When it comes to aluminum profiles for doors, windows, and façades, surface treatment is one of the most important factors. Different markets—especially in the Middle East—have unique preferences for color consistency, corrosion resistance, and durability. Here are the most common finishing options:
1. Anodizing
Colors: Silver, champagne, bronze, black
• High hardness and corrosion resistance
• Premium appearance
• Very popular in the Middle East, especially sand silver & champagne

2. Electrophoresis Coating
• Bright, glass-like surface
• Often used for high-end window & door systems
3. Powder Coating
Colors: White, black, brown, grey, etc.
• Strong weather resistance
• Cost-effective
• The most widely used finish in Gulf countries
4. Thermal Break Profiles
• PA66 insulation strips reduce heat transfer
• Better energy efficiency
• High demand in Qatar, Oman, and Saudi Arabia due to extreme temperatures
5. Wood Grain Finish
• Ideal for interior doors and sunrooms
• Highly realistic texture options
6. PVDF Coating
• UV resistance up to 25+ years
• Preferred for high-rise building façades
