The quality of plastic doors and windows shoddy, rough installation, resulting in the continuous increase in the quality of steel doors and windows. At present, arbitrarily assembled inferior doors and windows under the guise of profile brands, there is a big gap between the price of the same brand, more water, and irregular installation. How do consumers choose plastic steel doors and windows products and services?
Three methods are used to introduce qualified professionals. In terms of product quality, merchants mainly use three methods to shuffle products. First, they use trumpet profiles. Originally, such profiles were used to make doors and windows or interior partitions. Some distributors are used to package the balcony for consumers. Due to insufficient strength, quality problems are easily caused. Second, unqualified plastic steel profiles are used. Such plastic profiles will deform, crack, dregs, and discolor in use. The third problem is that steel lining or steel sheet is not used as steel liners in doors and windows. The assembly cannot guarantee the overall quality of doors and windows. In the installation of plastic steel doors and windows, the problems caused by the non-standard operation of construction teams abound. This kind of problem is mainly caused by the carelessness of the installer during handling, handling, and installation.
Therefore, the installation personnel should take care when installing, and do not smash, throw or fall. Beat the door frame and use a plastic hammer to gently knock. Do not use a hammer to knock. Secondly, after the doors and windows were installed, there was a phenomenon of incline and sliding of the door sash. This was mainly due to the fact that the installer did not use the wire cradle during the installation process to check the perpendicularity of the doors and windows to the ground or the countertop, resulting in excessive deviation. Therefore, when installing windows and doors, it must be done according to the installation specifications. The doors and windows are not horizontal. After the doors and windows are installed, there is a phenomenon of unevenness of the gap between the fan head and the frame, and there is sometimes a problem that the upper width is narrower or the lower width is narrower.
Excessive installation fees have sequelae. When purchasing doors and windows, consumers should not blindly pursue the texture of materials, and ignore the technical requirements and weight of processing, installation, and service. Plastic-steel windows, broken-bridge heat-insulating aluminum alloys, and pure wood windows are energy-saving profiles, but products produced by different manufacturers vary greatly. Consumers choose doors and windows only to compare the texture of materials, which will lead to insufficient investment in installation and service by manufacturers.
Some manufacturers use the banner of free installation fees to attract customers. The door and window industry has a "three-point production, seven-point installation," saying that the quality of doors and windows is more caused by the installation. Free installation fee, this is actually a trap, a problem, the manufacturers can say this is an installation problem, I confiscation of your installation fees can be irresponsible. Therefore, as consumers, not only does not emphasize the exemption from installation fees, but also in the contract to clear the installation of materials and installation of labor costs and other content.
Inspecting the "color" concept "color" to identify the appearance of plastic doors and windows should be green and white, pale or gray color, indicating that the stability of its ingredients in the material is not enough, easy to aging and yellowing; surface should be smooth and flat, no Open-welded fractures; special steel linings should be embedded in the window frames and fan profiles. The sealing strip should be flat, without curling, no grooves, and no odor. Hardware is flexible and smooth; auxiliary materials such as beading and sealing of plastic steel doors and windows should be matched with the main profile; drainage grooves and air pressure balance holes are processed in a staggered position to avoid direct entry of cold wind and dust, and a relatively rigid plastic steel window drain hole part is assembled. All are equipped with a closed lid to prevent rain from flowing into the room from the hole; the steel used for the steel doors and windows should be flat, free of grain, and securely attached. It should not be in direct contact with the plastic profiles, and the seal bead should be in close contact with the gap. In the case of a double glass sandwich, there should be no dust and water vapor in the sandwich; the sliding window should have aluminum slides in the lower part of the window frame to facilitate its replacement. In general, the double pulley is better than the single pulley.
The price is lower than 200 yuan do not buy plastic steel window pricing and other decoration materials are the same, are calculated in square meters, including the cost of screens. Among the three types of steel windows, which are flat-opening, hanging-hanging, and push-pull, the lowest price for sliding windows, 160 yuan per square meter for small assembly plants, and 600 yuan per square meter for imported products. And the price of Pingkai Chuangzhong is middle, the price is 250-1000 yuan per square meter; the price of the upper hanging window is the highest, about 300-1200 yuan per square meter. In addition, a delivery charge of 30 yuan and a window removal fee of 50 yuan will be added.
The technical content of plastic-steel windows varies greatly. The processing facilities for roadside stalls are simple, and the precision and strength of doors and windows cannot be guaranteed at all. Moreover, the quality of profile-lined steel is poor, and there is no lining steel, and other accessories are also poor. According to reports, under normal circumstances, the price of sliding window is lower than 200 yuan, and flat window is lower than 300 yuan. It is very likely to use false conch, Shide profiles, or through the use of inferior, low-cost hardware, steel liners. As components are assembled to reduce costs, consumers should purchase it with caution.
Before choosing a certain brand of plastic steel doors and windows, consumers can obtain a test report of plastic materials from the seller first, and check their four main indicators, namely whether the hardness, low temperature drop impact test, high and low temperature dimensional change rate and angular strength test are Meet the requirements.
