Fortress TUF400 Garden Shed
The Duratuf Fortress 400 is one of the most popular garden sheds on the market featuring an internal timber framing for added strength, ease of assembly and also makes hanging tools a breeze!
The Tuf 400 is one of our most popular garden sheds and is a generous size for storing the mower, wheelbarrow and tools or can also be used as a pump shed.
Getting To Know The TUF400
We offer an array of colour options with 9 to choose from for our Fortress Range.
If you would like to have a combination of two colours, for example Lichen walls with
Karaka roof and door, choose any two colours from the selection above.
Full Timber Frame
A machine-finished timber frame forms the backbone of our garden sheds. The timber gives added rigidity and strength and is interlocked at the corners to form an extremely robust structure.
Traditionally sheds have relied on nuts, bolts and screws to hold them together. Duratuf Fortress sheds however are constructed with the cladding fixed securely to the frame using galvanised nails - just like a garage. This braces the structure and gives the added strength needed to last that extra distance.
Duratuf Fortress garden sheds feature unique full-size wall sheets that wrap around the corners (Fig. 7), eliminating any corner joins. This gives the shed amazing waterproofing qualities and is clearly superior to most conventional corner designs (Fig. 8)
Wrap around corners also provides exceptional bracing strength and eliminates any sharp edges.
Wrap Around Roof
The roof design on the Fortress range also features pre-folded roof sheets that wrap over the end walls to create a watertight finish. This makes installation easy and ensures that there are no leaks.
Advanced Water Run Off
Surely everybody wants a weatherproof garden shed? It’s important then, that water flows away from your shed to ensure your valuable gear is kept dry. The unique design of our sheds ensures that water is not trapped on or around them.
Duratuf timber frame sheds feature a unique construction method where the cladding is nailed to the top and bottom plates. This method ensures that water runs away from the shed easily as there are no channels to trap leaves, dirt and water that will leak, or sit and corrode the cladding. (Fig. 1)
Conventional shed designs require a channel at the top and bottom of the shed to hold the cladding together. (Fig. 2)
Fortress kitsets can be modified to allow the wall cladding to extend past the base of the shed when placing on a raised concrete floor. This completely eliminates the possibility of water running back into the base of your shed.
0.4mm Hi-Tensile Cladding
Duratuf Fortress garden sheds are manufactured from strong hi-tensile .40 gauge steel, roll formed into an attractive 6-rib profile and are available in a Zinc / Aluminium finish or in a range of popular colour coated options. And because we are so confident in the quality of our cladding, we back it up with a full 30 year warranty (conditions apply).
Superior NZ Made Quality
When you invest in a Duratuf garden shed, you are investing in a New Zealand made quality product that you can rely on.
Manufactured on home turf means that the product is suited to New Zealand conditions. Further to that, only the best materials are used, from NZ grown timber through to premium hi-tensile steel and quality fastenings.
Keeping Kiwis in jobs plays an important role in our community and gives the added assurance of controlled quality
during manufacture, coupled with a locally backed warranty - we’ll be here if you need us!
Custom Build options
Need something special? Something a little bit out of the ordinary? Allow us to create the perfect garden shed for you. Being a 100% New Zealand owned and operated company, we can modify your shed to suit your needs.
Solid Timber Floor Kit
Duratuf Timber floor kits create a strong, level working platform that fit inside the shed and on top of the bottom plate, not underneath like other garden sheds. This has a number of advantages.
• It creates a level access into the shed.
• The cladding extends past the floor level and stops water leaking back into the shed.
• The extra weight inside the shed provides exceptional hold-down ability.
The kit includes everything that you need including thick gauge timber floor boards, ground treated H4 joists, galvanised nails and an attractive doorway flashing.
Raised Floor Modification
The unique design of Duratuf timber frame garden sheds allows them to be adapted using the Raised Floor Modification. This makes the cladding protrude 20mm below the base plate. Any water running down the wall cannot flow into the shed ensuring a dry, weather-tight floor.
If building a raised concrete pad for your Fortress garden shed you do not need to order the Raised Floor Modification as this can simply be done when assembling the shed.
Building A Concrete Floor Base
Step 1 - Establish the size of the shed and excavate a sufficient area. Remember to allow for a rear roof overhang of 80mm and 30mm for end walls.
Step 2 - Ensure that the base substrate is compacted firmly. We suggest that the slab should be 80mm thick in the middle and 100mm thick around the edges (Fig 2).
Step 3 - Lay boxing to the required size. The raised slab size should be 15mm smaller than the overall base size of the shed and at least 30mm above the ground line. See Fig. 1
Step 4 - Lay plastic sheeting if required. Plastic sheeting under-slab will prevent moisture from coming through from underneath.
Step 5 - Pour concrete and screed flush.
Extra Wall Height
All Fortress garden sheds feature a generous 1.9m wall height as standard, however there are times when a little extra head height can come in handy. Now you can have the option of 200mm extra wall height!
If you feel that a little extra head height would be a luxurious advantage, Fortress sheds can now be modified easily to give you that extra height you need. This not only creates a feeling of spaciousness, but gives more room for taller people to move around freely. It also gives more capacity to hang tools or shelving, and to maximise storage of tall objects.
The increased Head Height Option is also ideal in a workshop situation, allowing more room to move when working at a workbench, as well as providing some added space to install lighting. Surcharge applies.
Duratuf Fortress garden sheds are delivered in a compact carton which includes all timber and steel components, including the hardware.
The Tuf600 and Tuf800 require a separate timber pack as well.
Raised Floor Modification
The unique design of all Duratuf sheds allow them to be easily modified for use with a raised concrete pad.
The modification causes the wall cladding to overhang the concrete floor slab, which creates excellent weather-proofing, something that can't be done with non-timber framed garden sheds.

For gable shed models you can choose from either single side or both sides of the roof. Please note that clear roof panels may condensate more than a steel roof during cold weather.
Door Security Upgrades
Keep intruders at bay by upgrading your shed doors to keyed locking handles. These are not only more secure, but also easier to open with one hand if you are holding an armful of gear as you enter.
Bolt Down Kit
If your shed is to be attached to a concrete floor or base, the Bolt Down Kit allows you to securely anchor your shed without damaging either your concrete pad or the timber frame of the shed. The kit consists of hot dipped galvanised steel brackets, with Dynabolts to anchor into the concrete floor and screws to attach to the bottom frame.
Peg Down Kit
The Duratuf peg down kit is perfect for anchoring your garden shed on ground such as grass, dirt or metal. The 6 x H5 treated pegs are driven into the ground and screwed to the bottom plate with the stainless steel screws provided. A timber floor kit can then be fitted over the top if required.
