Types of hinges There are generally two kinds of hinges for household wooden doors, one is a flat hinge and the other is a letter hinge; Check and choose hinges: for wooden doors, hinges are more stressed; Moreover, the ball bearing (the knot in the middle of the rotating shaft) should be selected, because it can reduce the friction at the joint of two hinges and make the wooden door open smoothly without creaking.
It is not recommended to choose the' son-mother' hinge on the wooden door, because it is relatively weak and is designed for light doors, such as PVC doors, which reduces the process of opening grooves (assembling hinges) on the door.
Material and appearance of letter hinge
Hinge materials are stainless steel, pure copper and stainless steel/iron. 304# stainless steel is recommended for home use, which can keep the door used for a long time. It is not recommended to choose 202 #' Immortal Iron' or something like that. Although it is cheap, it is mixed with good and bad, and rust is very troublesome. Finding someone to replace the hinge is not only expensive but also troublesome. Note that the screws used for hinges should also be matched with stainless steel screws, and other screws should not be used casually. Pure copper hinges are suitable for luxurious wooden doors, but they are not suitable for ordinary families because of the price.
Now the electroplating technology is very mature, and stainless steel also has various color appearances, which can be matched with different styles of wooden doors. Of course, the most important thing to take care of is the brushed appearance, which is more environmentally friendly. The pollution of electroplating industry is also quite serious.
Specification and quantity of stainless steel appearance hinges
Hinge specification refers to the length, width and thickness of the hinge after opening. Generally, the length and width are calculated in inches, such as 4 "x4", that is, the length 100mm X width 100mm. The thickness is generally calculated in millimeters, such as 3 mm The hinge of a common household wooden door is 4 "or 100mm long; The width depends on the thickness of the door, and the 40mm thick door is equipped with 3 "or 75mm wide hinges; The thickness is calculated according to the weight of the door. If it is light and hollow, and it is easy for a person to lift it, use a 2.5mm thick hinge. If it is solid, use a 3 mm thick hinge. To sum up: the specifications of the hinge * The length and width of the hinge on the market are not special standards, and it doesn't matter if it is a little bigger; The most important thing is the thickness of the hinge, which must be thick enough (3mm). It's best to measure it with calipers, because the thickness of the hinge not only determines the strength of the hinge, but also implies whether your hinge is high-grade or not, whether it is really stainless steel (hidden rule).
A light door with two hinges is enough; Choose three hinges for heavy wooden doors to keep them stable and reduce the deformation of wooden doors.
Installation position of hinge
Needless to say, there are two hinges on the wooden door, that is, three hinges will have patterns. One is that the middle hinge is close to the upper hinge, which is German-style: the hinge is installed like this. The advantage is that it is quite stable, and the stress of the door frame on the door leaf is better, but it is not particularly necessary. As long as the correct hinge is selected in the above way, the force is enough. If the door is particularly heavy, install another hinge directly.
The other is basically an ordinary device, American:
Average score of hinge installation
It is suggested to install the hinges evenly, which is more beautiful and less utilitarian. In case the door is a little deformed, the hinge will also play a more restrictive role.
