Is it necessary to thicken the security door?

It depends on which one you are more interested in and which one is more useful.

You should take a look at the quality of the security door, and if it's too bad, it's better to replace it.

Some communities can not be replaced, but it is not a big problem to coordinate with the property, the fire door is not anti-theft, and the safety factor is relatively low. But if you want to change, be sure to inquire about your property within seven days, many users buy the door, and when the installation time is delivered, the door is sent to the community, and the property is not allowed to enter, which is also very troublesome.
