The Difference between National Standard Aluminum Profiles and European Standard Aluminum Profiles

At present, aluminum products was sold on the market  by aluminium profile suppliers include GB aluminum profiles and European standard aluminum profiles (up to the European standard oxidized surface). The difference between the two profiles is mainly in the cross-sectional shape and profile slots.

The major difference between GB aluminum profiles and European standard aluminum profiles is that:

1. Different corner chamfer profiles, GB corners of four corners profile is very small, basically a right angle. The four corners of the European standard profile have large arc chamfers.

2. The groove type differs. Different nuts are placed in the profile groove when the profile is fixedly connected. The national standard profile groove is placed with a regular square nut, and the European standard profile element is placed with a special profiled nut.
