Security door is not anti-theft structure support frame is actually made of cardboard

    The lock market is too messy! With regard to security doors and unlocking problems frequently exposed, for our average consumer, how to distinguish between them is not easy. To this end, Xiao Bian also talked about some of the focus events on the market today, allowing you to see their true face, hoping to provide an effective reference for your life judgments.

    One of the focus events: In recent days, the Jiangxi Provincial Bureau of Quality and Technical Supervision found that in order to reduce costs, some manufacturing companies use very thin steel plate materials to produce and the quality of their products is worrying. After all, it is the technical supervision department, and if you say it, you have science and technology content. They explained this in detail: The cost of a metal sheet for a door is close to 500 yuan. There are more than 100 yuan for locks, painting for fillers, and the cost for polishing is 10 yuan. Workers' wages are 40 yuan. In addition to management, transportation and other expenses, the price of a security door that has reached the national standard is about 700 yuan. In addition, qualified anti-theft door single door weight should be more than 40 kg. All anti-theft doors below this price and weight should be purchased with caution.

    Xiao Bian Comments: Everyone is squeaking the saying, "Cheap is not good," but many consumers still unconsciously follow the tradition of "cheap, affordable" when they buy things. Especially in the hearts of consumers with weaker purchasing power, price is always the first factor. But we have to master a standard: Even if it is a processed product, there is a quality standard. In particular, some products related to safety must not be careless. Therefore, the "cheap-first" guiding ideology for the morning market to buy radish is OK, but if you continue to use large items, it may cause trouble for yourself and your family. How can it be "cheap" at the crucial moment?
