How Much Do You Know About the Type of Door Hinge?

Generally there are two types of hinges for household wooden doors, one is a flat hinge, and the other is a letter hinge. If you choose a flat brass hinge for a wooden door, it is more stressed. And you should choose a ball bearing with the shaft in the middle, because it can reduce the friction between the two brass hinges and make the wooden door open smoothly without squeaking. It is not recommended to use the composition brass hinge on the wooden door, because it is relatively not very strong. The design is used for light doors, such as PVC doors, and it is to reduce the number of grooves to fit hinges on the door.

 

The material and appearance of the hinge

 

Generally speaking, the hinge materials are stainless steel, brass, stainless iron or iron. Among them, 304# stainless steel is recommended for household use, which can keep the door in use for a long time. It is not recommended to use 202# immortal Iron and so on. Although it is cheap, the quality cannot be ensured, and it is troublesome if it gets rusty. What is more, the labor of finding someone to replace the hinge is not only expensive, but also troublesome. Note that the screws used in the hinge should also be matched stainless steel screws, and other screws cannot be used. The brass door hinge is suitable for luxurious log doors, but the price is not suitable for ordinary households, since the price of brass hinge is little high.

 

Now the electroplating technology is very mature, stainless steel also has various colors and appearances, which can be matched with different styles of wooden doors. Of course, it is best to take care of the brushed appearance, and it is more environmentally friendly. After all, the pollution in the electroplating industry is also quite severe.

 

Specification and quantity of hinges

 

Hinge specifications refer to the dimensions of length x width x thickness after the hinge is opened. Generally, the length and width are calculated in inches, such as 4"x4", that is to say, length 100mm x width 100mm. The thickness is generally calculated in millimeters, such as 3mm. For general household wooden doors, you can choose hinges that are 4" or 100mm long, and the width depends on the thickness of the door. Usually 40mm thick doors are equipped with 3" or 75mm wide hinges, and the thickness is calculated according to the weight of the door. For the light and hollow doors for easy lifting, you can use 2.5mm thick hinges, and 3mm thick hinges are for solid and heavier ones. Therefore, if the length and width of the hinges on the market are not particularly standard, and it is slightly larger, it does not matter. The most important thing is the thickness of the hinge, which must be thick (>3mm), it is best to measure it with a caliper, because the thickness of the brass hinge not only determines the strength of the brass hinge, but also it hints that the hinge bought is up-grade or not and whether it is really stainless steel or brass material hinge.
