What is Aluminum Trim Coil?
Aluminum trim coil is a specially designed aluminum coil product for architectural exterior decoration. It protects building structures from natural environmental corrosion, enhances building aesthetics, offers stable performance, and requires low maintenance. Compared to regular aluminum coils, it features smaller volume and lighter weight.
The aluminum trim coil primarily uses 3000 series alloys (such as 3105) in H-28 temper to balance strength and workability. Surface treatments are selected based on application requirements, including coatings (Poly/PVC), anodizing, or dual-tone designs.
Why Choose Aluminum Trim Coil?
- Exceptional Durability: Corrosion/rust-resistant, adaptable to all climates
- Lightweight: Easy installation, ideal for elevated applications
- Versatility: Multiple specifications for diverse project needs
- Maintenance-Free: No repainting required; simple cleaning suffices
- Eco-Friendly: 100% recyclable, aligning with green building principles
