As a professional manufacturer of aluminum windows and doors based in Shandong, China, Mingjue is committed to providing high-quality, high-performance and customizable aluminum alloy door and window products for global customers. Our products are crafted with advanced production technology and premium raw materials, integrating excellent structural performance, aesthetic design and practical functionality, and are widely applied in residential buildings, commercial complexes, industrial facilities and various architectural projects.

Mingjue aluminum windows and doors are manufactured with high-grade 6063-T5 and 6061-T6 aluminum alloy profiles as the core raw materials. Through precision extrusion, numerical control processing, surface treatment and professional assembly, the finished products combine the inherent advantages of aluminum alloy with humanized structural design. We only select aluminum alloy profiles that meet national and international high standards, and strictly control the material performance to ensure the stability, durability and safety of each set of doors and windows.
The grade classification of our aluminum alloy profiles is based on the tensile strength, yield strength and elongation in accordance with GB/T 5237 and ISO 7593 international standards, which directly determine the load-bearing capacity, anti-deformation performance and service life of doors and windows.

The main differences between 6063-T5 and 6061-T6 aluminum windows and doors lie in structural rigidity, anti-corrosion performance and mechanical strength.
6061-T6 profiles have higher alloy content and better heat treatment performance, with superior anti-deformation and impact resistance, which allows for more optimized section design under the same load-bearing requirements and achieves a more lightweight and aesthetic appearance.
For example: For the same size of casement window with a frame width of 70mm, the 6061-T6 aluminum alloy profile can bear a glass load of up to 80kg, while the 6063-T5 profile can bear a glass load of 60kg, which fully meets the different design and use requirements of low-rise and high-rise buildings.
· Series: Refers to the nominal width of the door and window frame profile (unit: mm), which is the core parameter determining the structural width, sealing performance and load-bearing capacity of doors and windows. Our mainstream series include 55, 65, 70, 80, 90 and 110 series, which are applicable to different building types such as ordinary residential, high-end residential and commercial buildings.
· GF (Glass Factor): Refers to the matching ratio of glass thickness to profile cavity, which is the key index for ensuring the thermal insulation, sound insulation and anti-wind pressure performance of doors and windows. Mingjue strictly matches the glass specification according to the profile series and use environment, and the GF value is controlled within the optimal range of 0.8-1.2 to ensure the perfect combination of glass and profile.
For Mingjue 6063-T5 and 6061-T6 aluminum alloy doors and windows, the matching glass specifications and performance parameters under the same series are different, which can meet the customized needs of different regions and building heights:
