Metal door in the section

The price range of steel doors is quite wide. You can find models worth five thousand, or 10-15 times more expensive. What is the difference, and which design is right for you? It is worth taking a closer look at the technology of manufacturing entrance doors made of metal.Varieties of metal doors manufacturers offer customers models with one steel sheet, with two sheets of sheathing, or sheathing of the frame with steel on only one side. If the thickness of the sheet is more than two millimeters, then the reliability of the door increases. It is clear that a thin tin can be opened without much difficulty. Tin is generally suitable for making cans, and not for an entrance and a solid door.The ideal solution for a door frame It is natural that steel doors for cottages or apartments made of two thick steel sheets are stronger and more reliable. However, how the box itself is made is also important. The lightweight construction, welded from metal strips and corners, is not able to provide adequate protection. The box should be created from a steel profile or even rectangular pipes. When trying to break in, the bent profile or pipe resists deformation, literally "stand to death". But the stripes and corners crumple quite easily.The stiffeners of high-quality products are made of the same material, that is, steel profile or pipe. It is good if the edges go both vertically and horizontally. In this way, as a rule, insulated external metal doors are made, where the internal reinforcing grating simultaneously serves to evenly distribute the insulation throughout the entire service life.The horizontal stiffening resists squeezing the door leaf and pushing it inside the door frame. Vertical ribs protect against twisting loads that occur when trying to bend the upper or lower corner of the fabric of the product from the lock side.How the stiffeners affect the price of the door- Inexpensive steel doors manufactured in Russia have only two horizontal reinforcements. Therefore, they are easy to crack from the side of the lock. And it is also easier to squeeze, push inside, than a structure with a large number of stiffeners.- For extra reliability, expensive models are reinforced diagonally, thus protecting them from compliance with twisting loads of different types.- The holes in the end of the door for installing the lock are the weak point of the design, so a high–quality entrance or entrance door is provided with a steel overlay in this place.By installing a solid door, the owner of the apartment is more likely to protect himself and his property from the encroachments of intruders. Burglars only need one cursory glance at a metal barrier to understand the meaninglessness of attempts to quickly enter your territory.
