According to the person in charge of the Quality Inspection Center of Building Decoration Materials of the Municipal Institute of Quality Inspection, plastic-steel windows are products that the country has compulsorily managed in the form of production licenses. Without production licenses, it is forbidden to produce plastic-steel windows for construction (that is, the plastic steel windows of citizens' homes). . Kazakhstan has more than 1,000 listed plastic windows, and only about 150 have production licenses, and the rest are “workshop†type production. Because these "workshops" are generally set up in residential areas, most of the plastic windows for public exchange are produced and processed by these "workshops."
Citizen Liu, in the process of installing the plastic window, the sash's actuator was out of order, the factory was unloaded, and it was taken back for repairs. Liu looked forward, looking through the screw hole and found no lining in the window sash.
A few days ago, it rained a strong wind, and Lee lived on the 12th floor and the newly-changed balcony-plastic window was blown straight. The on-site inspection by the quality inspection department found that the lower crossbeam of the plastic window had no steel lining, and only 6 of the 6 standing uprights had steel liners, and the thickness of the steel liner was not enough.
It is understood that the public complained that the most problem with plastic-steel windows is that the thickness of the steel lining is unqualified or that there is no steel lining; followed by a failure of the transmission angle chain, aging of the sealing tape, cracking and even cracking on one pull, and the use of “workshopsâ€. The “second-hand goods†removed from other plastic steel windows are re-processed into windows, and then installed for the citizens... “Workshop†has problems in the processing technology of the plastic steel window factory itself, together with cutting corners, shoddy methods, etc. Caused by the public to change the plastic windows of the ventilation, water seepage, no resistance to wind and other quality problems.
The quality inspection department reminded the public that to change the plastic windows to look for manufacturers with production licenses, it is necessary to understand in advance some of the quality standards of plastic windows and check them against the standards.
Right now, it is during the decoration season that more people are changing plastic steel windows. The number of complaints against plastic windows has also increased. The plastic steel window complaints received by the Consumers Association and the quality inspection department have ranked first in all kinds of home decoration materials.
