Step 1: Back Wall: Select one 4.210m Base Plate (Green), one
4.210m Top Plate (Red) and six Studs (Yellow). Lay out Plates
and two Studs on a flat surface and nail together using two
75mm nails per join. Nail in remaining centre studs using Nogs
to get correct position. Position Nogs .883m below Top Plate
and nail in place. (All Plates, Studs and Nogs are joined to-
gether with two 75mm nails each end).
Step 2: Front Wall: Select one 4.210m Base Plate (Green), one
4.210m Top Plate (Red), four Studs (Yellow) and two
1.185m Nogs. Nail studs to each end of Plates. Nail in re-
maining two studs using 1.185m Nogs to get correct posi-
tion. Position Nogs .883m below Top Plate and nail in
place.
Step 3: End Wall: Select one 4.210m Base Plate (Green), one
4.210m Top Plate (Red), four Studs (Yellow) and three
Nogs. Lay out Plates and one Stud on a flat surface and
nail Stud centrally between Plates. Nail remaining Studs to
Plates using 0.770m Nogs to get the correct position. Posi-
tion Nogs 0.883m below Top Plate and nail in place. Repeat
with second End Frame.
Note: For sheds with the Raised Floor Modification option the studs will be 1.780m long to allow the Wall Sheets to pro-
trude 20mm below the Bottom Plate. Refer to Raised Floor Modification section (Page 15).

Step 4: Stand up Back Wall frame and one End frame
and nail together, using two 75mm nails per join,
top and bottom. Stand remaining Frames up and
nail together. Nail in remaining 0.786m Nogs in
End Walls.
Step 5: Position middle Jack Stud, centrally on End Wall
Top Plates and nail in place. Nail remaining Jack
Studs in. Position middle Ridge Beam to Jack
Stud and skew-nail in place using two 75mm
nails each end. Pre-drilling holes before nailing
will prevent timber from splitting.
Step 6: Place intermediate Roof Beams by using Roofing
Nogs to determine correct position (see fig. 2).
Nail intermediate Roof Beams in place. Nail
70x45mm Roofing Nogs in place (End Wall) and
90x45mm Roofing Nogs in place (Middle).
Step 7: Place Frame in correct position, checking the shed is square and level.
Dynabolt Frame to concrete base as instructed on page 4.
Step 8: Temporarily brace each side and roof, making sure each side is square.
Nail strip bracing to outside of Frame (see page 4), making sure it is tight.
Nail multigrip brackets to each of the four bottom corners (two per cor-
ner). Use 30mm bracket nails supplied.
Note: Condensation can form on the underside of cladding. If building paper is required, fit now. The building paper
will need to be supported by netting or roofing twine.

MK4C WALL CLADDING
TO AVIOD CORROSION:
 Where at all possible try not to trap metal filings between two sheets. Remove all metal filings before riveting.
 Carbon in pencils reacts with the Zinc/Aluminium coating on steel. Use ink to mark steel.
TERMS EXPLANATION
 To Tack: To Tack on a wall sheet means to use minimum nails hammered partly in to hold Wall Sheets in position. Should
a Wall Sheet need to be re-positioned, the nails can easily be prized out.
 If a window is required, identify Wall Sheet(s) with window hole pre-cut. Lean up Wall Sheets where window(s) are to be located.
Note:
When fitting Gable
End Sheets en-
sure they overlap
correctly (fig 1).
The overlap direc-
tion may differ
from cladding de-
tail.

Step 2: Back Wall: Position the first Wall Sheet with
the LIP on the right hand side. Ensuring the LIP
is flush with the side of the Stud and the top of
the Wall Sheet is flush with the top of the Top
Plate, tack in place. Position the next Wall
Sheet with the LIP on the right hand side. Over-
lap as shown in fig.1 (page 7). Ensuring Wall
Sheet is flush with top of Top Plate, tack in
place. Repeat with remaining sheets.
Step 4: Nailing Off: Nail one 30mm Clout each side of the Rib (two per Pan) into the Top Plates and Bottom
Plates. Nail Wall Sheets to mid wall Nogs (one per pan). Nail each corner Wall Sheet to Studs using two
30mm Clouts evenly spaced.
Gable Ends: When nailing Gable Wall Sheets to the Top Plate, use a String Line. At the top of the gable nail two
30mm Clouts into the end of each Ridge Beam. This will stop it from twisting.
Step 3: End Walls: Lean Gable Wall Sheets against
the shed to form gable shape. With the LIP
flush with side of Stud tack in place ensuring
the bottom of the Wall Sheet is 10mm above
the bottom of the Bottom Plate. Tack on re-
maining Wall Sheets. Repeat with other gable
end. If fitting a window, nail in Window Studs
and Nog now. Refer to Window instructions.

