this test frustrated Mr. Ni. The aluminum alloy windows installed at the beginning actually had no quality at all. However, he is more depressed that it is difficult to find reliable aluminum alloy stores. The temporary store is afraid to find. Looking at the better store, there is no contract. Different stores have different opinions and have no choice

in the survey, it is not easy for citizens to find a reliable aluminum alloy door and window store. According to the regulations, aluminum alloy doors and windows of projects such as real estate projects need to be tested by professional technical testing departments before they can be installed and used, and the quality is reliable. However, the aluminum alloy doors and windows that citizens find themselves do not have these requirements. Some so-called brand aluminum materials may also be fake. It is clearly marked with the compulsory certification mark of 3C tempered glass, but it is fake. Consumers simply cannot identify it. The quality depends on chance

in the interview, an insider who operates aluminum alloy windows revealed to the reporter that many aluminum alloy door and window stores are guerrilla. As long as a building is delivered, many aluminum alloy door and window stores will appear nearby in an instant. It is convenient for residents in the community to plan. If you want to pack a balcony or sunshine room, you will find these stores. Two years later, these small shops will move out and re select the newly delivered community for temporary "camping". If there is a quality problem with the doors and windows installed by citizens, it is difficult to find them
