After the delivery of the new building, some owners will seal the balcony or make it into a sunshine room. Mr. Ni, who lives in Jindi International Garden, also sealed Nanyang terrace with aluminum alloy glass windows. However, what he didn't expect was the installation of aluminum alloy doors and windows around the new building www.yidunmc After the delivery of the new building, some owners will seal the balcony or make it into a sunshine room. Mr. Ni, who lives in Jindi International Garden, also sealed Nanyang terrace with aluminum alloy glass windows. However, unexpectedly, a thunderstorm and strong wind at the end of August blew his aluminum alloy glass windows askew, and the glass fell to the ground. In order to reinstall, Mr. Ni began to look for a new aluminum alloy store. Different stores have different opinions, have no choice, and are unable to provide contracts, which makes Mr. Ni more depressed

Mr. Ni's house was delivered in 2008. There is a balcony 2.7m × 8m wide in the south. After moving in in 2009, with the consent of the community property, they plan to wrap the balcony in the South with aluminum alloy windows

Mr. Ni found an aluminum alloy door and window store in the south of the community. At that time, the owner of the store promised that the windows should be made of double-layer tempered glass, and the aluminum alloy should also be made of high-quality materials to ensure that there is no water leakage in the rain. However, one year later, the aluminum alloy doors and windows began to seep, and the windows would shake when encountering strong winds

in the evening of August 27 this year, thunderstorms and gales occurred. The aluminum alloy window of Mr. Ni's house was blown out: after the door and window were deformed and squeezed, the glass was broken and scattered on the ground. Many glass fragments had sharp corners, and some fragments kept falling downstairs. During the inspection, Mr. Ni's hand was also scratched by the glass

then, Mr. Ni took his broken aluminum alloy and glass to Yinzhou District product quality supervision and Inspection Institute. The Engineer wangyaodong looked at the glass sample provided by Mr. Ni and said without thinking, "this is not tempered glass, it is fake. There is a black line in the middle of the tempered glass, and it is broken into small particles, which is not easy to scratch the skin."

Wang Gong measured the thickness of aluminum alloy with a vernier caliper and found that its thickness (excluding powder spray) was only 1.2mm. According to the national standard for aluminum alloy external windows, the thickness of aluminum alloy external windows should not be less than 1.4mm

Wang Gong also found that the glue used to bond aluminum alloy and glass is also very greasy. A piece of residual glue on the aluminum alloy material provided by Mr. Ni, gently pulled, immediately broke and was inelastic. "After 5 years of use, the glue is like this. A good adhesive can be used for more than 30 years."

in addition, Wang Gong also found that the aluminum alloy window provided by Mr. Ni lacks one key thing, namely, the pressing line. Only by bonding it with the glass can it play a good role in fixing and waterproof
