The quality of plastic steel doors and windows is shoddy and the installation is rough, which leads to the continuous increase in the quality of plastic steel doors and windows. At present, the inferior quality of doors and windows, which are randomly assembled, have problems such as large price gaps, large amounts of water, and irregular installation. How do consumers choose plastic steel doors and windows products and services?
Merchant shoddy
In terms of product quality, merchants mainly use three methods to shoddy the following: First, the use of small profiles, originally used to make doors and windows or indoor partitions, some dealers used to encapsulate balconies for consumers Because the strength is not enough, it is easy to have quality problems; the second is the use of unqualified plastic steel profiles, which will have problems such as deformation, cracking, slag and discoloration during use; third, no steel lining or The thinned iron sheet is impersonated as a steel lining, and the assembly does not guarantee the overall quality of the doors and windows. In the installation of plastic steel doors and windows, the problems caused by the irregular operation of the construction team abound. This kind of problem is mainly caused by the inattention of the installer during handling, loading and unloading, and installation.
Plastic steel doors and windows installation precautions
Therefore, the installer should handle it gently during installation, and must not smash, smash or fall. Knock on the door frame and gently knock it with a plastic hammer. Do not use a hammer to knock. Secondly, after the installation of the doors and windows, the phenomenon of tilting and poor sliding of the door leaf is caused. This is mainly because the installer does not use the line pendant and the ruler to check the verticality of the door and window and the ground or the table during the installation process, resulting in excessive deviation. Therefore, when installing doors and windows, be sure to follow the installation specifications. Doors and windows are not level. After the door and window are installed, there is a problem that the height of one head is low, the gap between the fan and the frame is uneven, and sometimes there is a problem that the upper width is narrower or the lower width is narrower.
The sequelae of free installation fees When purchasing doors and windows, consumers should not blindly pursue the material texture, but ignore the technical requirements and weight of processing, installation and service. Plastic steel windows, broken bridge insulation aluminum alloy, pure wood windows are energy-saving profiles, but the products produced by different manufacturers vary greatly. Consumers choose doors and windows only to compare material texture, which will lead to insufficient investment in installation and service.
In order to attract customers, some manufacturers have flagged the installation fee. The door and window industry has a "three-point production, seven-point installation", and the quality of doors and windows is more caused by the installation. Free installation fee, this is actually a trap, a problem, the manufacturer can say that this is an installation problem, I will not be responsible for the confiscation of your installation fee. Therefore, as a consumer, not only does not emphasize the installation fee, but also clearly install materials and install labor costs in the contract.
Inspect the "Yan" view "color" to distinguish between good and bad
The appearance color of plastic steel doors and windows should be blue-white, the color is too white or gray, indicating that the stable composition in the material is not enough, it will be aging and yellowing for a long time; the surface should be smooth and flat, without open welding; the door and window frame and the fan profile should be embedded. There is a special steel lining. The sealing strip should be flat, no curling, no grooving, and the strip is odorless. The hardware is flexible and smooth; the auxiliary materials such as the bead and seal of the plastic steel doors and windows should be matched with the main profile; the drainage trough and the air pressure balance hole are processed in a staggered position to avoid the direct entry of cold air and dust, and the tightly packed plastic steel window drainage hole part is assembled. They are equipped with a closed cover to prevent rainwater from flowing into the room from the hole; the glass used for plastic steel doors and windows should be flat, water-free, and firmly installed. It is not in direct contact with the plastic profile, and there is a sealing bead to close the gap. If it is a double glass interlayer, there should be no dust and water vapor in the interlayer; the lower part of the sliding window frame should have an aluminum sliding rail to facilitate its replacement. In general, the double pulley is superior to the single pulley.
The price is less than 200 yuan. Do not buy plastic steel window pricing method and other decoration materials are the same, are calculated in square meters, including the cost of screen windows. In the three plastic steel windows of swinging, hanging and pushing, the price of the sliding window is the lowest, the small assembly plant is about 160 yuan per square meter, and the imported product is 600 yuan per square meter. The price of the casement window 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, an additional 30 yuan for the delivery fee and a window fee of about 50 yuan will be added.
The technical content of plastic-steel windows varies greatly. The processing equipment of roadside stalls is simple, the precision and strength of doors and windows cannot be guaranteed at all, and the quality of profiled steel is inferior, even without lining steel, other accessories are also very poor. According to reports, under normal circumstances, the price of the sliding window is less than 200 yuan, and the casement window is lower than 300 yuan, it is very likely to use fake conch, Shide profiles, or through the use of inferior, low-cost hardware, steel lining When assembling components to reduce costs, consumers should be careful to buy.
Consumers can obtain the test report of plastic steel materials from the seller before selecting a certain brand of plastic steel doors and windows, and check the four main indicators, namely hardness, low temperature drop impact test, high and low temperature dimensional change rate and angular strength test. Meet the requirements.
