BEFORE YOU START:
• Read all instructions carefully
• Identify all parts and check quantities against parts list
• Select a level site
• Do not mark cladding with pencil as lead can cause corrosion to cladding
• During assembly, ensure all drill filings are removed between layers of steel, before riveting together
SAFETY:
• Do not attempt to build your shed in high winds
• Beware of sharp edges, we recommend that you use gloves
• Protect your eyes and ears
• For ease of assembly, use a friend to help
TOOLS REQUIRED:
WARRANTY REQUIREMENTS:
The following maintenance process needs to be adhered to, to qualify for the steel warranty of your Duratuf Guardian

GUARDIAN WOODEN FLOOR
• The optional Guardian kitset wooden floor is precut and designed
to be fitted into the shed after the shed is assembled.
• Assemble shed as per instructions and fit floor last.
(see page 13 for details).
CONCRETE SLAB FOR RAISED BASE PLATE SHED
To build a raised concrete slab for your shed to sit on, we recom-
mend the following:
• The raised slab size should be 15mm smaller than the base
size of the shed and at least 30mm above ground line.
• The slab should be 80mm thick in the middle and 100mm
thick around the edges.
• The slab should be laid on a solid or compacted base.
• Plastic sheeting under slab will prevent moisture coming
through from underneath.
• During construction, you may raise the bottom timber
plate to allow the wall cladding to protrude 20mm below
the bottom plate. This will stop water flowing between
the bottom plate and the concrete floor.
See note on page 8.

RAISED BASE PLATE OPTION
(For sheds placed on a raised concrete floor)
No doubt by now you will have decided what sort of base you are putting down.
Please read the section that applies to your situation.
If you choose to pour a concrete base you will need to decide whether you wish to raise the base plate of your shed.
This allows the cladding to protrude below the surface of the concrete and ensures a water tight pad.
See concrete pad specifications below
By choosing this option you will need to make the concrete pad to the specification below.

SECURING SHED
Secure your shed using Treated Timber Pegs or a Bolt Down Kit
TIMBER PEGS—WOODEN FLOOR
• The optional Duratuf Timber Peg Down Kit includes six H5 treated timber
pegs that can be hammered into the ground and then attached to the
Base Plate with stainless steel screws. A Guardian timber floor can then
be fitted on top of the Base Plate if required.
BOLT DOWN KIT—CONCRETE
• The optional Duratuf Bolt Down Kit includes 6 x galvanised
brackets, screws and dynabolts.
• Space the brackets evenly around the shed and fix to the Bottom
Plate and the concrete slab. A 10mm masonry drill bit is required.
FITTING A GUARDIAN FLOOR KIT (OPTIONAL)
• Position the Floor Joists centrally between the side
Base Plates and skew nail each end with two 75mm
nails.
• Check that the shed is sitting level and square . Check
that the diagonal Bottom Plate measurements are the
same. This ensures that the shed base is square.
• Place the Floor Boards in position. (You may need to
cut the last Floor Board to the correct width using a
Skill Saw.) Nail each Floor Board in, using two 50mm
nails each end and two nails into each floor joist.
