Commercial and industrial roller shutter systems are typically painted using the powder coating method to improve durability and provide an attractive finish.
Powder coating offers a wide range of colors that can match the architectural style of buildings and surrounding environments. It is available in both matte and glossy finishes, and customized colors can also be produced.
Why Powder Coating is Used in Roller Shutters
Powder coating provides excellent protection for metal surfaces and significantly improves the lifespan of roller shutters.
This coating technology offers:
- Impact resistance
- Scratch and abrasion resistance
- Protection against harsh environmental conditions
Roller shutters used in high cycling or high-speed environments benefit greatly from powder coating because it improves long-term durability.
Powder Coating Production Process
The powder coating process typically includes several steps:
- Cleaning the metal surface
- Surface preparation
- Powder coating application
- Oven curing
The coated components are cured in industrial ovens that can process long elements up to 9–10 meters. Powder guns ensure that the coating covers every curve of the metal surface evenly.
Benefits of Powder Coating
Powder coating offers many advantages for roller shutter systems:
- Wide range of colors
- Increased durability and longer service life
- Corrosion resistance
- Impact resistance
- Abrasion resistance
- High resistance to dirt accumulation
- Easy maintenance
- Smooth coating without drips
- Heat reflective properties
- UV resistance
- Chemical resistance
- Smoother finish compared to conventional coatings
