In accordance with the requirements of the national mandatory standard "Code for Fire Protection Design of Buildings", for buildings with a height greater than 54 meters, the exterior windows of one room of each household should use fire-resistant windows with fire resistance integrity of not less than 1 hour. If the fireproof glass installed is not up to standard, once a fire breaks out in a high-rise building, the consequences will be disastrous.
At the end of December 2023, reporters received reports from the masses: In some markets selling fire-resistant glass in Tianjin and Hebei, the quality of fire-resistant glass produced by individual companies did not meet standards. The reporters at the March 15th Gala visited a company in Tianjin that specializes in the production of fire-proof glass. However, on the production line, the reporter did not see the processes of spraying fire-proof liquid on the glass and drying it. After repeated questioning by reporters, a worker said that the fire-proof glass on the factory production line is actually ordinary tempered glass without any fire-proof treatment. "If people want to pretend to be fire-proof, they just need to put a label on it."
Not only fireproof glass manufacturers in Tianjin but also in Hebei are also engaging in the same fraud. Some staff even said that they can provide customers with corresponding qualified inspection reports. "My inspection report is (fire-resistant) for one and a half hours, but in fact my glass can only be (fire-resistant) for half an hour." Industry insiders revealed that the product It is the glass companies that go to the management department to submit them for inspection, so they prepare expensive qualified fire-proof glass, pretend to be their own products to submit for inspection, defraud the qualified inspection report, and then openly sell fake and shoddy products.
What is the difference in fire resistance between fake and shoddy fire-resistant glass and real fire-resistant glass? Staff from the National Consumer Protection Inspection Center found that fireproof glass samples produced by counterfeit companies deformed and cracked in less than 4 minutes at high temperatures.
