| Installing a steel door cause troublesome, requiring | | | | width, for a total of 2000 mm. So, the door leaf, |
| experience and specific skills. However, if you do | | | | necessary in this case, should have a size of 800 |
| decide to install the door yourself, you should read | | | | mm to 2000 mm. |
| with a lot of rules. | | | | Furthermore, it should pay attention to the floor in |
| First thing that starts the installation on any door - | | | | a room where it will be installed steel doors with |
| a measurement of the opening. Take the roulette | | | | powder coating. If there is no cover and tie, you |
| wheel, a pen or pencil and paper to record the | | | | need to determine how the zero level after the |
| results and calculations. First, measure the width | | | | final assembly floor, and take into account the |
| of the doorway. Better to do it on the floor, | | | | number in the calculation of height of the |
| from one side to the other, to measurement was | | | | doorway. |
| carried out strictly horizontally. On a side slope of | | | | Then, to select a suitable door frame, measure |
| the doorway should measure its height and record | | | | the thickness of the walls of the room. For |
| the results. | | | | measurements using calipers. Also suitable and |
| For a standard room will be equal to the width of | | | | two lines or plate, which must be attached to |
| the gap from 800 mm to 900 mm and height | | | | different sides of the same wall so that their |
| about 2070 mm, sometimes 2100 - 2300. But the | | | | edges were in the doorway. The distance |
| resulting dimensions are not the size you required | | | | between them is the thickness of the wall. The |
| door leaf. | | | | width of the door frame should be picked as |
| To determine its size should be a series of | | | | close as possible to the width of the wall. Do not |
| calculations. Take an average width of the opening | | | | forget to take into account the state of walls: |
| - 900 mm. Of this number, we must subtract the | | | | their thickness may increase due to mud, wall tiles |
| width of the door frame (usually it is equal to 30 | | | | or cladding panels, etc. |
| mm) multiplied by 2 (left and right hand box): 900 | | | | Then you can boldly go buy a door unit. In making |
| - 25 * 2 = 850. Round the result obtained to the | | | | a choice, do not forget that each manufacturer |
| nearest multiple of 100 fewer. In our example, it | | | | provides concordances doorways and their |
| will be 800 mm. | | | | standards of door panels. If you chose the |
| The remaining 50 mm will be used for | | | | company has no product that fits your size, do |
| technological gaps when installing. In order to | | | | not rush to produce the door to order. This will |
| calculate that the door height should also use the | | | | cost you much more. You can find the door block |
| average value - 2070 mm. So, 2070 mm - 25 | | | | a little smaller, but the difference will disappear in |
| mm (width of the box top), minus 20 mm on the | | | | the technological openings during the installation. |
| technological gaps - is 2030 mm. Rounds as the | | | | |
