Hello, the stainless steel iron door is still quite good, but pay attention to check whether it is a renovated old door, you can pay attention to the turnkey process. Under normal circumstances, the packaging of the new security door is intact, the installer packs it in front of the customer, the key should be in the package, the packaging of the key should also be complete, the lock cylinder should be installed in front of the customer, and then the key is handed over to the customer after the lock is installed.

The difference between the anti-theft door and the stainless steel door should be that the anti-theft door has the function of anti-theft, and the anti-theft door can also be a stainless steel door, but the stainless steel door is not necessarily an anti-theft door, he may be a simple stainless steel door. I think it has nothing to do with the material, it has to do with the function.
