With the continuous improvement of the quality of life, people have higher requirements for the quality and performance of housing, and pay more and more attention to the energy-saving performance, safety performance, hiccup noise reduction, aesthetics, comfort, and durability of building doors and windows. When purchasing door and window products, in addition to paying attention to the quality of the materials, glass, accessories, etc. of doors and windows, people pay more attention to the realization of a comprehensive performance after the combination of door and window components.

The quality of doors and windows is mainly affected by the quality of materials and hardware, while the performance of aluminum alloy doors and windows is mainly affected by the structure. When purchasing aluminum alloy doors and windows, it is not only important to look at the thickness of the material and the strength of the hardware accessories, but more importantly, the structure. The popular system windows in recent years are derived from traditional doors and windows in structure, thus achieving better performance than traditional aluminum alloy doors and windows. Many door and window brands can do material wall thickness and hardware accessories, but the real test of a door and window brand’s technical strength is still the structure.
Corner structure:
The corner joints of windows are the main bearing points and sealing points of windows. If the strength of the corner joints is not high enough, it will cause cracks and deformation at the joints, causing leakage of doors and windows, and causing safety hazards, which will seriously affect the sealing performance and safety of doors and windows. SUNRAY system doors and windows use Italian imported flying curtain cutting machines with an accuracy of 0.03MM. The window sash corners use active corners, and use pin corners to assemble the corners. High-strength and precise bolts are used for connection. The active corners do not damage the cavity of the aluminum profile (the external dimensions will not be distorted), avoiding the problem of the fourth corner offset. After tightening the screws, inject special corner glue, which is strong and waterproof. The central link (also called the central link) of the window, like the corner joints, is an important part of the window frame. The quality of the central column link will seriously affect the sealing and safety of the window. The central column link of SUNRAY doors and windows uses a special connector for cast aluminum injection, which can effectively prevent the center support from shifting and flipping.
Cavity structure:
Thermal insulation and sound insulation are not only related to the glass structure, but also closely related to the aluminum profile structure. SUNRAY system doors and windows adopt multi-cavity broken bridge aluminum structure and special multi-layer sealing design, which improves the water and air tightness of doors and windows to a certain extent, and greatly reduces the indoor and outdoor heat conduction caused by air convection. The broken bridge design of broken bridge aluminum can effectively reduce heat transfer and effectively improve the thermal insulation performance. The thermal insulation effect is more than 5 times that of ordinary doors and windows. On the basis of the broken bridge aluminum design, SUNRAY system doors and windows use national-level 6063 aluminum ingot T6 Guangya aluminum profile + automotive-grade EPDM strips to create a more durable and sealed high-quality door and window system that meets the strict performance standards of Europe.
Use self-developed insulation strips to connect the insulation area, while maintaining the best mechanical properties, prevent direct heat conduction, minimize the thermal conductivity, optimize the insulation efficiency, reduce energy consumption, and maintain a comfortable indoor temperature.
Drainage structure:
Rainwater that seeps into the cavity from the outside must be discharged as quickly as possible to avoid accumulation. SUNRAY system doors and windows break through the traditional horizontal drainage method. The drainage holes adopt a vertically downward hidden drainage method, which makes drainage smoother and reduces rainwater accumulation.
Hardware system:
No matter how well the windows are sealed, they still need to be opened for ventilation. Functional requirements such as anti-theft, anti-mosquito, and anti-falling, including opening, are all achieved by the hardware system. An excellent hardware system can achieve its own functions without affecting other performances of doors and windows.
