Shed – eye for detail.

Sheds come in different types

The majority of sheds sold today in Australia are of the portal frame design and the components are what is called cold rollformed. But there are two other important types of shed construction that is becoming more popular, the structural steel frame and the stud frame sheds. This is a quick rundown on the three different types:

 

1. Cold rollformed portal frame shed.

This is the most common type of shed and is normally supplied pre-engineered and in a kit form. The main structure (called the portal frame) consists of rolled purlins, girts, batton, top hat and brackets. The cladding and flashings are common to all types.

As you can see the basic prinicple is that all the purlins (both rafters and colums) consist of cold rolled C section joined by fabricated brackets that bolt each assembly together. The roof and wall members are added once all the portal frames have been stood. This is a very efficient system that can be transported easily and assembled on site with minimal tools. 

 

2. Structural fabricated steel shed.

 Nearly the same engineering prinicple as number 1 – except all the colums and rafters are from hot rolled section such as H section, I beam, or C channels with welded cleats and joiners on all ends. All other components are normally the same. The advantage of this type of design is for larger spans especially used in large warehouse constructions and normally over 18 meter width.
Structural steel is a bolt together design with heavy structural steel

The structural steel is heavy to transport but does allow faster erection and extremely high strength joining system. All the other components are very similar.

 

3. Steel stud framed sheds.

 Now this is completely different to the above two. It is identical to the steel stud framing used in housing and results in a very strong overall construction. The walls and trusses are all prefabicated in sections and simply stood on site and then clad. The advantage of this system is the ease of which you finish the sheeting internally and is the reason it is gaining popularity. 

Steel stud frame shed

As you can see there are no colums protruding into the interior and all window and door penetrations are done at fabrication stage. While slightly more to transport – the erection time is greatly reduced and the finish (interior) allows much cheaper cladding solutions. It can be treated in the same way as a normal house frame. 

 

Not all sheds are the same, and to ensure you obtain one that suits your purpose contact Shedeye.

Shed Fire Safety!

Posted on : October 27, 2011

Shed and Garage Fire Safety

Number 0001 of the Shedeye Science Series.

All garden sheds, domestics sheds and garages are a potential fire hazard – not from the shed itself – but from the behaviour of the owners and what they store inside the structure. Currently there are no rules in relation to alarms or safety procedures for sheds and garages. All Australia States have useful information on fire safety in Class 10A buildings as shown below for each state:

Just about every shed or garage (whatever variety) in Australia is utilised for storage from household furniture, cars, workshops, garden equipment & chemicals, pool chemicals, motor bikes, electric machinery, gas, fuels & oils, paint and junk. A great many of these items are highly flamable and hard to extinguish when ignited. This list is only small and some of the above combinations of the items above can be very dangerous. It is wise to consult with the above websites on the dangers of these various combinations. The Queensland Fire website has a specialised Shed Fire Safety report that could be extremely valuable to all shed owners in Australia. If in doubt call your local Fire Brigade if you are unsure of any of these instructions given in the report. Rural sheds have a different set of rules regarding fire safety and the above websites should be able to assist in this area.

Below is a photo of a double garage steel shed that resulted in costly damage to property, motor vehicles and a costly visit by the local fire brigade. Along with insurance claims and the lengthy time period for replacement – there is also the very high risk of injury or death to people. The causes of all shed fires have to investigated by the fire department to provide data for insurance claims and statistics.

The Results of fire in a double garage!

The Queensland statistics for Fire Safety Measures conducted in 2008 are below.

Fire safety measures

Of the 1,589,354 Queensland households an estimated:

  • · 97.3% (1,547,001) has smoke alarms;
  • · 93.5% (1,485,847) has a safety switch or circuit breaker;
  • · 78.6% (1,249,457) removes external fuel sources from around their home;
  • · 51.8% (822,561) has a home fire evacuation plan;
  • · 44.1% (700,487) has a non-mains external water supply;
  • · 42.4% (674,103) has a fire extinguisher;
  • · 31.5% (500,398) has a fire blanket;
  • · 9.9% (156,829) have a bushfire survival plan; and
  • · 2.7% (43,218) has a fire sprinkler system.

But how many have applied these concerns to your garage or shed? How many sheds have fire alarms installed, and how many are fitted with fire extinguishers. These two items should be compulsory for the backyard shed in Australia. There are roughly 10,000 house fires per year, causing more than 1,500 injuries and 70 deaths. Currently there are no statistics for shed fires only in Australia but a search of shed fires on Google will result in many hits.

The problem with sheds being utilised as living space is not only illegal, but does not comply with BCA Class 1 building regulations and hence a very high risk fire hazard. Power connection to a shed also requires a Licensed Electrician for all electrical work in the shed. Extension leads providing power and lighting to the shed are highly dangerous and illegal. All electrical installations must comply with Australian Standards and the BCA as well as being completed by a licensed electrician.

