First, aluminum alloy doors and windows profiles
Main components: aluminum alloy profiles are mainly based on aluminum profiles, adding some alloying elements to enhance strength and hardness. Common types of aluminum alloy are aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum titanium alloy, aluminum zinc alloy and aluminum rare earth alloy.
Raw materials and processing: the general raw materials are aluminum ingots, which are melted into aluminum rods and then extruded into aluminum bars for doors and windows by heating. The service life of the processed aluminum alloy profile can reach more than 30 years.
Broken Bridge Aluminum Alloy: Broken Bridge Aluminum Alloy profile is the use of PA66 nylon heat insulating strips connecting the two ends to form a heat insulating layer, which can effectively reduce the heat transfer, and play the role of heat preservation and energy saving.
Second, the advantages of aluminum alloy doors and windows
Corrosion resistance: aluminum alloy doors and windows have good corrosion resistance and are not easy to rust with long-term use.
Weather resistance: good weather resistance, can adapt to various climatic environments.
Environmental protection: no formaldehyde and other harmful substances, in line with national energy conservation and environmental protection policies.
Heat preservation and insulation: superior thermal insulation performance, especially the broken bridge aluminum alloy doors and windows can significantly improve the effect of heat preservation and insulation.
Diversified colors: different color styles can be realized according to the interior design and exterior wall design to meet the different needs of customers.
