The installation is simple and convenient, and is more conducive to the installation of negative angle curtain walls. 6. In this application, since the vertical purlins with negative inclination angles are relatively high, in addition to bearing vertical forces, they also have to bear horizontal forces. Generally, the vertical purlins of curtain walls made of aluminum profiles cannot meet the force requirements. Therefore, a steel frame is used to ensure the force requirements.
