Protection from burglary

Front door is one of the options for unauthorized entry into the house. Reliable protection from burglars is important for both apartment and private house owners. There are two major ways for thieves to break open the door: intellectual and forceful.

Защита двери от взлома

Protection from intellectual hacking

Intellectual hacking assumes manipulative actions directed to the locks or other door furniture. Anti-burglary effectiveness of the lock depends on the type of the lock, its safety class and other protective features.

Type of hacking

Drilling of
the guiding pin

If the burglar knows the type of
locks installed in the door, he can
detect the location of the guiding
pin, drill a hole in it and destroy
the guiding shank.

Protection methods

Thickness of the door panel and the steel plate in the lock’s area greatly increases the drilling time and makes the borer break.

Guiding pin used in the doors manufactured
by Steel Line is made of tampered steel and
has the highest capacity to withstand drilling.

Type of hacking

Breaking the
guiding shank
by wringing

By applying powerful device it is
possible to push on ledges on the
guiding shank of the lock. After the push,
this device turns sharply, thus breaking
the guiding shank and giving the entrance
of the thief into the house.

Protection methods

By providing specially designed ledges we trick the criminal. The powerful push and turn device will break the false ledges without destroying the guiding shank.

The thickness of the metal used in Steel Line doors does not allow the wringing device to reach door’s guiding shank.

Special steel plate increases the thickness of the metal in the area of the locks.

Type of hacking

Opening the lever
lock by using
two picklocks

Hooklike picklocks are used in
order to move the latch and raise
the lever, which helps to open
the lock easily and silently.

Protective
pad

Защита от интеллектуального взлома

Protection methods

False gutters on levers and special jags
on the guiding shank make it impossible
to pick the right code.

Protective pad hides the keyhole on the door and makes it much harder to gain access to the gutters on the lever.

Защита от интеллектуального взлома

Type of hacking

Opening
cylinder locks
with picklocks

This method is directed to the latch
itself: the locking mechanism is thoroughly analyzed and then the secret elements are picked in the right order. Such correct order will get the lock to open.

Protection method

Small opening of the cylinder keyhole and special catchers with steel pins makes it very difficult to place elements in the precise order. Thus, it is impossible to pick correct combination.

Type of hacking

Wringing
the cylinder

Wringing tool is placed in the widened
keyhole of the cylinder lock, and then
it is twisted with the key, which breaks
the secret elements.

Protection method

Pins the cylinder’s body are made of extra durable steel that greatly improves the strength of the lock. Pins and central part of the cylinder are reinforced with steel inserts.

Type of hacking

Picking the right key
to unlock the lock

Small number of code combinations
increases the chance of opening
the door by finding the right key.

Защита от интеллектуального взлома

Steel Line only uses the locks with the highest protection certificates, some of the locks have over 10 million secret combinations of the cylinder.

Защита от интеллектуального взлома

It is also possible to re-code the lock: main key cancel the key set used during construction or remodeling.

Type of hacking

Knocking and
drilling the cylinder
of the lock

Cylinder can be knocked in or
broken out. The central part can
be drilled with electric drill.

Protection methods

Moving armored pad will move in the same direction as the drill borer, making it impossible to drill through it.

The base of the armored pad is made of soft steel. Therefore, when tools are applied on it, the sides of the pad will bend and it becomes impossible to catch the armored pad.

Защита от интеллектуального взлома

Design of armored pad makes it impossible to catch it with the pincers.

Protection from forceful hacking

Forceful hacking of the door assumes at least partial breaking of the door itself of the door locks. Applying physical force is the essence of such hacking.

Защита от силового взлома

Type of hacking

Mechanical pull-up
of the door panel

Pry or crowbar is placed between the door box and the door panel somewhere near the locking area. The door is being pulled until locking pins are forced out of the lock.

Protection methods

The length of the locking pins also contributes to the anti-hacking capabilities: the longer the pins the more time it will take for the burglar to pull it out of the lock.

Door box made of wholesomely bended profile makes it possible to sink the door panel into the door box. Location of the door in the same plane as the door box increases its capacity to withstand the crowbar’s force.

Type of hacking

Breaking off the steel sheet
from the door’s angle

At the welding points it is quite possible to tear off the steel sheet from the door.

Protection methods

Bending-profiling technology makes it possible to build the door from wholesomely bended sheet of steel. Since there are no welding stitches, it is impossible to tear off the steel sheet at welding points.

Type of hacking

Cutting the
door panel

Outer steel sheet of the front door panel is cut in the locking area by using special metal cutting scissors. When the access to the door lock is achieved, then the lock gets broken or the latch gets removed.

Protection methods

The thickness of the cold-rolled steel can be up to 1,5 mm, which guarantees high level of resistance to forceful hacking.

Steel plates installed in the locking area make it much more difficult to cut through it and much harder to drill to saw it off.

Combined with reinforced stiffeners the protective system resists wringing and forceful hacking.

Защита от силового взлома

Steel Line installation specialists individually approach every customer and his door way when it comes to door installation.

Type of hacking

Cutting off door hinges

It is possible to cut off door hinges by using special cutting equipment. In this case the door gets open on the side opposite to the door locks.

Защита от силового взлома

Protection methods

Two irremovable crossbars make it almost impossible to open the door by cutting off its hinges.

Type of hacking

Knocking out the door
together with the door box

The door and the door box can be forced inward by applying mechanical equipment.

Protection methods

Fastening the door through the door box by using steel anchors fully prevents the inward forcing of the front door.
