If the level is the same, the heavier the safer if the level is the same, the larger the weight, the more lock points, the denser the steel skeleton, and the more locks protect the anti-theft door, the quality is relatively good.

Since it is difficult to see the skeleton of the security door, the owner can refer to the product section (section) provided by the dealer and judge it from the weight. Generally speaking, the greater the weight and the denser the steel skeleton inside, the stronger and safer the door.
