IMPORTANT!
• Remove the swarf (drill filings) from the panels as you assemble them.
• All components are cut to length. Do not cut any parts unless instructed.
• Rivets through the inside of the channels into the sheeting are just as important
as rivets from the outside.
RIBS AND PANS
• Generally most rivets are spaced at 300mm apart.
• Keep the rivets in the pans as close to the ribs as possible for added strength.
• Ribs will always protrude to the outside of the shed.
• Extra internal rivets are strongly recommended in high wind areas.
DIAGRAM 1 DIAGRAM 2 DIAGRAM 3
BUILDING YOUR SHED
The basic task is to join the sheets together to form your
panels, and rivet channels to the top and bottom of these
panels. They will then join together to form your shed
(diagram 1, 2 and 3).

STEP 1: FRONT WALL
1. Slip
D
330mm wide sheet with door jamb under door. Use
I
door spacer to
determine the correct opening size by placing on the bottom flange of the door
jambs. Then rivet
G
channels to tops and bottoms of sheeting.
2. Outside: Rivet channel at corners and every 2nd rib between and through door
jambs and spacer.
3. Inside: One rivet per sheet at each end up through channel underside and
through door jambs and spacer.
Rivet padbolt to the outside of door using wide flange rivets supplied.
Channels will come short of the ends of the
sheeting by 10-15mm on all panels.
ADoor jamb fits inside bottom channel.
BDoor spacer fits inside door jamb but
to the outside of bottom channel.

The higher side of the channel goes to the
inside of the shed. It is very important to
include the rivets on the underside of all the
channels as they are structural
(except roof channels).
FITTING CHANNELS

INSIDE
The cutouts go to the inside of the panel to
allow easy fitment of the end walls
on assembly.

Rivet
To hinge the door on the opposite side,
simply put the top channel on the
bottom and the bottom on the top.
Put the padbolt on the door before

B
with
F
1515mm channels.
2. Rivet the channels at the corners and every 2nd rib in between.
3. 2 rivets up underneath through channel into pan of sheet.
4. Perform the same again for the other end.

4 x 1980mm - 1830mm sloping sheets
(2 left, 2 right)
4 x 1515mm channels for end walls

STEP 5: DOOR BRACES
1. The door braces can be riveted now or after you have
assembled your shed.
2. Tuck one end of the ‘Z’ between the bottom channel of the
inside of the door and the sheet. Do the same at the top,
overlapping in the centre behind the padbolt.
If you have a locking ‘T’ handle you will have to run the
‘Z’s the opposite way to the diagram.
3. Rivet the ‘Z’s at the ends, and in the centre of the channel
it is tucked under, and through the overlap in the centre.
Two or three more rivets will be required through the door
sheeting into the ‘Z’, but they will need to be riveted through
from the outside of the door for a neater appearance.
4. You may need to cut or bend the flange at the bottom
and the top of the ‘Z’ if it catches on the door jamb when
opening or closing (diagram 5).
