The hinge is one of the most active components of a door unit in combination with door locks, exit devices and door closers. Generally speaking, if the right hanging device is not selected, the door will not function properly.
How do we determine the proper type of hinge?
There are several pieces of information needed to choose the right type of hinge.
1, What is the door material (wooden or metal)?
2, What is the frame material (wooden or metal, channel iron)?
There are four classifications of hinges: Full Mortise, Half Mortise, Full Surface, Half Surface.
1.Full Mortise Hinge
The full mortise hinge is the most common in use today. One leaf is mortised into the door’s hinge stile and the other leaf is mortised into the frame. Only the barrel can be seen when the door is closed. Full mortise hinges can be used on aluminum, hollow metal and wood doors and frames.(WD or HM X WF or HMF)
Full mortise hinges were formerly referred to as butt hinges because the two leaves of the hinge abutted when the hinges was in the closed position.
2.Half Mortise Hinge
With the half mortise hinge, one leaf is mortised into the hinge stile of the door and the other leaf is offset for surface mounting to the door frame. The surface leaf on the frame can be seen when the door is closed. Half mortise hinges are commonly used with channel iron frames, which require that the leaf on the frame must be surface mounted.(HM X GIF)
3.Full Surface Hinge
The leaves of a full surface hinge are applied to the face of the door and frame. However, the frame leaf is narrower than the door leaf to accommodate limited frame conditions. The entire hinge is exposed to view when the door is closed. Full surface hinges are made to accommodate the inset of the door in the frame. Full surface hinges are most frequently used with kalamein wood doors or doors of tubular steel mounted to channel iron frames.(MCD or HM X GIF)
4.Half Surface Hinge
The half surface hinge has one leaf offset for surface mounting to the door and the other leaf is mortised into the frame. When the door is closed, you can see the surface leaf on the door.(WD X WF or MCD X HMF)
How do you remember the difference between a half surface and a half mortise hinge?
Just remember that the door is the key element.
Whichever way the hinge installs onto the door is used as the name.
Thus, a hinge that is mortised on the door and faced on the frame is a half-mortised hinge.
Select the Proper Weight and Bearing Structure
Two factors determine the weight and construction of hinges: the weight of the door and the frequency of use.It is advisable to include the approximate weight of the additional hardware that will be mounted on the door.
Heavy Weight - Ball Bearing
Example: DDSS001, 4.5" x 4.5" ( 114.3mm x 114.3mm ),US32D
Standard Weight - Ball Bearing
Example: DDSS001, 4-1/2" x 4-1/2" ( 114mm x 114mm ),US32D
Standard Weight - Plain Bearing
Example: DDSS004, 4" x 4" ( 102mm x 102mm ),US32D
Different weights and types of door hinges should be used on different doors. The right hinge will not only make the most of the door but will also extend the life of the door and reduce the increase in costs at a later date. stainless steel hinges from D and D HARDWARE have undergone rigorous safety testing (including BS EN, CE, UL, ANSI and BHMA) and are available for educational, medical, hospitality, residential and commercial applications.
