Advantages of HDP Color-Coated Steel
- Strong Weather Resistance: Its UV resistance surpasses that of ordinary PE coatings, effectively controlling color shift and fading over time and making it suitable for most outdoor architectural applications.
- High Cost-Effectiveness: While priced lower than high-end PVDF paint coatings, it also offers excellent chemical and abrasion resistance, meeting the performance requirements of mid- to high-end architecture.
- Excellent Processability: The coating offers strong adhesion and flexibility, making it suitable for various shearing, bending, and deep-drawing processes, while remaining resistant to cracking.
- Wide Application Range: The mature process allows for easy processing, making it suitable for a wide range of applications requiring high weather resistance, such as industrial plants and commercial buildings.
Applications of HDP Color-Coated Steel
| Processed Products | Main Application Areas | Application Examples |
| Color Coated Profile Sheet | Industrial/Logistics Buildings | Roofs and exterior walls of factories, warehouses, workshops, and temporary buildings |
| Metal sandwich panels | Commercial/Residential Buildings | Cold storage, shopping mall partitions, office buildings, gymnasiums, and airport auxiliary buildings |
| Printed steel coils (wood grain, stone grain) | Construction/Home Appliances/Automotive | Exterior wall decoration, roofs, partitions, ceilings, cabinet panels, appliance housings, and automotive interior and exterior trim |
| Color-coated flat sheets | Furniture/Home Appliances | File cabinets, lockers, office partitions, kitchen cabinets, refrigerator/washing machine/air conditioner housings |
| Building accessories | Architectural Decoration | Awnings, downspouts, ventilation ducts, and interior ceilings |
HDP VS PVDF
Both HDP and PVDF are weather-resistant, but PVDF is more weather-resistant. Of course, PVDF is also the most expensive. HDP is the most cost-effective material, meeting most building requirements. PVDF is considered high-end and is used for projects that require extreme durability and quality.
| Items | HDP | PVDF |
| Chemical Composition | Modified polyester resin, more stable molecular structure | Polyvinylidene fluoride resin, extremely chemically inert |
| Weather Resistance | Excellent | Excellent (gold standard) |
| Color Retention | Good (10-15 years) | Excellent (over 20 years) |
| Chemical Resistance | Good, resistant to general contamination and cleaning agents | Extremely strong, resistant to strong solvents and severe chemical contamination |
| Flexibility & Processability | Excellent, strong adhesion, easy deep drawing and bending | Good, but aggressive processing may damage the coating |
| Cost | Medium | High |
| Main Applications | Standard industrial plants, logistics warehouses, commercial buildings, home appliances | High-end landmark buildings, airports, stadiums, hospitals, high-end office buildings, coastal structures |
