Recently, a few readers have inquired about an asbestos cement sheeting profile known as . Here’s some pictures and how to identify it. Standard profile corrugated asbestos cement sheeting is like the baby brother of . It’s often found in the construction of old domestic garages and sheds and in addition it can be found on commercial buildings such factories, shops and farm sheds.

In a world where every smartphone seems to come with its own version of Siri, Samsung is finally ready to release its own, fully functioning AI-based virtual assistant. It was used for both wall and roof applications and is fixed on with screws and nails. Fact file: Years of manufacture: Standard profile corrugated asbestos cement sheeting was made from circa 1. Significant Manufacturers: James Hardie & Coy manufactured these type sheets under the trade name of Fibrolite Standard Corrugated Sheets. Wunderlich also manufactured similar sheets with a trade name of Durabestos standard corrugated sheets. Dimensions: Width: 8. Pitch (distance between corrugations): 7. Depth: 2. 5mm (1 inch). Standard Lengths: 1. Corrugations: 1. 1 ridges top side (see picture below). ![]()
Cellulose (asbestos free) equivalents: No cellulose or asbestos free equivalent products were made. This saves a lot of guess work, which often occurs with other types asbestos sheeting’s and modern equivalents (such as Super Six, Hardi. Fence and Hardiflex). It’s asbestos, so take all the usual asbestos precautions when dealing with it. Dangers and safety precautions: These sheets are manufactured from white asbestos (chrysotile) and early sheets may possibly contain blue asbestos (crocidolite) along with cement and silica. Inhalation of asbestos fibres may lead to asbestosis and/or mesothelioma. The usual protective clothing should be worn such as disposable overalls, P2 respirator, gloves and boots. Sheets should be removed intact, avoiding breakage. Sheets should be wrapped in black builders plastic and sealed with duct tape prior to disposal. These sheets can be particularly fragile and if walked on you risk falling through. Not only will you be hurt when you hit the ground but you will receive deep cuts from the broken sheeting as you fall through. Pictures of standard corrugated asbestos sheeting: A domestic garage cladded with standard corrugated asbestos sheeting. This one has a steel frame and wood purlins along with sheet metal door. Popular in the 1. These are used on the roof and sides. Wall and roof. The original product was an asbestos cement product known as Super Six manufactured by James Hardie & Co. Both products look very similar but how do you distinguish between the two? The original corrugated “Super Six” asbestos cement sheets were manufactured by James Hardie & Co. It was widely used as fencing and for roof sheeting with much original Super Six fencing is still in use today. However, from after 1. Super Six was replaced by a similar looking product known as Hardifence. This new product eliminated the deadly asbestos fibres and replaced them with the much friendlier and safer cellulose fibre, which is essentially made from wood pulp. Hardifence is still manufactured to this day and is an excellent product. To the untrained eye, Super Six and Hardifence look quite similar. However, dealing with Super Six requires special precautions to be taken during its handling and for its disposal due to its asbestos content. Be careful not to dispose of any Super Six sheeting in general waste or skip bins not designed for asbestos disposal as you risk being charged a hefty asbestos disposal fee or even worse, a fine for illegal asbestos disposal. Is it asbestos Super Six or modern Hardifence? Tips to identify Super Six(asbestos) and Hardifence(non asbestos). Age of the house: A house built in the late 1. Super Six fencing installed. Although it’s possible second hand asbestos Super Six sheeting may have been reused the incidence of this is probably low. Likewise an older house is more likely to have asbestos Super Six asbestos fence, which may have been installed in the 1. Count the number of ridges: The latest version of Hardifence has 5 ridges which is a sure sign of being the asbestos free Hardifence rather than Super Six which has 7 ridges. However, to make matters confusing, early versions of Hardifence have the same profile (7 ridges) as Super Six. See picture above. These early versions of Hardifence were prone to breakage and often cracked off at the bottom. Also breakage near the diamond washer/nut & bolt fixing is also quite common. Hardies soon improved Hardifence with deeper corrugations and eliminated the washer, nut & bolt with the top metal capping becoming an integral part to keep the sheets from separating at the top. Markings: If possible, examine the edge of the sheet to see any indentifiable markings. Hardifence has “Hardifence” printed on there along with a date of manufacture. Early styles of Hardifence have “Manufactured without asbestos” and a manufacturing date mark. Capping: metal or asbestos cement. If the fence is fitted with fibre cement capping, then it’s a sure sign that the fence is asbestos. However, if the fence has metal capping then it’s most likely the fence is Hardifence and does not contain asbestos. The most recent version of Hardifence is always fitted with metal capping as this is an integral part which keeps the sheets from separating at the top. However, bear in mind that there are plenty of fences where no capping is fitted at all. Finger nail scratch test. Use your fingernail to scratch the surface of the sheet. If you can gouge a mark in it, then this is a good indicator of being Hardifence rather than Super Six. Generally Hardifence is slightly softer than Super Six. Using digital camera in macro mode: If you have a digital camera then use the macro mode setting to take a close up picture. Next, find a suitably broken corner or edge to photograph. You can then examine the type of material composition from the comfort of your computer monitor. Whilst asbestos fibres are microscopic, the asbestos fibre used in the manufacturing process of asbestos cement sheeting was in large clumps or bundles. These fibrous bundles can be seen sticking out near a breakage point or sometimes on a edge of the sheet when you examine the close up photo of your sample. From this you can determine whether or not the material is asbestos cement or not. By contrast, the cellulose fibres used in Hardifence tend to be bonded more uniformly and fibre lengths tend to be shorter and not as strong. As a result, broken edges of Hardifence almost resemble the appearance of torn cardboard with a soft fuzzy edging. In addition, broken edges of Hardifence may tend to have a layered appearance, probably due to the manufacturing process. Warning: Do not break any suspect asbestos cement sheeting when taking a close up photo as this will release deadly asbestos fibres which may be breathed in. Better to find an existing broken corner or edge to photograph. If there has been one redeeming factor about asbestos in Australia, it’s publicity generated by high profile court compensation claims during 8. I believe has resulted in a public awareness campaign that no State Government health department awareness program could ever hope to replicate. Not only has this created a huge general awareness of the dangers associated with asbestos for the general public, it has rocked corporate Australia with large compensation payouts and often with negative publicity for corporate social responsibility.

More about Eternit here: Eternit and the Great Asbestos Trial. Worldwide and just like in Australia, asbestos cement was a big part of the building industry, especially in the post war years where it was heavily promoted as a cheaper and faster alternative to traditional methods of building construction. In some parts of the world, asbestos is still a key component of fibre cement products, notably, India, Pakistan, Indonesia and China are still importing raw Chrysotile (white asbestos) for manufacture of asbestos cement products.

There is quite a coverage of asbestos cement sheeting on the roof and when the time comes for repairs or demolition, one wonders if the demolition crew will take the appropriate safety precautions for asbestos disposal to prevent the workers and neighbours being exposed to asbestos fibres. Secondly, the demolition crew should be aware of the risk of . Also inside the house there could be more asbestos, such flat sheeting on the ceiling or walls and dangerous friable asbestos lagging over hot water pipes. Broken asbestos sheeting left in vacant lot. Mostar, Bosnia & Herzegovina. Photo by Jason Kovacevic. Indiscriminate or illegal dumping looks to be a problem in Bosnia & Herzegovina also. Breaking up sheets like this can release dangerous asbestos fibres into the surroundings which can be inhaled. Asbestos roof of a restaurant in the small town of Celebici. Photo by Jason Kovacevic.
