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

flush with sheeting (diagram 4) and put one rivet in the centre to hold the ‘L’.
Rivet the corners through the channels and one more between the corner
and the centre rivet. Perform the same at the other end.

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).

GARDEN MASTER TIP
STEP 6: INSTALLATION
WALL ASSEMBLY
Stand up the back wall and as your helping hand is holding it up, bring the left end
wall in to meet it at the left corner (diagram 6) overlapping the corners (diagram 7).
Drill and rivet at approximately 100mm down from the top and up from the bottom,
drilling and riveting from the outside.
Bring the right end wall into the right back corner and perform the same again,
checking to make sure the walls are sitting flat at the bottom. Bring the front wall into
place and join the front corners to the end walls, same as the back (diagram 8).
Finish joining the corners by riveting at approximately 200-300mm apart. You will
find it easier to drill these corners if they are supported on the inside (see tip).
FIXING THE ROOF
With a person at each end of the roof, lift it over the top of your upright walls and
lower down on top with an overhang that looks best to you (diagram 9). At the left end
rivet through the ‘L’ flashing into the top channel of the left end wall.
Measure the overhang at the back and rivet the right end ‘L’ to the right end wall
with the same overhang as the left end. If it is difficult to get the same overhang at
each end, this will be caused by an unlevel site or walls that are not square. Adjust
accordingly. Rivet the ‘L’s at 300mm apart.
Using the ladder and the tape measure, rivet down through the top of the roof, through
the pan into the top channel of the front and the back walls (10mm more than the
overhang). Rivet beside every second rib. You will not need to worry about these rivets
leaking as any water seeping through will end up on the outside of the walls.
FIT THE DOOR BRACES AND INSTALL SHED
Fit the door braces, if not already done so. Check that all filings/swarf is removed.
BUILDING YOUR SHED
The basic task is to join the sheets together
to form your panels, then rivet the channels
to the top and bottom of these panels. They
will then join together to form your shed
(diagram 6, 7, 8 and 9).
IMPORTANT:
FIX YOUR SHED TO ITS FOUNDATIONS
If your foundations are unlevel or bowed, you will have problems with
your padbolt and door levels. This can be fixed by slipping a spade under
either door jamb and lifting. You will soon get a feel for which side needs
propping up.
IMPORTANT:
• Do not attempt to assemble panels in rain or windy conditions.
• Make sure your foundations are squared and level before erecting panels.
• It is easier to remove all swarf (filings) before you stand your walls up.
• Complete all panels before erecting your shed.
• Keep a firm grip on panels when handling. If they slip they will cause damage.
• Always wear non-slip gloves, protective footwear and eyewear.
It is essential that every shed has a floor, but the only way to make sure your
shed is there to stay on windy sites is with a recessed concrete floor.

For existing flat concreted areas
using dyna-bolts. (Bolts need to
