In daily life, the most common combination of door hardware accessories are hinges, locks, and door closers. Among them, the hinge is a suspension device, which is one of the important door hardware for the door to work normally.
How should we determine the proper door hinge? Understanding the following pieces of information can help you find the proper type of door hinge.
1, What is the door material (wood,stainless steel,fiberglass,or hollow metal)?
2, What is the frame material (wood,stainless steel,hollow metal,or 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 half surface and half mortise hinges?
Just remember that the door is the key element.
Whichever way the hinge installs onto the door is used as the name.
Thus the hinge which is mortise on the door and is surface on the frame is a half mortise hinges.
Different weights and different types of doors should use different hinges. The proper door hinges can not only maximize the usefulness of the door, but also extend its service life.
