1. Look at the brand
The reason why a brand can become a brand, popularity is one thing, but consumers choose ten aluminum alloy doors and windows not because of its popularity, but because of its quality assurance. At present, broken bridge aluminum of the material brands in the market mainly include fengaluminum, Central Asia, Asian aluminum, Xingfa, Weiye, Weichang, Xinhe and other domestic first-line brands of aluminum, and there are also Shide, conch, jinpeng and other second-line aluminum brands, and even some low-priced Miscellaneous brands or so-called fake German brand aluminum. If you want to buy a good Broken Bridge aluminum doors and windows, the first step is that the aluminum brand must be selected. Aluminum of different grades and different wall thickness will affect the price of the entire Broken Bridge aluminum doors and windows. Choose domestic first-line broken bridge aluminum brand materials, such as fengaluminum, Central Asia, Asian aluminum, Xingfa, Nanshan, etc., or domestic large factories with a certain scale of strength, owners can also Baidu the top ten domestic aluminum materials, large aluminum enterprises such as the top 20, the aluminum produced by big brand factories are all tested and qualified in terms of flatness, gloss, film thickness, material wall thickness, material compressive properties, etc.
2. Look at the product
From the surface of the profile, the surface of the good Broken Bridge aluminum profile is glossy and textured, and the color treatment on the surface will also be natural, and it feels smooth when looking at it. However, profiles with poor quality will cause broken bridge aluminum doors and windows rough and dull surface. After using for a period of time, discoloration or fading will occur. To a large extent, this is because some black-hearted merchants use aluminum waste recycling to re-make aluminum rod, and then use the profile machine to pull into various profiles, and then process them into window frames. Look at the quality of the profile surface. The selection of broken bridge aluminum doors and windows profiles is very important. Preliminary judgment of the quality of the profile can be judged by observing the surface of the Broken Bridge aluminum doors and windows. Generally speaking, the profile is relatively good Broken Bridge aluminum doors and windows, its surface is smooth and textured, and the color sprayed on the surface is also uniform and natural, which gives people a very smooth feeling.
3. Look at hardware
When decorating, the use of hardware is the most important. Because the hardware of doors and windows is the easiest to be cheated. Therefore, many people do not know what the hardware of doors and windows contains and what is better. There are two methods for these hardware. One is to directly put forward requirements from Broken Bridge aluminum manufacturers and give certain funds, so that broken bridge aluminum manufacturers can help get genuine goods high-quality hardware; the second method is to find regular hardware manufacturers and directly purchase hardware from regular channels for production. The second is to choose the hardware brand, which is often ignored by many owners. Here we reiterate that door and window materials are very important, and hardware is more important at the same time, because a good door and window cannot be separated from high-quality hardware, we compare doors and windows to a car. Good aluminum is the frame material of this car. Hardware is the engine of the car. Without high-quality hardware as support, the service life of doors and windows will be greatly reduced, at present, broken bridge aluminum of the high-quality hardware brands in the market mainly use: German sgiria hardware, Noto, Haobo, Italian GIS, German grid house and so on. The domestic brand hardware is the most outstanding.
It is not recommended to choose Miscellaneous brand hardware given by the manufacturer or hardware with the same name as aluminum in the selection of hardware. Why do you say so? The hardware presented by the manufacturer is usually of average quality. It is OK to use it for three or five years, but it is very difficult to use it for more than two or ten years like the window, at the same time, manufacturers often claim that the gifts are not guaranteed, so it is better to purchase them carefully. The second is hardware with the same name as aluminum, for example, broken bridge aluminum is called Si MOU shield, and hardware is also called Si MOU shield, that means that this hardware is a customized product of hardware that manufacturers find themselves, and its market price is 70-90 yuan per set, but some manufacturers sell consumers up to 300-400 yuan per set.
4. Look at the materials of the profile. High-quality Broken Bridge aluminum doors and windows, the thickness of the profile used is in line with the relevant national standards. According to the relevant regulations, the wall thickness of the window structure should be more than 1.4mm, the wall thickness of the door structure should be above 2.0mm. Look at the section. The quality is broken bridge aluminum doors and windows, and the geometric angle of the section is accurate. Accurate geometric angle cutting surface, so that it will not happen the phenomenon of bending and twisting, but the quality is poor broken bridge aluminum doors and windows, the cutting surface is not so regular, because the aluminum material is relatively small, its section is also very rough.
5. Look at the heat insulation strip of the profile. In terms of performance, the insulation strip of nylon is better than that of PVC. Nylon heat insulation strip has better high temperature resistance and low temperature resistance, and better heat insulation performance. Broken Bridge aluminum doors and windows with good quality, most of the profiles used are imported heat insulation strips. Moreover, it is the heat insulation strip. There is not much to say about the choice of heat insulation strip here, because the big brands of aluminum are all PA66 nylon heat insulation strips, and consumers of poor quality PVC heat insulation strips and high quality PA66 nylon strips will not distinguish, therefore, it is always right to choose broken bridge aluminum materials of the brand.
6. Choose high-quality glass
There are many kinds of glass, some of which are hard and some of which are soft. If you want to choose the glass of doors and windows, you must choose hard glass. This kind of hard glass must also be hollow glass, and the standard thickness of regular hollow glass is 5mm. Between the two pieces of glass and the glass will join nearly aluminum strip, so the thickness of the whole glass will be about 10mm to 15mm. The specific situation should be made and set according to the model and specification of doors and windows. Hollow glass in Broken Bridge aluminum doors and windows is usually tempered every 1.5 square meters, so the reliability of broken bridge aluminum doors and windows is very high.
