achieve the required strength and account for the thicker glazing
(discussed below) you’ll generally need a much deeper profile to house
all the elements of the frame.
In addition a strong wood is needed to ensure the big frame remains strong over the life of the frame.
To add extra rigidity we can also add spline joints to the corners of
the frame. This is much stronger than the usual method of joining
frames, which uses special framing pins and wood glue.
Splines involve creating interlocking sections of wood to add
friction and a difference in grain directions. The splines can be made
into a feature of the frame by using different woods or finishes to
create contrast and add interest to this construction element.
If extra strength in the profile is required we can add steel angle
brackets to the internal corners of the frame. We first create a routed
out groove so the internal components (glass, mount, artwork etc) all
site flush against the frame internal. Then add the angle bracket,
screwed to the frame.
With oversized frames you’ll need thicker glazing. We use 4-6mm for large frames, depending on the exact sizes involved.
Glass is not recommended as to get the strength required at that size
you need very thick glass. This makes the frame weight so much it can
take 3 people just to lift it, in addition to special hanging
So acrylic is the usual method for glazing oversized frames.
String or wire will not have to strength to hold an oversized frame. There are several valid options:
2 Metal fixings, each using multiple screws are attached to the back
of the oversized frame. 2 corresponding hooks are screwed into the wall,
and the frame is hung on these.

2 brackets, one on frame – 1 on wall. Joined with metal bone. Up to 100kg
Best for completely flat walls. Gives seamless, flush visual.
Subframes are essential for oversized work. They provide much of the
structural stability, particularly if the main profile is thin.
There will likely be additional support struts to further maintain
the rectangle shape of the sub frame. Up to 2 horizontal and 2 vertical
support struts are used. These are of course behind the frame and never
seen when the art is displayed.
To produce very large picture frames takes some large machinery. You can read more about the workshop on our Company page. Here are some highlights:
- 62 inch HP Giclée printer
- 1.5m laminator
- 1.7m Hotpress
- Special workshop setup for large framing
- Professional spray booth for finishing large frames
