The main aim is to generate discussion to educate and learn from the current regulations concerning LHL Standard Cyclic Test Method for Cyclonic Areas. From April 2009 all cladding and batten manufacturers need to demonstrate that their metal roofing assemblies specified for cyclonic areas of Australia have been tested using the LHL test method. So to understand the basic test of the roof assembly – each manufacturer must get their roof sheeting (all profiles specified for cyclonic regions) tested under LHL. By stipulating that the company brand of corrugated has to be LHL tested, they are accepting that all the corrugated rollformers held by that company are identical. From a roll former’s point of view, if it can be demonstrated that structural roll formed products with the same girth and BMT thickness such as roof sheeting and top span that is identical in profile, and manufactured from the same coils of origin that have undergone the LHL testing criteria, what is the real purpose of having the product tested while there remains a question regarding the safety of the total structure?
It is in the real world where actual wind tunnels exist, moreover, regardless of whether the product has been endorsed by shedsafe, structures will continue to fail even before completion. A Building inspector was recently surprised to notice that a garden shed structure was actually made from a .75 mm stud frame with 12mm tie downs at each stud, along with two extra 12mm tie down’s at each corner. When the customer advised the supplier, who in turn asked the building inspector to explain the problem, the building inspector advised the supplier to read the literature provided by the ASI’s shedsafe endorsement. Getting back to the manufacturer’s point of view, there is clear evidence that the only guarantee and endorsement of ShedSafe may offer is the customer will have no idea of the origin of the actual material used to manufacture the product or if the product has been tested. Therefore if the structure is endorsed by an incompetent engineer who has compromised his or her ethical standards, nevertheless signs a FORM 15, there will be no recourse unless the company that has hired the engineer replaces the product.
Besides this, as already pointed out, if one single LHL endorsement can be used as a blanket cover for an entire corporation regardless of the corporation’s many separate roll forming outlets with differing profiles, or whether the origin of the coil is Australian or Imported, how does the building inspector know the difference without authentic documentation? Many thanks to the contributions of the rollformer and the shed manufacturer for this valuable insight into only two areas of the industry. This Part 2 (of many to come) is basically regarding the accreditation requirements placed on its manufacturers of sheds that are Shedsafe Accredited.
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. 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. 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.
Now lets look at Shedsafe again, an industry body run by the ASI of which BlueScope is the major sponsor. Accreditation is a simple word that enforces the meaning of having all the checks and processes in place to eliminate error.
No it was prepared by Joint Technical Committee BD-006 and was approved on behalf of the Council of Standards Australia on 23 November 2010 (published on 30 March 2011). To further increase the money revenue potential, ShedSafe charges around the $500.00 mark to each of the shed sellers or distributors. They think it is a necessity as if your competitor has it then you will loose sales as the consumer is being mislead.
This is a look at the Industry Body called ShedSafe and will raise many eyebrows in the shed industry through the dominance of its name.
Lets go through some of the ShedSafe details advertised to the customer and also to prospective shed suppliers. This is on the literature to shed suppliers – so make no mistake as to the marketing intentions of this statement!
Not much promised to the customer who buys a shed except that the shed you have purchased is ShedSafe accredited. Now this is an important concept – as all factors quoted must be performed by a licenced builder or a building certifier. For non shed readers, steel manufacturers create hot rolled steel, for sheds they then create cold rolled steel that is consumed by rollformers to create the portal frame for your shed. At each of these stages there is a chance that steel is imported, the rollforming for custom designed sheds is usually done in Australia as the volume of the kit reduces the economics of importing, the lack of economies of standard colour and sizes and the delivery network make it more economical to do in australia.
To explain the above further – the cold rolling part of the manufacture process starts off initially as cold, but as the material is rolled it is reduced in thickness and also gains heat.
If this is too much for you to digest with your morning coffee, then all you need to focus on is the R value. The R values of the same roof or wall vary between summer and winter – depending on which way the heat is travelling.
Follow these steps to work out your minimum R value and how to select an appropriate insulation. Step 2 : Work out the minimum R value for your roof and wall based on BCA minimum R values. For a far more through and detailed analysis please read  Insulation requirements for Class 10a buildings.
Don’t be overwhelmed by the complexity of this flow chart, if you follow it step by step it is relatively straight forward! All in all the SEPP is a massive improvement and goes a long way to helping to improve the inconsistencies between councils in Australia.

