Often time we hear the saying: “My house is my fortress”.
The person feels very safe when he knows that he has strong and secure door.

Look at door models
  • Construction

    In door production we use the most advanced bending — profiling technology. It makes it possible for us to produce door with high preciseness.

  • Security

    High level of security is achieved by multilevel protection system of the metal door that prevents unsanctioned burglary attempts.

  • Heat and sound insulation

    German sealing system called “Hoffen” and eco-friendly insulation are able to block the noise and guarantee high level of insulation.

  • Durability

    High quality steel and anti-corrosion treatment; world known door furniture producers and resistant coating makes our doors durable and long lasting.

Construction of the Door

Wholesome bended door sheet

Wholesomely bended sheet of steel of optimal thickness functions both as a frame and as external shield of the door. Absence of welding stiches makes it impossible to bend the steel at the point of welding and thus prevents access to the door's locks.

Hinges

Door hinges are specially designed and produced in Italy. The tests have proven that hinges can bare at least 300 000 open & close cycles.

System of Stiffeners

Vertical and horizontal stiffeners produce maximum strength for the door. The system is highly resistant to torsional loads and attempts to bend the door to get to the locks.

Reinforcing steel plate

External side of the lock is protected by the steel plate, which protects the lock from drilling and increases durability of the door against burglary. The thickness of the steel in the lock area is 3 mm.

Irremovable crossbars

Irremovable crossbars tightly fit into the openings in the door box, which makes it impossible to take the door off the hinges. Being 14 mm in diameter, the crossbars are not noticeable and do not spoil the aesthetic looks of the door.

Ecological Insulation ISOVER

Mineral wool ISOVER has high insulating properties. Ecology friendly insulation has 100 mm thickness and put into the door and door box in double layers.

Controller

Controller (eccentric) allows adjusting the tightness with which the door stays to the door box. Correct tightness does not let the cold air and odors come through the cracks into a house.

Sealing contours

German made Höffen door sealing system ensures silent closing of the door and provide additional heat and sound insulation. When noise outside is 75 dB, the noise level in the room does not exceed 35 dB.

Locks

Steel Line company installs locks from different manufacturers that correspond to the 3rd and 4th level of security. All door furniture is made either in Italy, Turkey or Israel.

Security

All entrance doors made by Steel Line company have the 5th (highest) level of anti-burglary protection. Such level of security is achieved by multilayered security system that is especially designed by factory’s constructors.

Wholesomely bended sheet of steel of optimal thickness makes it impossible to bend the steel at the point of welding and thus access the door locks. The door locks are well protected from outside and inside.

In special lab we test the door and how much weight/force it can take. After the tests the Steel Line doors has proven to take applied force of 1000 Н (weight of 1000 kilograms).

Reliable Locking System

Locks of different types

The Steel Line Company installs lever and cylinder locks made by world renown manufacturers. Using different types of locks significantly increases the door resistance to cracking.

European cylinders

All the lock has euro cylinders with possibility to change the code on the key.

Reinforcing steel plate

External side of the lock is protected by the steel plate, which protects the lock from drilling and increases durability of the door against burglary. The thickness of the steel in the lock area is 3 mm.

Armored Patch

In order to protect cylinder locks, we install the armored patch made from hardened steel and have high degree of security against burglary.

Heat and Sound Insulation

German System Höffen

Sealing the door using German sealing system allows to retain heat 10 times better than usual. Additional insulation in the door boxes installed in the factory and correct insulation of door slopes significantly reduces sound and heat transfer coefficient.

Insulation “KNAUF”

Two layers of environmentally friendly insulation within the door and door boxes is installed as whole sheet. The special technology of fixing the insulation on the entire height of the web allows insulation to stay in place the entire life cicle of the door.

Door Panels

Material used on exterior of the doors is made of wood and has high insulating properties. Because of its density and structure, the door panels are perfectly quenching the sound waves and vibrations.

The durability of the front entrance door

Metal Processing

The durability of the entrance doors is ensured by the quality of steel and anti-corrosion treatment. The new technology protects the surface with phosphating coating against corrosion and ensures durability of the coating.

Controller

Door box has a controller that adjusts the tightness with which the door adjoins the door box. Correct tightness does not let the cold air and odors come through the cracks into a house. It also ensures smooth working of the locks and comfortable clothing of the door.

Italian Hinges
Reliable coating

Persistent anti-vandal Vinorit cover is suitable for outdoor usage: it does not fade, resistant to temperature changes and mechanical damage. For models with doors painted MDF panels the company uses weatherproof, high-strength Italian paints and varnishes.

Door Furniture

We test and check hardware durability and wear resistance of the door by installing the door in areas with a large flow of people. The locking systems are tested for trouble-free opening at different deformations.

Controller

Door box has a controller that adjusts the tightness with which the door clothes to the door box throughout the service life of the door. It also ensures smooth working of the locks.
