The system door and window is a system solution adopted by the system company to make a clear commitment to the performance and quality of the product. 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, sun shading, weather resistance, operation feel, etc. It also needs to consider the comprehensive results of the performance of various links of equipment, profiles, accessories, glass, viscose and seals. In accordance with the requirements of the overall solution, design, production, installation, and in actual use to achieve the promised performance, quality indicators of the product.

The core features of the five products of

system doors and windows: systematic design, high heat insulation profiles, standard material formulations, high-quality hardware systems, and rigorous production processes. The difference between the technical configuration of doors and windows of

1. system and ordinary doors and windows

system door and window group angle connection adopts special cast aluminum angle code with hollow stainless steel pin glue injection. This group angle process includes two special technologies: one is the expansion and tension fixing technology, and the other is the injection sealing technology. Each cast aluminum angle code is composed of two pieces of cast aluminum parts. When the stainless steel hollow pin is inserted, the two pieces of cast aluminum parts will automatically expand. With the matching tolerance of the angle code pin hole and the profile pin hole, the two 45-degree spliced profiles will be firmly tightened and fixed. After the fixing is completed, the next step is to inject glue into the angle code through the glue injection hole of the pin. After the glue injection is completed, the 45-degree splice of the profiles is completely sealed with glue from the inside of the cavity. The gap between the corner code and the profile cavity is also completely sealed.

ordinary aluminum alloy doors and windows generally do not deal with this part, or just symbolically apply glass sealant at the joint, which can be said to basically have no sealing effect. The doors and windows of the system have taken special measures in this part, and a stainless steel or aluminum alloy card with grooves is installed. On the one hand, the connection at the thin wall is strengthened to avoid the joint seam; On the other hand, the sealing of the splicing place is completely ensured by injecting glue between the stainless steel card and the profile.

The difference between 2. system doors and windows and ordinary doors and windows

1, stability and performance

System doors and windows have their own independent technical department, which will carry out strict tests and inspections on all parts of the system doors and windows, so all parts are well matched, it is not easy to fail, which is what we often say is good stability. Ordinary doors and windows are assembled by ordering different parts according to their own needs, but there will be some problems in the process of use, and the stability is relatively poor. After 2 to 3 years of research and development of the system doors and windows, the performance and quality of the materials, the entire doors and windows are comprehensively tested, and the mature products are launched after achieving the expected goals. Ordinary doors and windows are temporarily integrated doors and windows products for a single project, often without comprehensive testing.

2, Flexibility

All parts of the system doors and windows have been fixed according to different performances, and the selection margin is relatively small compared with ordinary doors and windows, so the flexibility is small. Ordinary doors and windows can be flexibly configured according to their own needs. System doors and windows are serialized and standardized products. Notch structure, material supply, etc. have strong exclusive and incompatibility. Series can only be selected according to the needs of the project, and individual projects are generally not developed. Ordinary door and window materials at home and abroad manufacturers can choose, can also be temporary mold, flexibility.

3, software aspect

system doors and windows not only provide products, but also provide design software, design manual, procurement manual, processing manual, professional special equipment and technical service support, which is a complete industrial chain. The quality of ordinary doors and windows depends on the level of designers and the ability of processing and installation of doors and windows enterprises.

4, after-sales service

The warranty period of system doors and windows is longer than that of ordinary doors and windows. The quality assurance of system doors and windows is not only the engineering warranty of door and window units, but also the service life warranty of system company products. In addition, brand stores can carry out simple maintenance. However, ordinary doors and windows are often after-sales without doors, and the owners do not know who to find for maintenance after the failure of doors and windows.