The current requirements of reflectivity standards of metal cladding as seen in BASIX, BCA and SEPP all seem too ambiguous for correct applications and on site judgement and analysis.
The standard by each authority vary and will cause some problems within the industry along with questions for the Building Certifier during the approval process.
Why is there a contradiction among something on coloured steel cladding when each colour has its own Solar Absorption Index Value? As this spreadsheet describes the colours taken from the BlueScope website and lists four factors that are currently used in the building industry. The BASIX scale is based on the following and is linked directly to the value of solar absorption index.
BCA has classified roof colour also on the basis of their solar absorptance, and referred simply as light, very light and dark.
Compliant and exempt developments will be determined by the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008, for all local councils from the 1 September 2011.
This a great piece of legislation, as any move to create consistency at the state or federal level is a brilliant initiative in Shedeye’s view!


Can the regular human navigate this code easily, if you have a few hours to invest and have nothing better to read, then yes it is quite clear, with a few ambiguities thrown in for good measure. There are a few surprises thrown in, for example a shed (not a carport) for any other purpose than a cabana, garden shed or a gazebo cannot be classified as an exempt development. Shedeye has attempted to simplify the legislation around exempt Garden shed developments, not sure if we have, by creating a hopefully easy to follow flow chart.
There is still some ambiguity in some of the legislations, for example what does low reflectivity mean?

It is very important to get the classification of your shed, garage or carport correct (Class 1a or Class 10a) as per the previous article.
Take the following Development Tribunal decision from the Toowoomba City Council as an example of getting the classification wrong. In this case a carport was used as an entertainment pavilion, however the council gave approval as a Class 10a building in the expectation that the structure was to be used as a carport. The new owner’s decided to put in a pool that would block vehicular access to the Class 10a structure. Who was responsible for paying the additional fees to convert the building from a Class 10a to a Class 1a? There are a great many cases where the classification has been made incorrectly and it has caused a great deal time delays, and in some cases cost. Take a look at this article where a building was funded from the federal stimulus program for Black Rock Primary School, it was incorrectly classified as a Class 1oa and it looks like it will have to be moved.
According to the BCA (Building Code of Australia) a Class 10a buildingIs defined as a non-habitable building being a private garage, carport, shed, or the like. 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. The first is with a rollforming perspective, and the second from a shed manufacturing perspective. It was officially phased in on the 30th April 2009 to meet the Building Code of Australia Specification B1.2.
There are numerous testing stations in Australia and the one chosen here for example only is the James Cook University Cyclone Testing Station.
For another company to provide corrugated roof sheets to cyclonic areas – they too have to complete LHL testing. For example, the manufacturer of roll forming materials may argue that while the LHL testing applies only to the roof cladding and “immediate members” that support the roof cladding, failure to include the importance of the connections at the apex, knee, and tie downs, begs the question; how does the manufactured product miraculously become only when the supplier has had the immediate members tested in a wind tunnel that simulates cyclonic conditions? Does the material in question have a specific test certificate stating the origin of the material along with an endorsement from the testing facility given that what he is inspecting explicitly refers to the cladding and top span required on the approved plan, or does he really care about the weightier issues that he may be forced to confront? This occurrence was exploited by others in the shed industry to their advantage by giving this as an example of a non-compliant shed industry member. The first requirement that is outlined below is in regard to the thickness of the steel roofing utilised in shed construction. 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.
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.
So the sample above (a shed which was supplied in 0.35BMT roofing) will have a 15 year warranty? BlueScope also manufacturers the steel coloured coil for these very same Shedsafe accredited manufacturers and resellers. ShedSafe charges the shed suppliers (those that have the software and organise the materials) to have engineers review three of their shed designs. Accreditation is a quality assurance system of all processes that ensure the end product is safe and sound – the Shedsafe system of accreditation does not achieve this.
The presumed importance of a brand called ShedSafe with its accreditation deeming members have an exclusive right to the name is confusing to the consumer in the assumption it is a regulatory body. Join up and you will influence the purchasing decisions of most, if not all consumers shopping for sheds! The steel at this point changes in mechanical property regarding strength etc, and also usually bathed in oil to prevent rusting if exposed to H2O and O2. These variations on the choice of colour may affect the outcome of approval depending on which code is followed and whether or not the local council regulations agree or disagree with these codes. How these play a part in colour choice for metal cladding on these buildings requires an understanding of each of the columns above. This is simply the list of ColorBond Colours, ZINCALUME and Metallic Colours from BlueScope. The Solar Absorption is simply a numerical index that shows the amount of solar “radiation” that is absorbed by that particular colour. SEPP is the body of government in NSW that has legislated the requirements of colour to be used in Class 10a buildings.
BCA has its own version of classification of colours in this list and refers to Very Light (VL), Light (L) and Dark (D). BASIX is the New South Wales Building and Sustainability Index body with its own colour classification and is as follows: Light (L), Medium (M) and Dark (D). Being low reflective can only be Dark on the BCA Scale or Medium and Dark on the BASIX Scale.
The test involves includes the roof assembly including the roof sheets, fasteners and the battens and their support fasteners. Also in this discussion the roof cladding type is corrugated – produced by all of the rollforming companies in Australia and also used in cyclonic regions in Australia. Very far from the truth, the particular shed supplier warned the shed erector constantly regarding construction techniques – all advice was ignored.
Prior to delving into this area – a brief explanation of the product flow is required of the steel used in the shed roof cladding . This coil is sold to the metal rollformers to run through a rollforming machine to get the required profile of roofing.


