System doors and windows are a perfect organic combination of performance systems. It needs to consider a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, shading, weather resistance, and operating feel. It is necessary to consider the comprehensive results of the performance of equipment, profiles, accessories, glass, adhesives, and seals, all of which are indispensable, and finally form high-performance system doors and windows.

1. Stability and performance

The system doors and windows have an independent technical department, which will carry out strict testing and inspection for each component to ensure the stability of the doors and windows. After 2 to 3 years of research and development of system doors and windows, the materials, the performance and quality of the entire doors and windows are comprehensively tested, and mature products are launched after reaching the expected goals.

Ordinary doors and windows are assembled by ordering different components according to their own needs. Due to various factors such as different quality and performance of each component, the stability during use is relatively poor; and they are temporarily integrated doors and windows for a single project. Products are often not fully tested.

2. Flexibility

The doors and windows of the system are serialized and standardized products. Each component has been fixed according to different performances. The notch structure and material supply are highly exclusive and incompatible. The series is selected according to the needs of the project, with flexibility. Small, but now is the era of customization, the system doors and windows can completely design suitable door and window products according to customer needs.

Ordinary doors and windows can be configured with components according to their own needs. Door and window materials can be selected by domestic and foreign manufacturers, or they can be temporarily opened. The flexibility is strong, but their quality and standardization cannot be guaranteed.

3. Software and after-sales service

System doors and windows not only provide products, but also provide design software, design manuals, procurement manuals, processing manuals, professional equipment and technical service support, which is a complete industrial chain. In terms of after-sales service, the quality assurance of system doors and windows is not only the engineering quality assurance of the door and window unit, but also the lifetime quality assurance of the system company's products. In addition, brand stores can carry out simple repairs.

The quality of ordinary doors and windows depends on the level of designers and the processing and installation capabilities of door and window enterprises, and they are relatively insufficient in terms of support and follow-up services. At the same time, ordinary doors and windows are often sold without doors. After the doors and windows fail, the owner does not know who to call for maintenance.
