PVDF Color Coated Aluminum Coil Common Alloys and Tempers
The core of the PVDF color coated aluminum coil is the aluminum alloy itself. The alloy determines how strong or flexible the coil will be.
1xxx Series: Industrial Purity
Alloys like 1100 or 1050 are almost pure aluminum. They are very soft and easy to bend. These are often used for simple decorative parts or flashing where high structural strength is not required.
3xxx Series: The Standard Choice
Alloy 3003 and 3105 are the most popular for prepainted aluminum. They offer good strength and excellent corrosion resistance. These are widely used for roofing and siding.
5xxx Series: High Strength & Marine Grade
Alloys like 5005 and 5052 are much tougher. They are ideal for high-end facades and architectural projects in coastal areas because they resist salt spray perfectly.
Temper (Hardness)
We offer various tempers such as H14, H24, H16, and H26. The “H” state tells you how much the metal has been hardened. For example, H24 is “half hard” and offers a great balance between strength and bending ability.
Comparison with PE Coating
| Feature | PVDF Coating | PE Coating |
|---|---|---|
| Coating thickness | ≥ 25 microns | ≥ 18 microns |
| Weather resistance | 20–30 years | 10–15 years |
| UV resistance | Excellent | Good |
| Cost | Higher | Lower |
| Best for | Exterior, high-end | Interior, budget projects |
| Color retention | Superior | Good |
| Warranty period | 15–30 years | 5–10 years |
PVDF Color Coated Aluminum Coil PVDF vs. PE
When buying color coated coils, you will often choose between PVDF and PE (Polyester). Here is why PVDF is usually the superior choice for outdoor use.
Coating Performance Comparison
| Feature | PE (Polyester) | PVDF (Fluorocarbon) |
|---|---|---|
| Outdoor Warranty | 5 – 10 years | 20 – 30 years |
| UV Resistance | Moderate | Excellent |
| Color Retention | Fades over time | Stays vibrant for decades |
| Chemical Resistance | Low | High (Acid & Alkali resistant) |
| Price | Lower | Higher |
| Best For | Indoor / Signs | Exterior Walls / Roofing |
Diverse Product Types and Finishes
Our PVDF color coated aluminum coil comes in many “looks” to suit different architectural styles.
Solid and Metallic Colors
The most common finishes are solid colors (White, Grey, Blue) and metallic colors (Silver, Gold, Champagne). Metallic finishes contain tiny flakes that reflect light, giving the building a premium, high-tech look.
Wood Grain and Stone Patterns
Using advanced printing technology, we can make aluminum look like natural oak, walnut, marble, or granite. This allows architects to achieve a “natural” look with a material that is fireproof and lightweight.
Brushed and Embossed Coils
Brushed finishes provide a textured, industrial feel. Embossed coils (like orange peel or stucco patterns) increase the surface area and provide extra rigidity and slip resistance.

FAQ: Frequently Asked Questions
PVDF Color Coated Aluminum Coil Product and Quality Questions
What is the lifespan of PVDF coating?
In normal outdoor environments, PVDF color coated aluminum coil will maintain its color and integrity for over 20 years. Some high-spec coatings last over 30 years.
Can I get a custom color?
Yes. We can match any color from the RAL or Pantone charts. We can also match a physical sample provided by the client.
Is the coating flexible enough for bending?
Absolutely. The coating is designed to be flexible. It will not crack or peel when the aluminum is bent into shapes (T-bend test results are usually 0T to 2T).
Logistics and Ordering
What is the MOQ (Minimum Order Quantity)?
Generally, for a specific color and size, the MOQ is 2 to 3 metric tons. This depends on the specific alloy and width.
How do you protect the coil during shipping?
Each coil is wrapped in plastic film, then waterproof paper, and finally secured on a wooden pallet with steel straps. This is “Eye-to-Sky” or “Eye-to-Wall” packing.
Do you provide samples?
Yes, we can provide A4-sized color chips or small coil samples for quality testing and color approval.
