Based on the internal comparison data, aluminum composite material (ACM), commonly known as Dibond, is superior to PVC (often called Sintra) for outdoor signage, particularly in demanding climates.
Key reasons why aluminum composite is the better choice include:
- Durability: ACM is rated as high durability because it resists dents, corrosion, and warping. In contrast, PVC has moderate durability and is prone to warping in the heat or becoming brittle and cracking in extreme cold.
- Weather Resistance: While PVC offers good resistance, it may discolor over time. Aluminum composite provides excellent weather resistance, featuring UV stability and wind resistance that withstands temperatures as low as -40°C.
- Lifespan: An ACM panel typically lasts 10–15 years (and up to 20 years with proper care). PVC signs generally show wear and require replacement within 5–8 years.
- Maintenance: Aluminum composite requires minimal upkeep, usually just occasional cleaning. PVC is categorized as low maintenance but may require periodic replacement sooner than ACM due to environmental wear.
