention, corrosion resistance, service life and cost.
- PE is cost-effective but has moderate durability and resistance, suitable for indoor applications.
- PVDF offers the highest performance in terms of durability and resistance, making it ideal for commercial and industrial settings.
- SMP provides a balance between cost and performance, suitable for various industrial applications.
- HDP enhances the properties of standard polyester, making it suitable for outdoor architectural uses where durability is essential.
| Coating Type | Weather Resistance | Color Retention | Corrosion Resistance | Service Life | Price |
| PE | Low | Ordinary | General | 5-8 years | Lowest |
| SMP | Medium | Good | Medium | 10-15 years | Medium |
| HDP | High | Very Good | High | 15-20 years | High |
| PVDF | Highest | Outstanding | Best | 20-30+ years | Highest |
PPGI PVDF Roofing Sheets VS PPGL PVDF Roofing Sheets
The core difference between PPGI and PPGL PVDF roofing sheets lies in the coating of their base steel substrate. PPGI roofing sheets meet the needs of ordinary buildings, whereas PPGL is preferred for projects with higher anti-corrosion protection requirements.
- PPGI PVDF Roofing Sheets adopt hot-dip galvanized steel as the base material. They feature stable coating protection, good ductility and excellent bending performance. Suitable for conventional building roofing projects, these sheets present full and uniform color finish, serving as universal high-end color-coated steel roofing materials.
- PPGL PVDF Roofing Sheets are made of steel substrate with 55% aluminum-zinc alloy coating. With a superior protective coating system, they provide excellent moisture resistance and corrosion resistance. Ideal for buildings in rainy and high-humidity environments, they enjoy stable paint film adhesion and better overall durability, making them perfect for high-standard outdoor roofing applications.
PPGI/PPGL PVDF Roofing Sheets For Sale
The pricing of PPGI/PPGL PVDF Roofing Sheets is generally determined by substrate, surface treatment, coating thickness, specifications and other factors. Wanzhi Group owns two galvanized steel production lines with zinc coating weight ranging from 30g to 275g per square meter and an average monthly output of 10,000 metric tons. We guarantee to supply cost-effective, high-quality products for customers’ construction projects.
PVDF Roofing Sheet Advantages And Applications
Advantages
- Super Strong Weather Resistance and Aging Resistance: The fluorocarbon coating has a stable structure that resists strong ultraviolet radiation, making it less prone to fading, chalking, or cracking during long-term outdoor use.
- Excellent Corrosion Resistance: Resistant to acids and alkalis, salt spray, and industrial gas erosion, it has a longer lifespan in coastal, humid, and heavily polluted environments.
- Outstanding Self-Cleaning Properties: The smooth and hydrophobic surface makes it difficult for dust to adhere, allowing rainwater to easily wash it clean, resulting in low maintenance costs over time.
- Strong Adhesion of Coating Film: Resistant to impact and scratching, the paint does not easily peel off during bending processing, with stable performance against wind and rain erosion outdoors.
- Lightweight and High Strength: Lightweight with a low structural load, it supports large-span roofs; it can be used with profiled trapezoidal tiles, corrugated tiles, and concealed fastener roof panels, adapting to curved, irregular, and three-dimensional architectural shapes, while allowing for convenient construction.
Application
- Coastal buildings and seaside factories in high salt spray areas.
- Buildings resistant to acid and alkali corrosion in heavy industrial and chemical pollution zones.
- Large public buildings such as stadiums, airports, and convention centers.
- High-end commercial buildings and villa roofs/exterior walls.
- Warehouses, industrial workshops, and various steel structure roofing projects.