from the centre on both sides. Fit remaining
Roof Sheets.
Step 3: Centralize Roof at the other end and nail
through pan into Ridge Beam and Top
Plates. Ensure Ridge Beam is straight, then
nail one 40mm Weatherseal into Ridge Beam
beside each overlap (one nail per sheet per
beam). At the back, set up a String Line in
centre of Top Plate. Ensure Top Plate is
straight and nail off, using one 40mm Weath-
erseal per Pan. Repeat at the front.
LIP
Step 2: Starting from the left hand end, centralise
Roof on Ridge Beam. Ensure Roof is tight
against end Wall Sheets and nail one 40mm
Weatherseal through Lip into the Ridge
Beam. At the back, line up Ribs on the Roof
Sheet with the Ribs on Wall Sheet. Using
one 40mm Weatherseal, nail through Lip into
Top Plate. Repeat at the front.

MK4C CLEAR ROOF PANEL (Optional)
Step 1: Leave a gap where the Clear Panel is to be fitted. Position the next Roof Sheet. Ensure it overlaps correctly, then
rivet together, one rivet in the centre and one approximately 600 mm down from the centre on both sides. Rit re-
maining Roof Sheets, overlapping and riveting as you go. Nail on first Roof Sheet (refer step 3 on page 11).
Step 2: Where the Clear Roof Panel is to be positioned, nail a 45x45mm Bevelled Edge Support on each side of the

and overlaps the other. The Clear Roof Panel OVERLAPS both Roof Sheets. Ensure sheet joins are flush at the
outside edge then rivet flat sheets to pressed sheets, three rivets per join. Centralise Roof at the other end and
nail in place.
Step 4: Ensure Ridge Beam is straight, then nail the Clear Panel and Flat Roof Sheet (or second Clear Panel) to
45x45mm Bevelled Edge Supports using one 30mm Clout per Pan. Run two generous beads of Silicone on the
under side of the Pressed Capping Sheet. Position Pressed Capping Sheet on Ridge Beam and nail in place us-
ing three 40mm Weatherseals. Nail one 40mm Weatherseal into Ridge Beam beside each overlap (one nail per
sheet).
Step 5: At the Back set up a String line in the centre of the Top Plate. Ensure Top Plate is straight and nail off, one 40mm

MK4C DOORS
Step 2: Position right hand Door Track (D107) on front wall
up against underside of Roof, with left hand end
hard against the Centre Door Stop. Pre-drill hole in
centre and rivet in place. Remove ALL drill filings
Step 3: Hang right hand door in Door Track. At the right
hand end of Door Track, adjust up or down so that
the Door hangs parallel with shed. Fit one rivet at
right hand end to hold in place.
Step 4: Position left hand Door Track (C107). Follow Steps 2 and
3 to hang left hand Door. Where Door Tracks meet in the
centre, adjust up and down so that the Doors fit snuggly
together, then rivet in place. Remove Doors. Pre-drill
holes into each Rib and at similar spacings into Overdoor
Flashing. At approximately 1/3 in from each end of Door
Tracks put a 50mm nail. Rivet rest of holes.
Step 1: Top Door Tracks: Mark the centre of the doorway on
the Overdoor Flashing. Position Centre Door Stop on
the front face of the Overdoor Flashing and up against

D102) together with three rivets at top overlap. Po-
sition Barge Flashings on gable ends. Slide one
Spouting (D103) inside another until it measures the
correct length. Rivet together with four rivets. Re-
peat with the other Spouting. Position Spouting on
the shed and rivet to barge Flashing at each end.
Repeat with other Spouting.
Step 2: Centralise Barge Flashing on gable end
and rivet in place, one rivet into every
second Rib. Fit two rivets through top of
Barge into Rib. Repeat with other Barge
Flashing. Check Spoutings are straight,
then rivet to Roof one rivet every second
Rib.
Step 3: On the back of the left hand door,

MK4C HASP & STAPLE
Using seven rivets, attach hasp to
Left Hand Door and the staple to the
Right Hand Door as shown.
RAISED FLOOR MODIFICATION
For sheds being placed on a purpose built floor,
(concrete, cobbles, ply etc.), the Wall Sheets will pro-
trude 20mm below the Base Plate. This will stop water
flowing in between the Base Plate and Floor.
The Floor should be made 15mm smaller than Base
Size.
Note: Although it is not essential, fitting Damp Proof
Course in between the Base Plate and the Floor
will give added protection against moisture.
CLEAN UP
 Remove all swarf (drill filings) with a soft brush or rag.
 Hose down roof and walls thoroughly.
 For Coloursteel sheds use touch-up paint provided on all nail heads, rivets and exposed cuts.
