1. Because the amount of overlapping fan frames is not appropriate; Aluminum guardrails can be adjusted by external and internal hexagonal screws supported by lower bearings, and the internal hexagonal screws can be angled to achieve the purpose of correction.
2. The solution to the displacement or position of the glass pad and the deformation of the window sash glass due to gravity is to reinstall the PVC guardrail gasket using the correct scientific method. Sometimes external damage caused by window sash deformation can be avoided. Deformation is caused by reinstallation and strict adherence to correct operating methods and standard specifications.
3. The diagonal deviation of the frame fan is too large, far exceeding the allowable deviation, mainly caused by cutting or welding. This artificial adjustment has little effect, and the PVC guardrail that needs to be cut needs to be redone.
4. Aluminum door guardrails cannot reach the windows and are prone to using inferior hardware for doors and windows.
5. The installation bracket of the aluminum gate guardrail is installed at an angle, and when it occurs, there is no vertical inspection of the offline and pedestrian windows to avoid the influence of errors.
