Aluminum alloy doors and windows believe that many families will use, because of its good sealing, no rust, no fading, no shedding, and long service life. Therefore, it is favored by many families. The lack of aluminum alloy in the daily life of every person is the lack of doors and windows. But, should choose what kind of aluminum alloy door and window is suitable, is the best? What are the purchasing skills? In this, small make up to give you a brief introduction of aluminum alloy doors and windows to choose three ways.
1、 Door and window materials
The material selection of aluminum alloy doors and windows generally includes: aluminum profile (main material, auxiliary material), glass (tempered glass) and hardware accessories, etc. when general decoration owners choose doors and windows, they often pay more attention to the wall thickness of main materials and auxiliary materials and the thickness of glass, but the requirements for hardware accessories are not very high, which is unscientific. In fact, the national requirements for aluminum alloy doors and windows are standard. Generally, the wall thickness of aluminum alloy doors and windows should not be less than 1.2mm. Generally, the thickness of aluminum products of general merchants is up to the standard. Only some businesses fail to meet the requirements when ordering aluminum materials. Xiaobian suggested that you must have vernier caliper to measure the thickness of aluminum when selecting aluminum alloy doors and windows. Relative to the wall thickness and glass aluminum alloy doors and windows hardware accessories (screws, hinges, pulleys, etc.) requirements should also be understood, stainless steel hardware accessories are certainly better than aluminum accessories, and pulley is load-bearing, so it is recommended to choose double pulley, such products have high quality, good wear resistance, long life, smooth push and pull, not easy to damage. In addition, aluminum alloy doors and windows with insulating glass are required to be used in the selection, and good reputation, good brand and good sealing performance must be selected on the adhesive strip, so as to achieve perfect sound insulation effect, and at the same time, it can avoid the storage of dust and small garbage and wind resistance.
2、 Production identification
In the purchase of door-to-door windows, consumers must pay attention to the production identification, certificate, environmental protection and other labels of aluminum alloy doors and windows products, because the current market is full of substandard products that have not been tested at all, resulting in a lot of quality conditions. Therefore, the aluminum alloy doors and windows without clear marks should not be cautious.
3、 Product process
Pay attention to the workmanship of aluminum alloy doors and windows. Some high-quality aluminum alloy doors and windows products must be sealed by special technology to prevent rainwater penetration and other problems, and the details are also refined; on the contrary, those with quality problems, whether in appearance or structure, are made very rough, and all aspects of performance are not up to the national standards.
Although the price of aluminum alloy doors and windows is directly related to the price of aluminum ingot, the price realized by doors and windows in the same period is relatively stable. Generally speaking, the price of high-quality doors and windows is about 30% higher than that of poor quality doors and windows. Poor quality doors and windows usually use aluminum profiles made of recycled aluminum and waste aluminum containing a large number of impurities. The wall thickness is generally about 0.6-0.8mm. Both tensile strength and elasticity are greatly lower than the relevant national regulations. High quality aluminum products are generally about 1.2-1.4mm, and even some high-end brands Its wall thickness of 1.6, 1.8, 2.0 mm is better, of course, the price will not be low.
