PREMA B-434, model 172

Door leaf

The door leaf has a reinforced structure with 4 stiffening ribs and additional metal pockets for the lock. The leaf thickness is 72 mm, the metal profile thickness in the leaf is 1.2 mm, and the steel sheet is 0.5 mm. This provides the door's strength and stability and increases its resistance to external impact. The frame and leaf are powder-coated, which gives the door a long service life and protects it from rust.

Anti-removal bolts

The door has three anti-burglary bolts 14 mm in diameter; they are also called anti-removal bolts. They protect the home from intruders. If the door hinges are cut off with an angle grinder, these bolts keep the door locked in the frame.

Door insulation

The door leaf is insulated with mineral wool, which helps keep the room warm and prevents cold air from entering. The door frame is not insulated. The door is also fitted with two euro-seal contours that provide effective thermal and sound insulation in the apartment.

Door frame

The door frame is made of a bent profile of cold-rolled steel 85 mm wide. The metal sheet thickness in the frame is 1.2 mm, which guarantees the longevity and reliability of the structure. The openings for the lock bolts are reinforced with an additional metal sheet, which raises the security level.

Locks

The door is fitted with the following locks:

Top safe-type lock Class 88D. Bolt diameter - 14 mm, throw - 34 mm.

And the bottom lock Class 252 with a 30×40 cylinder mechanism, key / thumbturn. Three bolts of 14 mm diameter, throw - 34 mm.

Hardware

The door hardware is square-shaped, in black shagreen, giving the door elegance and style. The door comes with a Smart-A-type handle on a rose.

Pressure regulator

The door has a Securemme (Italy) pressure regulator that adjusts how tightly the leaf presses against the frame and ensures a smooth closing. Thanks to the maximum pressure of the leaf against the frame and the sealing contours, your home is protected from noise and unpleasant smells from the stairwell.

Concealed-mounting trim

An exterior MDF trim 80 mm wide will give your door a finished look and aesthetic appeal.

Door size

The door has two standard size options: 840×2040 mm and 940×2040 mm.

Door weight

Depending on the size, the door weighs 62 kg or 70 kg. This confirms its strength and reliability, while three hinges keep the door from sagging and ensure a smooth swing.
