Features & Advantages

1. Superior Coating Performance

PVDF Coating: Based on PVDF resin with fluorine content over 60%, featuring C-F bonds with bond energy up to 500 kJ/mol. It offers exceptional weather resistance, UV resistance, acid-alkali resistance, and salt spray resistance, maintaining stable color for over 20 years in harsh environments such as coastal high-salt-fog areas and industrial pollution zones. The coating has a pencil hardness of ≥2H, adhesion of ≥1 level, and excellent self-cleaning performance with low surface energy (18-22 mN/m), making pollutants hard to adhere.

PE Coating: Made of polyester resin, with good decorative performance, high gloss, and rich colors. It is cost-effective, with a service life of 10-15 years in temperate climates, suitable for general outdoor and indoor roofing projects. The coating adopts a single-layer baking process at 200-220℃, ensuring good processability and flexibility.

2. Optimal Thickness Design
3. Excellent Aluminum Substrate Properties
4. Easy Installation & Low Maintenance
5. Environmental Protection & Recyclability

Production Process

Aluminum Substrate Selection: High-quality aluminum alloy coils are selected and inspected to ensure uniform thickness and stable performance.

Surface Treatment: The substrate is degreased, pickled, chromated, and dried to remove impurities and form a protective film, enhancing coating adhesion.

Coating Application: PE coating adopts single-layer roller coating; PVDF coating adopts double coating and double baking process (primer + topcoat), with precise control of coating thickness.

High-Temperature Curing: PE coating is cured at 200-220℃; PVDF coating is cured at 230-250℃ to form a stable and dense coating film.

Cooling & Cutting: The coated aluminum coil is cooled to room temperature, then cut into sheets of specified width and length according to customer requirements.

Quality Inspection: Each batch of products undergoes strict inspection (coating thickness, adhesion, color difference, flatness, etc.) to ensure compliance with standards.

FAQ

Q1: Can you provide customized colors and surface finishes?
A1: Yes, we support customization according to RAL color code, Pantone color, or customer-provided samples. Surface finishes such as matte, high-gloss, wood grain, and stone grain are also available.
Q2: What is the difference between PE and PVDF coatings? Which one should I choose?
A2: PE coating is cost-effective with good decorative performance, suitable for general outdoor projects in temperate climates. PVDF coating has superior weather resistance and corrosion resistance, suitable for harsh environments (coastal, industrial areas) and projects requiring long service life. You can choose according to your project location, budget, and service life requirements.
Q3: Can you provide samples?
A3: Yes, free samples (1-2 pieces) are available for quality inspection. The customer only needs to bear the shipping cost.
Q4: Can you customize the thickness, width, and length?
A4: Yes, we can customize thickness (0.3mm-3.0mm), width (30mm-2650mm), and length (2m-12m) according to your specific project needs.
