Hinges for plastic doors are important elements of the balcony structure. In most cases, apartment owners install plastic products, such as windows and doors, on the loggia or balcony.
They are fixed with special hinges, which must, of course, be strong. The reliability of the entire structure will depend on this. They can withstand heavy loads over a long service life, although sometimes they require regulation.
At the time when hinges for PVC doors are made, a durable material is used, which increases the reliability of the fastening. It is important to pay special attention to these elements when buying canvases.
Varieties and device
Choose hinges for doors from quality alloy
At the time of purchasing plastic structures, it should be remembered that hinges can have different types and characteristics:
- When choosing door hinges, you need to familiarize yourself with the requirements of the entire structure as a whole. Only after that it will be clear what elements are required.
- Theoretically, plastic windows and a canvas perform the same function, the only difference is in size. Due to this, for a plastic door, the fasteners must be of a more durable type.
- For doors, a hinge that is made of aluminum alloy is better suited. Due to the strength of the material, the reliability of the fastening will increase significantly.
- At the time of buying balcony doors, it is best to choose fasteners that have a regulation function. Thanks to this, it will be possible, if necessary, to adjust the structure vertically or horizontally;
It is important to remember that during operation, the fastening mechanisms that are responsible for opening and closing doors must be lubricated from time to time. The quality of the construction service will depend on this.
Classification
Products of this class have various types, which are classified according to several criteria. As a result, the hinges on plastic doors differ in the following parameters:
The sash width is distinguished:
- products for a narrow profile, up to 90 mm;
- products for a wide profile, up to 110 mm.
Depending on the withstand loads:
- for a narrow profile, products that can withstand up to 80 kg are used;
- for a wide profile, products are used that can withstand up to 160 kg.
Overlap width:
- products with lining;
- products designed for use with wide weld beads.
By installation method:
- any manufacturer of products for PVC profiles uses its own fastening system. As a result, fastenings on plastic doors are fixed using a special template, which is designed to facilitate the fastening process.
Based on the material of manufacture:
- the body of the product is made of zinc alloy or aluminum;
- pins and inserts made of stainless steel or an alloy of ferrous metals;
- spacer sleeve made of super strong plastic or Teflon;
- fasteners are made of galvanized or stainless steel.
By the number of regulation methods:
- PVC door fasteners have three ways of regulation: height, horizontal position and quality of clamping.
In addition, door products differ in design and color, which is explained by different manufacturing technologies and manufacturer capabilities.

Additional accessories for the balcony door
The presence of these fittings is optional. The decision on their need to increase the functionality of the door structure is made by the owners of the house or apartment.
Opening limiters
These popular accessories can be classified into three groups:
- The “comb” limiter helps to choose the optimal gap between the open door and the frame for comfortable ventilation of the room in any season and weather. With the help of the "comb" the door is fixed in the desired position.
The comb can be bought at a hardware store - A cable lock-limiter can also fix the sash in a certain position.
- A door handle with a key blocks the opening of the sash in case of unauthorized entry and helps to keep children safe.
Replacing the hinges
If, after installation, a breakdown occurs due to the fault of the manufacturer, then it is necessary to replace the part that is out of order. To do this, you need a specific list of tools:
- thin type pliers;
- small hammer;
- screwdriver.
Upon purchase, each structural element is accompanied by detailed instructions for assembly and disassembly, and it looks like this:
- the bar is dismantled, which is located on top of the structure;
- the axle mechanism is partially knocked out;
- using thin pliers, you need to pull it out;
- the door leans towards itself very neatly;
- then you need to slightly raise the door leaf and remove it from the existing hinges.
After completing the presented sequence, you should dismantle the failed part, after which, in the reverse order, we bring the product back to its original appearance. For more information on how to change a plastic door and hinges, see this video:
Strict adherence to the attached instructions allows you to easily replace defective parts and competently perform periodic repairs, which will positively affect the operation of the entire structure.
What to do with rusted hinges?
Long-term use of the door can lead to the formation of rust on the hinge mechanisms. In such cases, it is important to remove the canvas from the hinges without sudden movements.
Do not use a hammer or other tools when trying to break the rust layer on the fasteners. Such manipulations will only aggravate the situation.
The solution will be a special aerosol that can remove plaque within 6-12 hours after application. As soon as the mechanisms are cleaned, they begin to work with them according to the instructions for dismantling.
