Door hinge is the most common door accessory device, which connects the door frame to the door leaf and allows rotation between the two. The hinge can bear the weight of the door without causing the door to sag, and can make the door to rotate freely for a long time under the lowest frictional resistance.
There are many materials for hinges, such as stainless steel, zinc alloy, steel, and brass. Hinges of different materials have different ranges of use. The choice of hinge has a large influence on the use of the door. If the hinge is improperly installed, the role of the door will be difficult to play, and even serious situations may endanger life. In order to maximize the hanging and controlling of the door, it is important to choose the right hinge.
We analyze the choice of door hinges from the following two aspects
1. The material of door hinge
2. The usage range of door hinge
1. The material of door hinge
Stainless Steel Hinge—The material of stainless steel hinge is hard and not easy to rust. Often used in outdoor or high-temperature corrosive environment. Suitable for installation in fire rated doors and escape doors.
Steel Hinge - The steel hinge has high hardness and high strength, but it is easy to rust and requires surface spraying.
Brass Hinge - Brass hinges have low strength, poor corrosion resistance and low melting point, so they are not suitable for fire doors.
Aluminum Alloy Hinge-Aluminum alloy hinges have the lowest strength and poor corrosion resistance, the surface treatment of door hinge needs to be sprayed or anodized.
Iron Hinge - The production cost of iron hinges is cheap, but the iron hinges have poor corrosion resistance. Therefore, it is not suitable for installation on outdoor doors.
2. The usage range of door hinge
Stainless steel hinges are available in SS201, SS304 and SS316.
Doors in industrial environments require a high level of security for unconventional use. Rapid evacuation and fire zone isolation in emergency situations can prevent the spread of fire. The ANSI/CE certified 201 or 304 stainless steel hinges meet the requirements of the working environment, as well as excellent corrosion resistance and long-term trouble-free use.
High-end commercial/hotel/school environment doors are used for high-frequency entry and exit, and stainless steel doors are used in accordance with the requirements of rapid evacuation and flame retardancy in emergency situations. In order to maximize the role of the door, it is necessary to use certified 201/304 stainless steel hinges and ANSI/EN, so that the door can be stably suspended for a long time in high temperature environments without failure.
Doors in a medical setting must consider a large flow of people, high frequency of use and convenience, and require an ANSI/EN certified and stainless steel 304 hinge that prevents the patient from using the door to make dangerous behavior/corrosion resistant chemicals.
Doors in the long-term, highly corrosive environment at the seaside require the use of a 316 stainless steel hinge with corrosion resistance.
In order to prevent the brass from oxidizing in the air, the surface of the brass hinge is treated with a layer of varnish. There is also a brass hinge, which has been specially treated without any treatment to deliberately oxidize the brass to give it a natural oxidation effect. The brass hinges are very decorative and suitable for decorative doors.
Steel hinges can be used for fire doors, but surface spray treatment is required for interior doors. Such as: residential security door.
Aluminum alloy hinges are suitable for lighter doors such as residential aluminum doors or plastic doors. Due to its low melting point, it is not suitable for fire doors.
In order to better play the effect of the door, it is necessary to select the door hardware with the corresponding function according to the use scene, environment and other factors. The normal start and close of the door are inseparable from the tacit cooperation of each door hinge. Different door hinges should be selected for different environments. The material of the selected door hinge should match the environment in which the door is located. D and D HARDWARE 's stainless steel door hinges are ANSI/EN certified and have a high resistance to corrosion and are suitable for use in education, healthcare, hospitality, residential and commercial applications.
D and D HARDWARE can also provide customers with door hardware solutions in different environments.
