Anonymous users2024-01-22Zhejiang Zhongheng anti-theft door is the most garbage door. Zhongheng anti-theft door is the most garbage door, I sell anti-theft doors, before looking for them Fujian agent warehouse took a few doors, are different degrees of quality problems, I find them to solve, they find a thousand reasons, a thousand words to refuse after-sales, really have nothing to say when actually said that the customer deliberately hangs difficult, the customer has nothing to do. Later, I bought the accessories myself and asked a professional locksmith to pay for it, which cost some money.
Fortunately, I'm more knowledgeable. If it's an ordinary buyer, it's enough for you to have a headache.

Normally, the anti-theft doors are sandwiched in the middle, and the sound insulation effect will not be bad, which can meet the requirements of family use. In addition, the structural features and sealing of the security door can also affect the sound insulation, such as the design of the U-shaped notch to make the door and door frame more tightly bonded.
