Product Description
Product Description:(Three-dimensional luminous word aluminum coil) is a kind of pre-coated aluminum coil, which is specially used to make outdoor three-dimensional luminous signs
Lightweight: 2.7 g/cm³ density, easy to install in the air or on glass curtain walls.
Formability: It can be cold-bent into complex letter shapes (such as arcs, edges and corners), and seamlessly spliced.
Weather resistance: The coating is resistant to ultraviolet rays and rain erosion, and is suitable for environments from -30°C to 80°C.
Core Benefits:
All-weather durability:
PVDF coating has a life of 15-25 years and is resistant to UV yellowing (e.g. Florida strong sun test).
Efficient Processing:
CNC bending machine direct forming, reducing the need for welding (seam ratio <5%).
Lighting Optimization:
The highly reflective coating (≥80%) improves the utilization rate of LED light sources and reduces energy consumption by 30%.
Environmental Compliance:
Lead-free in accordance with EU RoHS standard, 100% recyclable (UL ECOLOGO certification in the United States).

Features
With its light weight, high reflectivity and weather resistance, Channel Letter Aluminum Coil has become the core material for commercial signage in Europe and the United States and urban landmarks in Asia. For example, 3003-H14 PVDF-coated coil dominates neon signage in New York's Times Square, while 5052 alloy hard oxide is used for luxury signage in Dubai's extreme climate. Its integration of digital processing (laser cutting + CNC bending) and sustainable design (100% recyclable) is promoting the global outdoor advertising to upgrade in the direction of high efficiency, energy saving and art.
