Aluminum profile after a series of surface process treatment, has good corrosion resistance, not afraid of moisture, not afraid of sunlight, high temperature deformation, low temperature not embrittered, not burning, not aging, durable stability, suitable for all kinds of climate environment. The quality of profile directly decides the pros and cons of doors and windows, the strength of doors and windows of inferior profile production is low, extremely easy to change color, deformation.
2. The structure of doors and windows
The outstanding advantages of heat insulation aluminum alloy doors and windows are multi-cavity structure, good insulation, good drainage performance, good fire resistance, good atmospheric corrosion resistance, high comprehensive performance, long service life. Common aluminum alloy doors and windows because of the performance than insulation broken bridge is poor, so its service life is relatively short.
3. Configuration of doors and windows
Hardware is the main factor that determines the quality of the whole window. The quality of door and window hardware accessories largely determines the service life of doors and windows. It can be said that door and window hardware is the "heart" of the entire door and window, including handles, lock cores, hinges, etc., each of which plays an important role.
Three points by technology, seven points by quality, production equipment and technology level also affects the overall performance of doors and windows. High quality aluminum alloy doors and Windows, fine processing, smooth tangent, consistent angle, good sealing performance, switch freely.
