Installation Instructions

STEP 15: INSTALLING GABLE END SHEET METAL PANELS
INSTALLING BACK WALL PANELS:
If your building is 12’, 24’, or 30’ wide start in the middle of the building and work to the sides. See the panel
layout drawing on page 33 or 34 for your size building. The drawing will give you the panel lengths and loca-
tions. If your building is 20’ wide, see the panel layout on page 32.
Start by placing the under lap edge of the first panel flush with one edge of the back center frame post on the 12’ and
24’ wide buildings. On the 30’ wide building you will need to measure and mark the center of the building on the girts
and base rail. Make a mark 1” to the side of the center marks. This will be the edge of the first under lap rib of the first
panel.
On 20’ wide buildings, locate the center major rib of the first panel 4 1/2” from to the left of the building center.
The length or height of the sheet metal panels are sized to fit your building. (See drawing on page 32, 33 or 34 for your
building size and panel lengths). To cut the roof angle on the top of the panel measure down on the outside edge of the
panel 9 1/2” and make a mark. Now, draw a line between the upper corner and the mark. This will be the angle cut for
the roof pitch. On the 20’ wide buildings, first panel, see the layout on page 10. On all additional panels use the 9 1/2”
measurement down one side as described above. Cut with large straight cut tin snips
. Fasten the first panel to the back
girts with 3/4” painted self-drilling screws with rubber washers. Do Not place any screws next to the overlap rib
until you
lift and insert the under lap edge of the next panel in that direction.
On 12’, 24’, and 30’ wide buildings
the second back panel will also start in the center of the building with the overlap rib
in the center of the building. Measure and cut the top of this panel opposite of the first panel. (The overlap rib will be the
top corner measurement and the underlay rib will be the low measurement.) Note that panels going to one side of the
building will lap under the previous panel. You will need to leave out the screws in the overlap rib until the next panel is
installed. On 20’ wide buildings
, the second panel can go to ether side of the first panel.
Measure and trim the top angle on the remaining panels as you did the other panels. (9 1/2” down one side and up to
the opposite corner) When you get to the sides of the building trim the last panel to be flush with the building frame.
(NOTE: The edge can extend out about 1 3/4” and still fit under the corner trim.)
INSTALLING FRONT WALL PANELS:
Measure, mark, and cut the top angle on the front panels as you did the back panels. You can either measure and cut
the door openings or put the panels up against the building, mark the door openings, take the panels down and cut the
door openings. If you place the panels against the building to mark the door opening add 1 1/2” to the opening marks to
leave a 1 1/2” space between the inside of the door frame and the edge of the sheet metal panels. This will leave room
to install the door trim later. Install only one or two screws in the lower edge of the panels over the door at this time.
These screws will be removed and reinstalled when door trim is installed. (See page 41)
Cut the horizontal across the ribs with large straight cut Tin Snips first. To make the vertical cut you can use a straight
edge and a Utility Knife. Score the metal with a sharp utility knife the full length of the cut and bend the discard part of
the panel away from the score until it brakes off. You can also use Aviation Snips or a circular saw with a metal cutting
blade to make the vertical cuts. (If you use a circular saw be sure to wear eye and ear protection.)