Safety in our domestic garage or shed is important and these items above should be discussed during your investigation or quoting stage from a shed reseller. The cost of smoke alarms and fire extinguishers is very small in relation to the overall shed cost.

Do a quick check on your shed – before it too late. Make sure you check out the relevant fire services in your state for safety procedures and regulations. Workplaces in Australia required Material Saftey Data Sheets on all chemicals, liquids etc not only for fire harzard reasons but for poison dangers also. We ask employers to provide this for the saftey of all employees – yet don’t apply the same rules to family and friends. The number of shed fires have increased recently in the news and endangers life and property.

The number of posts in the Shed Forum on this topic highlights the number of sheds have been burnt down in the last year.

ShedSafe – An Industry Body or A Brand – Part 2?

Posted on : September 28, 2011

Shedsafe errors in the requirements of its members?

This Part 2 (of many to come) is basically regarding the accreditation requirements placed on its manufacturers of sheds that are Shedsafe Accredited. The first requirement that is outlined below is in regard to the thickness of the steel roofing utilised in shed construction. Prior to delving into this area – a brief explanation of the product flow is required of the steel used in the shed roof cladding .

The steel manufacturers process iron ore in a furnace to produce steel – very basic and this is then transformed into the many steel products available on the market. The roof sheet steel is in a coil approximately 940mm wide with a BMT (Base Metal Thickness) of 0.42mm which can have a Coloured paint coating or Zinc Aluminium Alloy. This coil is sold to the metal rollformers to run through a rollforming machine to get the required profile of roofing. These companies also rollform the purlins, battens, tophat, gutters, ridge cap, fascia, barge mould, gable roll and fold most of the required metal flashings. These are all rolled from an order from the shed manufacturer according to the shed being supplied. In some cases the shed reseller may be part of a large group and simply order direct from the parent rollformer.

So the rolled coloured corrugated roofing arrives on site (and all other parts) as a direct result from the customer shed order that has been designed, approved, manufactured, delivered and ready for erection. Your shed is also issued with a 15 year roofing, cladding and purlin warranty from the steel manufacturer also sometimes the parent company of the shed reseller.

Lets start with the quote to the customer from the shed reseller. You’ve given all the details of your requirements of a shed and accepted the quote. Here is a small sample of one such Shedsafe Accredited reseller that is also owned by a national Shedsafe Accredited Shed manufacturer.

 

Details of Roof Sheet Thickness

 

Notice the roof cladding is 0.40 TCT Trimdek Profile C/B. The Trimdek and Colorbond description is fine, the 0.40 TCT is the roof sheet properties – that is in this case a 0.40mm thick Total Coated Thickness or back to the earlier description is equivalent of 0.35mm BMT (Base Metal Thickness). So this is 0.07mm thinner than the normal roof sheeting that should be installed on a domestic sheds. Why do they supply this sheeting for roof materials on sheds? Because it’s cheaper and many people don’t know the difference! So Shedsafe accredited resellers and manufacturers have been through the extensive training and requirements of the ASI run Shedsafe group. In fact in one of their requirements of shed manufacturers to become accredited is the fact outlined above regarding product warranty for 15 years. Here is the item by Shedsafe that requires manufacturers and resellers to:

 

15 Year Roofing Warranty

 

So the Shed Industry Benchmark group of Shedsafe – is setting the target or requirement of a 15 year warranty and its strick accreditation process is followed by all of its members. So the sample above (a shed which was supplied in 0.35BMT roofing) will have a 15 year warranty? WRONG.

Now lets look at Shedsafe again, an industry body run by the ASI of which BlueScope is the major sponsor. BlueScope also manufacturers the steel coloured coil for these very same Shedsafe accredited manufacturers and resellers. So lets examine the warranty for 0.35BMT roofing use in sheds.

 

 

BlueScope Roofing & Cladding Warranty

 

The main part in this warranty is that the supplier of the steel will not give a warranty on the 0.35BMT roofing that can be found in part 1 of the terms and conditions of the BlueScope Shed & Garage Warranty.  The basic error is that the BlueScope run ASI and its ShedSafe group have not covered all the small detail and continues to stipulate that Shedsafe accreditation is the Industry Benchmark. If they cannot enforce a simple base metal thickness that the manufacturer stipulates – what else is also wrong?

If your shed is supplied with 0.35BMT (or 0.40TCT) roofing – then it is not covered by the BlueScope warranty and the shed reseller will have to provide an independent cover for this warranty. Will they provide a 15 Year warranty on a 0.35 BMT thick roof sheet?
Accreditation is a simple word that enforces the meaning of having all the checks and processes in place to eliminate error.
This is one error that Shedsafe has to correct.
Next week part 3 – more detail of the marketing group Shedsafe!

