Product parameters
| Item | Industry General Requirements | Remarks |
| Stiffener Configuration | Install when the short side > 600mm, with spacing ≤ 500-600mm, using U-shaped aluminum channels. | Prevents panel bulging and deformation; must be firmly riveted/welded to the panel. |
| Bracket Specification | Commonly used 2.5mm thick aluminum brackets, arranged at intervals ≤ 350mm from the panel. | Connects the panel to the keel; must meet pull-out resistance requirements. |
| Joint Width | Generally 10-15mm, filled with weather-resistant silicone sealant. | Reserves allowance for thermal expansion and contraction to prevent panel deformation and extrusion. |
Production Process of PVDF Coated Aluminum Veneers
01
Pretreatment
Prior to coating, aluminum sheets undergo degreasing, decontamination and chemical treatment to form a chromate film, enhancing coating adhesion and weather resistance.
02
Primer Coating
Seals the substrate, improves penetration resistance and topcoat uniformity, with a typical dry film thickness of 5-10μm.
03
Topcoat Coating
Provides decorative color, protects the metal surface from aging and corrosion, with a typical dry film thickness of 23-30μm.
04
Clear Coat Coating
Enhances erosion resistance and metallic luster while protecting the topcoat, with a typical dry film thickness of 5-10μm.
05
Curing Process
Secondary curing at 180-250℃ for 15-25 minutes to ensure stable coating performance.
06
Sheet Metal Fabrication
Cut, folded, bent, welded and polished into custom shapes and sizes as required for construction projects.
07
Coating Application
Available in two methods: manual spraying (custom color selection) and roller coating (suitable for mass production).
08
Quality Inspection
Finished products are inspected in accordance with PVDF coating standards for building curtain walls to ensure compliance.
Application scenario
Commercial building facade, Airport facade

FAQ
1
Q: What is the service life of aluminum veneer curtain walls?
A: Exterior PVDF coated aluminum veneers offer over 20 years of weather resistance under normal conditions, meeting international curtain wall standards for color stability and coating adhesion.
2
Q: Are aluminum veneer curtain walls waterproof and leak-proof?
A: With proper structural design and sealing, they provide excellent water resistance. Custom drainage system designs are available to meet high-rise building requirements.
3
Q: What is the fire performance of aluminum veneers?
A: Aluminum substrates are non-combustible (Class A fire rating). Combined with flame-retardant coatings, they meet building curtain wall fire codes for public and high-rise buildings.
4
Q: What installation methods are available?
A: Common methods include dry hanging, hook-on, and back bolt systems. We support both concealed and exposed frame curtain wall systems to suit different building structures.
5
Q: Are they suitable for coastal, high-corrosion environments?
A: Yes. Enhanced pretreatment, high-weatherability PVDF coatings, and anti-corrosion processes improve salt spray resistance for coastal and industrial environments.
6
Q: What special shapes can be achieved?
A: Through bending, welding, perforation and engraving, we can create arcs, double curves, hollow designs and complex custom shapes for unique building facades.
7
Q: Do you provide curtain wall system design services?
A: Yes. We offer one-stop services including scheme optimization, detail design, and installation guidance to support full project execution with design institutes.
8
Q: How is color difference controlled?
A: Standardized coating processes ensure color consistency within industry tolerances. Pre-production color sample confirmation is available for key projects to guarantee on-site uniformity.
