Product Advantages & Key Features
01 PIN GLUE INJECTION PROCESS
Fill the gap between the aluminum and corner code to guarantee superior structural strength.
02 Multi Cavity Insulation Strip
PA66 high thermal insulation strip is used to completely block the heat conduction path of the profile.
03 Concealed Drainage Design
Effectively avoids the possibility of rainwater backflow and ensures seamless water exit.
Adopt High Strength Profile and Strict Production Process
The structural design is firm, and the wind pressure strength is far better than plastic steel windows and ordinary aluminum alloy windows. It can withstand high wind pressure to ensure the safety performance of doors and windows in wind and rain weather, especially suitable for coastal cities and other areas subject to severe weather.
High-quality Sash windows feature a four-side compression sealing design. When the window sash is closed, it is firmly pressed against the surrounding sealing strips on the window frame. Compared to conventional Sash windows that rely on lateral sealing via wool strips, this design offers superior air tightness and water tightness, enabling more effective prevention of air and rainwater infiltration. As a result, it enhances thermal insulation performance, reduces energy consumption, and provides improved wind pressure resistance.
Customization Available: If you want to customize different sizes and materials, we can provide a customization service for you with a minimum order quantity of just 1.

Extreme Performance & Testing Standards
A temperature difference environment ranging from -30℃ to +70℃ is simulated in an artificial climate chamber, and the temperature distribution and heat flow dynamics on the inner and outer surfaces of doors and windows are continuously monitored.
Simulate a 12-level typhoon (wind speed ≥32m/s) + heavy rain (flood volume ≥4L/㎡·min) in the wind tunnel laboratory.
Thermal insulation to reduce heat conduction: The use of thermal insulation broken bridge aluminum alloy profiles can effectively reduce the heat conducted through the doors and windows, so that the indoor temperature is more stable, warm in winter and cool in summer.
Energy saving: In winter, a window frame with insulation strips can reduce the heat lost through the window frame by 1/3; in summer, it can reduce energy loss more, reduce heating and cooling costs, in line with the concept of energy conservation and environmental protection.
U Value < 2.2 W/(㎡·K)
The three-layer insulating low-e glass and our whole welding technology enhance the integrity of the frame and reduce heat dissipation from the seams.
Corrosion resistance: Passed the 240-hour neutral salt spray test, suitable for high-humidity coastal areas.
Weather resistance: After 4000 hours of QUV accelerated aging test, the light retention rate is over 90%, and the color stability far exceeds that of ordinary paint (no fading or yellowing for 5-10 years).
