The upper part of the security door for the fence-type steel pipe or steel plate, the lower part of the cold-rolled steel plate, the use of multiple locking points to lock the security door to ensure the ability to prevent prying. But in the anti-theft effect is not as good as the closed security door.

When choosing a lock, look at the lock material.

2. Lock key

That is the purchase of security locks, the public can observe the key “teeth”, the more complex the arrangement, the more difficult it to open, the better the security performance.
