The need to protect your home has existed since time immemorial. Historically, people saw iron as something so hard and durable that they could protect themselves. Throughout the history of mankind, the technologies for manufacturing door structures, as well as the materials from which they were made, have changed many times. We will talk about such ordinary entrance metal doors, but as it turned out with a huge number of interesting facts and non-standard history. 
Fun Fact #1: In 2010, in Zurich (Switzerland), archaeologists discovered an entrance door that is about 5,000 years old. Thus, this find is the same age as the British Stonehenge. According to scientists, the door structure has survived to this day due to the fact that at that time the harsh climatic conditions forced people to build their houses around the lakes, and this required strong wood. 
Interesting fact #2: the oldest wooden door, still in operation, is located in Westminster Abbey (UK). It is reliably established that it is made of oak, cut down in the 11th century. Thus, the approximate age of the door structure is about 10 centuries. 
Interesting fact #3: all over the world, metal entrance doors are divided into 13 security classes. And if doors of 6-7 security classes are found everywhere in bank vaults, then the door steel system Security class 13 is only in Fort Knox (USA). Fort Knox is the repository of US gold reserves. The steel product, which reliably guards the gold reserves of the United States of America, weighs 22 tons and has a thickness of 1 meter. It is made of seven layers of steel, and was cooked using a secret technology. 
Interesting fact number 4: the tallest door in the world is located in the spacecraft workshop in Florida (USA). It has a height of 140 meters, and 45 minutes is the approximate time of its closing / opening. 
Interesting fact number 5: the heaviest door system is rightfully considered metal structure installed at the Lawrence Laboratory in California. Its weight is about 320 tons, and its thickness is almost 2.5 meters. And although it seems that with such a mass only remote opening / closing is possible, but thanks to special door hinges the system is also opened manually.
Interesting fact number 6: the fastest closing door products are installed in laboratories that work with explosives. In case of danger, they close in 0.3 seconds. Such a high speed is provided by nitrogen compressed to 1000 atmospheres.
Finding a reliable front door can be tricky, as the dilemma often comes down to price versus quality. From right choice construction depends on the safety of not only property, but also the owners of the premises.
First, you need to decide on the material of the door. AT modern world wood will not provide adequate protection, so there is only one choice - metal. Finishing is a matter of taste, but do not forget that the door will become a kind of "calling card" of the home. Examine the photo of the entrance doors, so as not to miscalculate with the appearance.
Secondly, good door will provide sound and heat insulation, which is especially important in northern latitudes.
Entrance door design
When selecting safety features, you can focus on the principle “the more the better”, but this can lead to an unjustified increase in the price and weight of the structure. Also pay attention to the ratings of entrance door manufacturers in your price segment.
The door frame is made in one piece, including a threshold, or U-shaped without it. Thresholdless design provides a lower level of security and is used in economy class doors.
The metal part made of cold-rolled steel is more expensive than hot-rolled steel, but of higher quality: the design is durable, light and strong.
The door from a steel corner is the most a budget option, however, is easily deformed. In a private house or entrance without an intercom, this option is the last thing you should look at.
A square profile with installed stiffeners and a steel sheet of at least 2 mm will provide higher strength. This design can be installed in a private house.
The door leaf must be made of steel sheet with a thickness of more than 1.8 mm. Purchasing a door that is too thin is not in your interest, no matter how tempting the price may seem: opening it is easy.
A high-quality door necessarily has vertical and horizontal stiffeners. A heater is placed between them. The more ribs, the better, but this will affect the weight of the structure. They must be evenly distributed to ensure proper reliability.
loops
The choice is between overhead hinges mounted on the outside, and internal ones installed inside the frame.
The first type must necessarily provide for anti-removable crossbars that prevent the removal of the door even with cut hinges.
Hidden hinges cannot be cut or unscrewed and are not visible from the outside. Unfortunately, there is a chance of a wedge, and then even the owner of the apartment will not be able to get home.
Hinges of heavy, massive doors should have support bearings to facilitate opening and closing.
Locks
The use of two locks at once will significantly increase the reliability different design: lever and cylinder. One of the advantages of the approach is that in the event of a breakdown of one lock, you can temporarily use another. If possible, install a custom-made lock.
When installing the front door, make sure that the lever lock of the “crab” design is correctly mounted - otherwise it may jam.
The cylinder lock should be additionally reinforced with an armor plate. If the design implies a latch from the inside, this is another layer of protection.
An important point: the locks should not be closer than 25 cm to each other in order to minimize the chances of cutting them out with a grinder at the same time.
Seals
Perform heat and sound insulation, as well as protection from odors. Doors equipped with seals fit more tightly to the porch and close more quietly.
Rubber is not without reason considered best material: it is durable, hardy, endures various influences. If necessary, the seal can be easily replaced with another one. Fixation takes place on the adhesive strip.
Some magnetic seals are too strong, which can make it difficult to open the door.
AT apartment building one layer is enough, in private, at least two are needed to protect against the cold.
Heaters
Commonly used foam, polyurethane foam and mineral wool. It should fit snugly against the stiffeners and the frame. cavities metal profiles are also insulated.
In a private house, polyurethane foam will better cope with the role of insulation, in an apartment - basalt wool. Styrofoam is commonly used in alliance with mounting foam, which fills the resulting gaps.
Price segment
Of course, not everyone can afford an option that fully meets all requirements. We offer you to figure out how to choose the front door in different price categories.
Economy
Budget models are usually made in China, but there are also from domestic manufacturer. The price varies between 7-10 thousand rubles.
The design provides for one sheet of steel up to 1 mm thick with a thickness door leaf 6-7 cm. Stiffeners do not include additional reinforcements. Finishing is made of MDF or plywood. They can provide attractive appearance, but the safety of such a door is rather questionable.
Average
The price can be 10-20 thousand rubles. Along with the cost, the quality of the construction also increases. The door of the middle segment performs a better protective function.
Includes 2 sheets of steel with a thickness of more than a millimeter, the sheet itself is more than 8 cm. There are additional seals and thermal insulation. Locks are equipped with protection against opening. You can choose from a variety of finishes more options.
Upper
The next price segment includes doors costing from 20 to 30 thousand. They provide maximum safety and reliability. They can be called the best entrance doors to the apartment.
Locks on the door receive enhanced protection, there are anti-removable hinges and additional stiffeners. With a web thickness of 8-10 cm, use steel sheets up to 2 mm. Be sure to have good sound and heat insulation.
Elite
This category includes doors more expensive than 30,000 and made according to custom order. Their main difference from the doors of the upper segment is a higher quality finish made of natural wood or stone, the presence of forging.
This also includes armored doors, the thickness of steel in which can reach 5 mm. They will withstand even a strong blow.
Some models have the ability to control using the remote control.
