As the core surface material of aluminum-plastic panels, colored aluminum (pre-coated aluminum panels) promotes industry upgrades with its comprehensive performance. The core advantages and typical applications are as follows:

I. Core advantages

High weather resistance and color durability

Adopting fluorocarbon (PVDF) or nano-coating, it is resistant to ultraviolet rays, acid rain and temperature changes, with a color difference ΔE≤2 (ASTM G154 test), and an outdoor service life of more than 20 years. For example, the aluminum-plastic panel curtain wall of Sanya Phoenix Airport uses colored aluminum surface layer, which has no fading or cracking in the tropical marine climate for 10 years.

Lightweight and strength adaptation

The thickness of colored aluminum is 0.2-0.5mm, combined with polyethylene core material, the self-weight of the plate is ≤5.5kg/m², and the bending strength is more than 80MPa, which is suitable for the exterior walls of high-rise buildings (such as the special-shaped curved aluminum-plastic panels of Shenzhen Ping An Financial Center).

Flexible processing and environmental protection

Support punching, bending, and arc processing to meet personalized design needs. The material is 100% recyclable, and the carbon emissions of the production process are 30% lower than those of traditional aluminum panels, meeting LEED certification standards.

Economical and easy to maintain

The overall cost is 40% lower than that of pure aluminum curtain walls, the surface is oil-repellent and hydrophobic, and the cleaning efficiency is increased by 60%. The exterior wall of a commercial complex in Hangzhou uses colored aluminum-plastic panels, saving more than 150,000 yuan in annual maintenance costs.

2. Typical application scenarios

Building exterior walls: office buildings, hotels (such as the renovation of the Shanghai World Financial Center).

Advertising logos: large outdoor light boxes (wind pressure resistance and weather resistance suitable for highway billboards).

Interior decoration: shopping mall column covering, elevator car (imitation wood grain colored aluminum-plastic panels instead of solid wood).

Transportation facilities: subway platform walls, high-speed rail station interiors (fireproof A2 grade core material + colored aluminum surface layer).

Colored aluminum continues to expand the application boundaries of aluminum-plastic panels through "coating innovation + composite structure", becoming an economical and efficient solution for modern building skins.
