Common knowledges of Aluminum profiles bending processing:Ⅰ. Beijing Shengda Weiye Bending Company defines classification of aluminum profiles

1. By profile configuration: general profiles and thermally broken profiles 

2. By surface processing: anodized profiles and coating profiles.

3. By hardness: In the premise of (chemical composition) the same materials divided into aging sections (microstructure homogenization at high temperature) and non-aging sections.

4. By usage: industrial and residential construction

According to drawing and instructions to determine the profiles for the project. Balcony generally are anodized profiles. Doors and windows are normally thermally broken with coating profiles, material 6063 with hardness level T5.