Sheds – What happens with Carbon Tax or the ETS implementation?

Posted on : March 5, 2011

The home or domestic garage or shed has become an icon in the Australian backyard. Whether it is a normal 6 X 6 double door garage or a 3 x 9 storage shed – this industry will be affected by every single company involved in the manufacture of all the components of this iconic “SHED”.

So who are these companies that need to charge you more as a result of the Carbon Tax? They happen to be the biggest emitters of CO2 in Australia because we mine minerals (including coal etc) to manufacture simple things such as steel, aluminium, glass, cement, paint, timber (YES – these guys do emit CO2 to cut timber), carpet, plastic downpipes, electrical wiring, and the list is endless. All of these companies will have to increase prices in order to pay for the Carbon tax – and the answer is that you & I will pay. There is no alternative or secret formula in the production of steel for example – the operational side of steel producers are at the apex in efficiency in the world as far as CO2 emissions are concerned. Australian giant BlueScope and One Steel have the most efficient steel making plants in the World – so what happens when a Tax is added to the industry? The basic recipe for steel making is complex – yet simple in the chemical conversion – Iron Ore is represented by Fe the symbol the same as C represents Carbon – Oxygen is represented by the symbol O – and the process of steel making (Plus energy – coal furnaces) is as follows:

Iron Ore is represented by the symbol – FeO – (One atom of Iron plus one atom of Oxygen) and Carbon Monoxide is represented by CO – (one atom of carbon plus one atom of Oxygen) – this is chemistry and the conversion is represented by the following formula.

FeO + CO = Fe +  CO2 – all the numbers on both sides add up – but it is the heat required by burning coal or fuel to complete this process that the Carbon Tax will be implemented on. Because it takes 2 tonne of CO2 to make 1** Tonne of steel – the price will increase by exactly the Carbon Tax per tonne at the source. But – it doesn’t stop there – it needs to be rollformed, transported and erected. Don’t expect any change out of 16% to 30% per tonne at the end site and this is a conservative figure. Science currently does not have the answers to improve the process to reduce the CO2 emissions greatly – and the BlueScope website has plenty of information on exactly what has been discussed above. The end result is that it will be cheaper to import steel (finished product) along with all other building materials like Aluminium, cement, glass etc from countries (like China) that have no Carbon Tax.

This tax directly on manufacturing industries will be a major setback for the shed industry if they cannot afford to pay this tax – by either adaption or economically – to compete with imports. The result will be no more Australian Made – developed and innovated by Aussie industry – last but not least – a very sorry and diminished Shed Industry.

So if your shed is approximately 12 tonne of steel, concrete, plastic, glass, etc (the average weight of a 6 x 6 garage shed) – then why can’t you get a credit against this tax if you grow plants or store timber over the next five years (or whatever is deemed acceptable) to offset the emissions of the 29 to 40 tonnes of CO2 that has been released to the atmosphere to manufacture this shed.  For example a gum tree that has a height of 30 meters and a diameter of 800 millimetres and is three years old will have stored nearly 5.885 tonnes of CO2. In this case your shed would be paid for in carbon tax in 8 years approximately. It is the environment we are talking about – not CO2.

 

**Steel making requires a high heat – the furnace – they need CO for the conversion to molten Iron (the CO comes from the coal or furnace fuel) so less than one tonne is used in the conversion and the other plus tonne is used in the heat  = 2 tonnes. The price of carbon dioxide (not carbon) to make one tonne of steel – hence the carbon tax

Carbon Tax to Send Shed Prices Sky High

Posted on : March 1, 2011

Shed Photo compliments of Alibaba LTD

How do you think the shed industry will be after you study the ramifications below?

What will be the implications on shed prices of the current governments carbon tax of approximately $20 per tonne of carbon dioxide along the supply chain of manufacturing, delivering and erecting a shed on your property. Just to explain carbon tax simply – is if you look at your electricity bill – it will show how many tonnes of CO2 you have put into the atmosphere simply by living and doing the normal things everyday. Approximately 4 tonnes of CO2 is expelled into the air if your bill is around $500.00 per quarter.

To manufacture, process, deliver and erect your shed is also putting this CO2 into the atmosphere and will be calculated accordingly, adding to shed or garage prices. The basic principles of economics will apply to all industry, transport, offices etc, so in dollar terms, you will be hit with an additional Carbon Tax amount relative to the location, power usage in all areas and the construction of your shed.

Indicators so far are expecting in manufacture and transport of 16% increase plus the additional charges the shed resellers, manufacturers, transport companies and administration will charge to cover these costs anywhere up to 20% increase in shed prices . BIG, BIG BIG and will get bigger – but don’t worry it will be on everything from roast lamb, fuel, holidays, restaurants, etc etc. Shed and Garage prices are not alone and if you are looking to save money – purchase your shed (and everything else) before the introduction of Carbon Tax but if you want to stop CO2 entering the atmosphere you must wait for the introduction of Carbon Tax!!!!!!

