Reasons for leaving expansion joints during the installation of aluminum veneer curtain walls

When installing aluminum veneers, there will be certain expansion joints left. As a manufacturer of aluminum veneers in Weifang, let me take you to understand the reasons for leaving expansion joints during the installation of aluminum veneer curtain walls!

1. When installing the aluminum veneer curtain wall, the corner bracket needs to be fixed on the main and auxiliary keels, and the expansion gap position reserved during the production of the aluminum veneer curtain wall. Each aluminum veneer curtain wall needs to be fixed and installed firmly with at least 4 screws. But the diameter during installation will not be less than 10mm, so a gap needs to be left for easy installation.

2. Prevent the thermal expansion and contraction of aluminum veneer curtain walls during hot and cold weather. The raw materials for aluminum veneer curtain walls belong to non-ferrous metals, and pure aluminum is mostly 1100. However, metallic materials cannot prevent the correlation between thermal expansion and contraction. Leaving expansion joints in the middle of the aluminum veneer curtain wall can effectively prevent the compression deformation of the aluminum veneer curtain wall after summer expansion, as well as the tension between the aluminum veneer curtain walls due to sudden temperature drops, striving to achieve a balance between aesthetics and practicality.

3. Due to its beauty and elegance. Due to the fact that aluminum veneer curtain walls belong to customized specifications, differences in production processes, deviations in manufacturing specifications or processing techniques of manufacturers, or deviations in machinery and equipment, or technical problems of installers, it is often possible for aluminum veneer curtain walls to have large or small gaps after installation. Therefore, in order to be aesthetically pleasing, we leave even gaps to coordinate these scattered deviations.
