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!

YOU WILL NEED:

1 x 1815mm top channel

1 x 1815mm bottom channel

STEP 1: BACK WALL

1. Join 2 1

sheets together with 2 rivets through the overlapping

ribs making sure the ends of the sheets are flush.

2. Cap sheeting with

channels putting the cutouts top

and bottom. This will finish 10-15mm shorter than the sheet.

3. Rivet the channels through the end ribs and every 2nd rib between.

4. Make sure you put at least 1 rivet per sheet up through the underside

of the channel into the pan of the sheet.

2 x 1980mm ‘L’s

STEP 2: ROOF

1. Join 2 1

1980mm sheets together, same as the back.

2. Cap sheeting with

1815mm channels.

3. Rivet the channels at every second rib but

not the corners at this stage.

4. Place the short flange of the ‘L’ on top of the rib at one end. Make

sure ends are flush with sheeting (diagram 1) 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. 5 rivets for each ‘L’.

STEP 3: END WALLS

1. Cap the sloping sheets

with

1815mm 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.

YOU WILL NEED:

4 x sloping sheets and 2 x

sheets

for end walls (2

left, 2

right)

4 x 1815mm channels for end walls

(2 per side)

Channels will end 15-20mm short at tops

of end walls and 10-15mm at bottoms.

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).

STEP 5: FRONT WALL

1. Slip

290mm wide sheet with door jamb under door. Use

door spacer to

determine the correct opening size by placing on the bottom flange of the door

jambs. Then rivet

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.

(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.

A B

Channels will come

short of the ends of the

sheeting by 10-15mm on

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 0800 807 433 for free advice or

see page 7 for more details.