Here is a small sample of one such Shedsafe Accredited reseller that is also owned by a national Shedsafe Accredited Shed manufacturer. So this is 0.07mm thinner than the normal roof sheeting that should be installed on a domestic sheds. If they cannot enforce a simple base metal thickness that the manufacturer stipulates – what else is also wrong?
Now of course these three designs are not their typical shed, they are over engineered and would be under the meticulous watchful eye of the shed suppliers engineers. It is not such a body as all shed (Class 10A Buildings) constructions are governed by the BCA only. This is marketing and nothing else – the problem is in the wording as follows by one of the accredited suppliers. This cold rolling gives the steel the mechanical properties required depending on the thickness required for end product use. What are solar absorptance, reflectivity, gloss levels, heat transfer calculations, R Values, BASIX Scale, BCA Scale, and visual acceptability?
This is not to be confused with reflectivity and the two are not inversely proportional to each other. The requirement is based on reflectivity and although not exactly stipulated – it only accepts Medium or Dark colours (low reflectivity). For the purpose of this investigation – the BCA scale has been used as this code is generally utilised by all local councils and Building Certifiers. The applicants bought the property on the understanding that the structure could be used as an entertainment pavilion.

The LHL stipulates that for a company to sell corrugated roof sheets in cyclonic areas – it must undergo LHL cyclic testing. Those in the rollform industry know that this is not the case, and apart from some minor variations between machines it is the profile of corrugated (along with the feed coil properties) that determine the strength and its ability to undergo LHL test compliance. In other words, wherever there is an accident on site during construction resulting in person(s) injured or killed, the shed erector, rather than those who endorsed the shedsafe product, will be liable.
Subsequent investigations resulted in the shed manufacturer being involved – but of all the parties involved – the shed manufacturer supplied and erected the shed for no charge. These companies also rollform the purlins, battens, tophat, gutters, ridge cap, fascia, barge mould, gable roll and fold most of the required metal flashings. This does have the potential to pick up glaring errors, but as far as being representative of the typical shed supplied, there is no way!
These coils may also be heated (cold rolled annealed) to make the steel more flexible for folding processes, and the to a coating line to galvanise (coated in zinc) or Zincalume line (zinc-aluminium alloy) with painting (colour) if required. All these factors play a role in the decision of colour choice (or ZINCALUME ®) of your shed metal cladding and roofing.
The problem is not the cut off area – but simply in the statement of “low reflective material”.

The BRAND corrugated roofing is sold by some of the big multinational rollformers throughout Australia.
Yet Company XXX has to undergo LHL testing even though all its machines are identical to Company ZZZ machines.
These are all rolled from an order from the shed manufacturer according to the shed being supplied. Just to confirm all the major brand users of this ShedSafe have similar branding advertisements. Cold rolled steel is then made available in different grades, properties and coating depending on the end usage.

The Company here is Company ZZZ, and to comply it sends it corrugated roof sheeting to the cyclone testing centre to meet compliance to the LHL test. This is the only industry where identical products are testing not the manufacturing process.  The LHL testing should in fact be the responsibility of the rollform machine provider – and most of these (especially Australian and New Zealand machines) would all supply compliant corrugated roofing sheets. In some cases the shed reseller may be part of a large group and simply order direct from the parent rollformer.
So Shedsafe accredited resellers and manufacturers have been through the extensive training and requirements of the ASI run Shedsafe group.

This sample is rollformed on one machine that converts the coil (flat sheet) to corrugated roof sheets. There should be compliance for these rollform machines to be registered to conform to LHL testing. In fact in one of their requirements of shed manufacturers to become accredited is the fact outlined above regarding product warranty for 15 years. Yet Company ZZZ who has gained LHL compliance for its rollform machines can buy a new corrugated rollformer from China that may not meet the standards previously obtained from its original sample material.
