Buying a steel door is a desire to protect one's home from strangers, securely shielding yourself and your family in a "fortress". Whatever you say, but steel is solid. Today, the choice of steel entrance doors is simply huge, it includes the choice of the main material, insulation layer, external cover, accessories, locks, design. So, in addition to a purely protective function, the steel door can still be an individual calling card for you and your home.
How to choose a steel front door?
The choice of a steel entrance door is carried out by many criteria. First of all, the quality of the material of manufacture. Also it is necessary to pay the main attention to the reliability of the locking system. And, last but not least, the visual appeal - no doubt, the door should approach the interior of your home.
Let's talk about each criterion in more detail:
- Material for steel entrance doors to the apartment . The very basis of the door can be made not only of steel, but also of aluminum. Of course, steel is superior to aluminum in many respects, including noise insulation, strength and thermal insulation. But aluminum - lighter, so that deliver and install them easier. In addition, aluminum is better to process, so that with them you can implement any ideas for design. And, of course, aluminum doors are cheaper than steel doors.
- External finishing . Both outside and inside the metal door can be finished with one of the options for finishing materials: plastic panels , MDF panels, powder coating, paint and varnish, wood, leather and imitation leather. The choice of finishing is always with the owner.
- Locking mechanism and way of opening the door . Depending on whether you want the door to open outward or inward, and also from which side the handle should be, the doors are right, left, inside and inside. Also, you have a choice of the quality of the locks themselves, and if you went to buy a solid steel door, then there is no point saving on locks - choose reliable modern systems. Of course, you do not need a 13th class of crack resistance, but you can not stint on class 4. A novelty today is biometric locks, in which a fingerprint is used instead of a key, but so far they are not so widespread.
- Fittings - another important criterion for choice. Cheap hardware will in no way adorn your expensive door, besides, it will not last long and will require replacement. It is better to immediately get reliable handles, chains, eyes and all sorts of decor elements.
- Heat and noise insulation . Steel entrance metal doors with sound insulation are an added plus. This criterion is provided by fillers, which may be mineral wool, corrugated board or expanded polystyrene. Good quality mined doors are used in expensive doors.
Types of steel for metal doors
Thin metal is used by Chinese manufacturers in its low-cost products. It is very unreasonable to acquire such doors as input, because they absolutely can not guarantee the reliability and safety of the dwelling from break-ins and penetrations. On the Internet there are a lot of videos that clearly demonstrate how a child can open a lid for a lid with such a door, without much effort.
Another thing is thick steel. The main difference here is hot or cold rolling. Depending on the particular treatment method, the material has different properties:
- hot-rolled metal has a dark color, which is not visible under the decorative coating, it is more susceptible to corrosion, so it has a lower cost, in documents to the doors of such material will be listed in GOST19903;
- cold-rolled alloy costs more, has the color of galvanized steel, is not subject to corrosive processes, has GOST19904.
