What parts make up a door?

Each door is made up of three essential parts directly related to the security it offers:


1. Frame. Intruders attack this part by prying it out of the wall with a bar. The strongest frames are those made of steel or aluminum , followed by those made of solid wood . The least resistant are those made of MDF.


2. Internal structure . The door leaf is another point susceptible to being forced. The most resistant are those of the armored security doors , with an internal structure of reinforced steel profiles , followed by those of sheet metal and polyurethane foam . Solid wood and wood reinforced with sheet steel have less resistance.


3. Closure system . About 87% of attacks on front doors are made by forcing the closing system . It is essential that the door has:


Specific and quality locking system to prevent attacks with picks, drills or other tools.Keys with controlled copying , or patent-protected non- copyable keys.Locking points (groups of bolts), a cylinder or security cylinder that activates the lock and forces the use of a security key to turn the bolts. A cylinder security shield that protects it from violent attacks and access to the internal mechanism of the lock. The more resistant the cylinder and escutcheon are, the more protected the lock drive system is.


Within these closure systems , these are the key components:


Lock: it can be standard, security and high security. It is what gives movement to the closing points. Closing points: group of bolts. The more there are (5 is the maximum, 3 the medium and 1 the minimum), the more security the door offers. Bolts: metal pieces that come out of the door and block its movement when joining the door and frame. Cylinder: better known as a bowler hat , it is the part where we insert the key and the one that activates the locking points by means of the key and protects the lock. There are standard, security and high security. Shield:protects cylinder and lock. Its function is to prevent the door from opening or breaking the cylinder with pliers. They can be simple or security shields (flared) -which are the ones with armored doors-. Keys: the most secure are patent-protected non-copyable keys. Only the owner of the door would have access to make copies of the key.
