ASSEMBLY OVERVIEW
These instructions are designed to guide you though the process
of building your new garden shed. It is a simple process of joining
sheets together before adding top and bottom channels to form a
shed panel. These panels are then joined together to make your shed.
When fitting the channels to the sheets, the high side of the channel should go on the inside of the sheet, ensuring that
any water that collects in the bottom channel will run over the lower side and run away rather than into the shed.
Rivets are fitted by drilling through outside of the channel into the ribs of the sheet, usually at every second rib. It is
also important to fit at least one rivet per sheet from the inside of
the channel into the pan of the sheet, close to a rib. Extra rivets
should be fitted on the inside of the channel into the pan of the
sheets in high wind areas.
It is critical that you remove the swarf (the metal filings created
when drilling) from the panels and channels as you assemble
them as these will rust quickly and could cause corrosion issues
with your shed!

STEP 4: 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).

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.
(We recommend you use an 8mm shackle diameter padlock on these pad bolts,
anything smaller may create security issues.)
A Drill and rivet here.
B Drill through to the underside.
Rivet top and underside.

Channels will come
short of the ends of the

all panels.
To hinge the door on the
opposite side, put the top
channel on the bottom and
the bottom on the top.
Put the padbolt on the
door before erecting the
panels. It will stop the door
swinging around!
GARDEN MASTER TIP
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.

GARDEN MASTER TIP
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).
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 50mm 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 panel, lift it over the top of your upright walls and
lower down on top. Once the roof is sitting on top of the walls and the roof panel has a
minimum of 50mm overhang from the back wall, drill, and rivet through the L flashing
at each end of the roof. Drill and rivet 150mm from the front or back wall as shown in
diagram 9.
A larger amount of overhang is required on the high side of the shed for weather
protection. Once you have located the roof panel you can then finish off riveting the
ends of the roof 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.
Make sure to clean ALL swarf from your roof once you
have finished installing the roof panels. left over swarf
will cause surface rust spots on your shed.

GARDEN MASTER SHED OPTIONAL EXTRAS
IMPORTANT: FIXING 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.
• 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. Phone [phone] for free advice or
see page 7 for more details.
