Miss Wang said that when the lock disappeared after several years of magnetism, a key could open the magnetic lock of the entire community. "You can open anything you want, as long as it is a piece, it can be opened like a key."

In another high-quality anti-theft store, Xiao Wei, a salesperson, told reporters that Wang Li ’s magnetic locks were indeed class B locks, but due to the current price drop in the market, their anti-theft doors “have not reached all (class B)” .

Fireproof rock wool door quality is more reliable

It is understood that the internal fillers of anti-theft doors currently mainly include polyurethane insulation materials, refractory rock wool (many merchants call it fire-resistant rock wool) and honeycomb paper. Among them, the quality of using refractory rock wool as a filler is better.

The anti-theft door filled with fireproof rock wool can integrate the door leaf with the inner cavity, and the anti-theft performance is better. In addition, the thermal insulation and sound insulation performance of the fireproof rock wool security door is also very good. In addition, many anti-theft door sales staff said that many anti-theft doors in Zhejiang use honeycomb paper, such as Wang Li and Bu Yang.

The person in the industry also suggested that when buying an anti-theft door, consumers unscrew the cat's eye, and the structure inside the anti-theft door can be seen.

In addition, the security door of the same thickness is filled with honeycomb paper, which is lighter in weight.

The reporter learned from the market that at present, the sales of honeycomb paper security doors in the market in Beijing are very poor.
