Oil Canning Reduction Trim on CF Panel
OIL CANNING
What is Oil Canning?
Oil canning is described as a wavy appearance often
occurring in the flat areas of formed metal products,
such as metal roofs. The structural integrity of the metal
is not affected by oil canning – it’s simply an aesthetic
issue. The term oil canning is an industry standard used
to describe this occurrence and is not a reason for
rejection.
Things to Expect
• If the deck is bowed up or has a belly, the new
sheets will oil can.
• High temperatures are often a factor when
waviness occurs. Once it gets cooler, the effect
will likely diminish.
• Changes in light – including overcast days, shade,
and intense sunlight – can affect the appearance
of oil canning. Oil canning will seem less
prominent in the shade but will be more
noticeable in brighter light.
• The color of the metal panel can also affect the
appearance of oil canning. For example, oil
canning is more evident on galvalume, copper or
other metallic colors.
1. Prior to applying the panel, the oil canning reduction
trim should be positioned on the decking so that the
trim is centered in the flat section between the ribs of
the panel when it is applied.
2. The trim should be positioned to start 3’ from one end
and stop 3’ from the other end of each panel.
3. The trim should be held in place by screwing through
the trim into the decking at each end of the trim piece.
4. Reduction trim sections are 12’. These should be field
cut to length as needed. All joints should be butted not
lapped. Drops need to be utilized.
The purpose of this application is to reduce the effect of oil canning on the Mueller CF panels. It will not completely eliminate
oil canning on these panels. The strip must be applied down the flat section of the panel.