Will this make substitutes such as wood and brick more price competitive?  Are steel price rises in conjunction with the carbon tax going to make shed prices too expensive for the backyard shed?

Is your shed a Class 1 or Class 10a Building?

Posted on : February 25, 2011

Class 10a and Class 1 Buildings

According to the BCA (Building Code of Australia) a Class 10a building Is defined as a non-habitable building being a private garage, carport, shed, or the like.

While the BCA defines a Class 1 as one or more buildings, which in association constitute—

(a) Class 1a — a single dwelling being—
(i) a detached house; or
(ii) one of a group of two or more attached dwellings, each being a building, separated by a fireresisting
wall, including a row house, terrace house, town house or villa unit;
or
(b) Class 1b — a boarding house, guest house, hostel or the like—
(i) with a total area of all floors not exceeding 300 m2 measured over the enclosing walls of the
Class 1b building; and
(ii) in which not more than 12 persons would ordinarily be resident,

When we are talking sheds, it is almost always the distinction between a Class 10a and Class 1a that cause confusion as Class 1b is unlikely to be a shed!

This makes the classification quite a simple task and it is all in the definition of Habitable and Non-Habitable rooms.

Class 1a building

If you have a room in your shed (even if the shed contains only a single room) that contains any of

  • Bedroom
  • Living Room
  • Lounge Room
  • Music Room
  • Television Room
  • Kitchen
  • Dining Room
  • Sewing Room
  • Study
  • Playroom
  • Family Room
  • Sun Room

Then you have a Class 1a building.

Class 10a building

And if all of your rooms in your shed contain only

  • Bathroom
  • Laundry
  • Water closet
  • Pantry
  • Walk-in robe
  • Corridor
  • Hallway
  • Lobby
  • Photographic darkroom
  • Clothes-drying room

Then you have a Class 10a building.

The only tricky bit

The only ambiguity left in the BCA definition of Habitable and Non-Habitable is the statement that rooms or “Spaces that are not occupied frequently or for extended periods” are Non-Habitable.
So what are items like a Cinema or theatre room defined as?  The are defined a Habitable under this definition (take a look at this advisory notice from the SA Government).

Why is this even important?  From a paperwork and regulation perspective it is far easier for Class 10a buildings!

Man’s garage too short!

Posted on : February 14, 2011

This article in the Herald Sun just goes to show how important it is to do your own measurements and explain to your distributor what you are putting in your garage or shed, otherwise you may end up in a legal battle!

Man sues for short garage – Herald Sun

While this was an off the plan brick garage, there are many cases when the Roller Door Clearance and length of steel kit sheds have been incorrect, causing hassle for both the distributor and the customer. The Garage is useless if you can’t fit in your cars or Caravan and access your storage and workspace areas!

If you are going to put two cars in your garage, then make sure you measure them, or look at the car specification sheet for your make and model. A standard Holden Commodore (VE) model is approximately 4.9 meters long and 1.8 meters wide. If you wanted to put two of these in your garage and pack them like sardines, end to end, you would need slightly over 10 meters in shed length, however you also have to allow for lost space inside the shed due to the frame.

In reality, you really would not go less than 12 meters as this would give you a little bit of additional room at a low shed price increase (providing you are not increasing the gable end of the shed, an extra meter can add quite a bit of cost depending on how wide your shed already is).   The extra two meters allows for the frame inside the garage, some room at each end of the shed and some room between your cars, this is if you have the space, of course!

You also need to consider if you want space for a workshop at the side or end of the shed, or storage room.  If so, an allowance must be made, not just for your workshop or extra storage room but also to allow you access to the space itself.

So if you want to use your new Shed or Garage to put in your 4WD, your caravan, your truck or your Hum-Vee, make sure you measure and then give yourself some additional room to get in and out of the motor vehicles.

The case above is not as rare as it should be.

Steel Shed Price Rise – Buy NOW!

Posted on : December 16, 2010

Hold on, read this before you make that decision.

Unlike the previous hefty price rise (September 2010), this price rise (January 2011) is approximately 5% and is limited to colorbond products only, the main product being the cladding, not the frame.  There have been roughly 3 price rises per year over the last couple of years, and until Iron-ore prices stabilise, shed prices likely to rise over the next 24 months.  Shed Prices should stop rising with a great deal of additional ore capacity coming on line, however it is also dependent world demand staying constant.

For a standard 6 meters wide * 6 meters long * 2.4 high you are talking of a price increase of less than a hundred dollars. You should be able to negotiate a discount to cover this amount if you wish to buy after January.

The price of steel sheds is still far more economical than substitute products, and if global demand does not increase further, the continual price rises should taper out.
