Common abnormal patterns of the window system.

Abnormal pattern	Code	Abnormal situation description
Rust	01	The body or accessories of the window may contain metal products, which may cause unsightly appearance when rust is generated or may be inconvenient to switch when used.
Water leakage	02	Water leakage is usually caused by factors such as aging of waterproof materials, poor installation, and deformation of the outer frame. When the situation is slight, the indoors are wet, and when the situation is serious, the building body may be damaged due to leakage.
Water-repellent material shedding	03	Water-repellent material shedding is usually caused by factors such as aging or improper use
Glass rupture	04	Glass rupture is usually caused by external factors, which may cause personal injury. In this case, new products need to be replaced. If it is a special glass, it must be contacted by the manufacturer for replacement.
Window frame deformation	05	Possible reasons for the deformation of the window frame include poor material quality, improper gap filling, and external force effects, which may result in poor window adhesion and inconvenient switch.
Screw rust	06	The long-term exposure of the screw to air or humid environment is prone to chemical reactions and gradually loses its fixed function for a long time, which is likely to cause damage to the window.
The damage of window-sliding lock	07	The damage of window-sliding lock results from improper use or aging
The damage of screen window	08	The damage of the screen window or its frame results from improper use or aging
