Aluminum is the best aluminum profiles door & window and deep processing supplier. 
1. We use high quality thermally broken raw materials as insulation bars. By adding an insulation bar to aluminum profiles, we form an insulation barrier to prevent heat transfer from outside and inside. The material of the insulation bar is PA66 nylon, which has good toughness and strength. Therefore, it has a good insulation effect.
2. A wide variety of finish options are available for your different coating requirements. Powder coating, anodizing and wood grain finishes are the most popular choices for extruded aluminum door & window frames.
Established over 11 years ago, our company has been one of China's best aluminum profile suppliers. And since 2011, when we started exporting our products, we have become one of the best suppliers in the world.
