Popularization of knowledge on aluminum alloy doors and windows from material selection to acceptance

1、 Aluminum alloy

The first step in understanding high-end aluminum alloy doors and windows is to first understand the types of aluminum alloys and distinguish between ordinary aluminum alloys and bridge broken aluminum alloys. Ordinary aluminum alloys do not have insulation strips, but only have adhesive treatment on the surface, which does not provide insulation and does not save energy; During installation, only about 1mm ordinary angle aluminum is used to connect with rivets, which has low cost and poor firmness and safety. The broken bridge aluminum alloy, on the other hand, has a combination of energy-saving and thermal insulation strips, which can play a role in preventing rapid or slow heat transfer by interrupting the middle of heat transfer. The wall thickness profile is above 1.4mm, and a complete set of equipment is assembled through doors and windows using specialized inserts with a thickness of 3mm or more at the corners; Structurally, it is more complex and costly than ordinary aluminum doors and windows.

2、 Glass

The glass component accounts for the largest area in aluminum alloy doors and windows, so the selection of glass material is also a key factor in showcasing the quality of high-end aluminum alloy doors and windows. In addition to the requirements for the ornamental value of glass, there are also requirements for its insulation and energy conservation. The commonly used glass for aluminum alloy doors and windows in general residential buildings includes tempered glass, laminated (laminated) glass, low-e glass, coated glass, etc,

The thickness of ordinary single glass is 5mm, while hollow glass generally has a interlayer of 6mm and 5mm single glass on both sides, which is also commonly used in high-end aluminum alloy doors and windows.

3、 Hardware accessories

High end aluminum alloy doors and windows not only use high-quality profiles in the main materials, but also pay more attention to product quality in details such as hardware accessories. The hardware accessories of aluminum alloy doors and windows mainly include pulleys, linkage handles, and hinges. Hardware accessories can be judged based on simple surface gloss and paint uniformity. Choosing smooth and glossy hardware accessories is also more flexible when used. If you want to judge the quality of hardware accessories at a deeper level, you can start with the material and technology, check whether the pulley is used smoothly and flexibly, whether the handle bears enough weight, and whether the hinge material is rust proof. Because doors and windows often face wind and rain directly, it is necessary to choose high-quality brand products, otherwise subsequent replacement will waste more time and energy.

4、 Acceptance

After understanding some knowledge points of high-end aluminum alloy doors and windows, when choosing a brand, one can be more confident. During acceptance, only the following aspects need to be considered: attention should be paid to the surface of doors and windows without obvious damage or scratches, adjacent components should not have obvious color differences on the coloring surface, and the surface of doors and windows should be smooth, flat, and clean. The more high-end aluminum alloy door and window brands pay attention to these small details, and good profile quality can also be reflected through surface details.
