Farm Sheds or Barn Professional Choice

Farm Sheds, Barns  Garages Workshops and Industrial Buildings

Please do NOT compare these sheds to the large shed suppliers in Australia. These sheds are built to genuine Australian Standards. This means there will be very little movement even in the strongest winds and they will never be damaged by winds.

The mass/weight will show that they are 40% heavier than any comparable size shed. They must be to meet accurate Australian Standards calculations and they MUST be High Tensile Steel, not weaker, cheaper imported mild steel.

The Professional Choice differences - Farm Sheds or Barn Professional Choice

Slab Size: A shed built to 6000 x 9000 fits on a 6x9 slab size. The steel frame and cladding extend past and over the slab for waterproofing.

Roller Doors. – The doors are defined by the size by the actual clearance of the opening with the roller door completely open and its drum at its maximum diameter.  With nearly all others shed manufacturers you will ‘loose’ around 300mm clearance with a door drum under-hang.

The parts Schedule. - An intelligent Bill of Materials designed to be read alongside the engineering Designs, so that you or the installers have the parts as you need them.  You will see that the designs set a new benchmark in the industry.  All designs satisfy both the Australian Standards and the Manufacturer's Specifications.

Your shed connection detail secures the purlin to the rafter using a high tensile M12 bolt, two 38 x 38 x 3 mm square washers and 6 Tek screws for lapped members.  

The structural integrity of this connection is obvious.

Farm Sheds or Barn Professional Choice

Strong enough to be lined (lining not included in price) and can be engineered, at little or no extra cost, to have the strength to retrofit solar panels on the roof. Most sheds and garages available in Australia aren't structurally sound enough to support any additional weight.  

“Solar Ready” allows for an addition dead load of 20 kg/m2 on top of the structure allowing the necessary strength to install solar panels. 

Farm Sheds or Barn Professional Choice

Everything is customisable to the millimeter.  You can use Zincalume or all Colorbond colours, add translucent or transparent roof sheets, PA Doors, Windows, Whirlybirds, Insulation, etc.

It’s an installer's dream.  Instantly accessible, clear, comprehensive instructions.

 Investing in a carport or shed you should know you're getting a quality steel building.

Professional Choice Can be up to 40% heavier than similar structures in Australia

Professional Choice design and use of steel is as efficient as it can possibly be and yet these structures are heavier than all on the market – Why?

Specifications for Lysaght Trimdek - Car Covers and Shelter Professional Choice Sheds and Garages

Most sheds or garages have TRIMDEC or CUSTOM ORB sheeting attaching (or Chinese import equivalent) to 75mm or less BMT (Base Metal Thickness) and yet the manufacturer specification is a minimum of 1mm BMT. Unless the framing is very close (400mm-450mm which is unlikely on most structurers), they do not meet manufacturer specification and are therefore do not meet NCC compliance – no matter what the engineering certification says.

High Tensile Australian Steel

There is a big difference in the quality high tensile steel made in Australia and the much cheaper mild steel imported from China, India or Korea used by most shed manufacturers in Australia.

Mild Steel not strong enough (unless you use heaps of it!)

el does not have the strength and is lighter than quality Australian steel*. These are just some points as to why Professional Choice is your guarantee that your new installation will meet all manufacturing and Australian standards.

State-of-the-art Engineering Plans

The unique design and engineering software used, ensures we're able to customise your carport or shed to the millimetre. There is absolutely no waste. They contain more steel than almost all competitors because a shed must be up to Australian Standards. Site-specific engineering to ensure they will withstand your specific conditions. Knowing that they will not be rejected by any possible insurance claim gives you peace-of-mind !

*(Chinese steel is Q235 or 235 MPa.  It is cheaper because it is weaker.  There is no heat treatment in the manufacturing process.  It does not have the strength of Australian G250 'mild' steel, let alone BlueScope’s high tensile G450-550 products.

The Australian high tensile 'G' rating refers to the steel's strength.  G550 is 550 MPa and applies to members up to and equal to 1.0 mm.  Members with a 1.2 mm gauge are G500 and have a yield of 500 MPa.  Gauges of 1.5+ are G450 or 450 MPa.)

The Professional Choice differences – Carports and sheds

For years, most Aussie shed businesses have been on a race to the bottom trying to offer cheaper and cheaper sheds and carports. This has been done at the expense of quality and strength.

Certifiers 'hiding' behind complex calculations

Certifiers have been able to ‘hide’ behind their complex calculations. Now, it’s easy for anyone to check for Australian Standards with the Shed Health Test – no more hiding! Make sure you buy the best – or at the very least, a shed that is Australian Standards compliant.

If you already have a quote for your new steel building, we strongly recommend that you check the engineering here at this independent site Unless its Professional Choice, you will almost certainly find that your choice is not up to Australian standards.

Professional Choice Can be up to 40% heavier than similar structures in Australia –

Professional Choice design and use of steel is as efficient as it can possibly be and yet these structures are heavier than all on the market – Why?

Quite simply, according to BlueScope Steel, you should NOT attach any Colorbond product to anything less than 1mm thick steel – Virtually no Australian manufacturer is compliant to this. Purlins spacing is ‘stretched’ to save on steel or lower thickness imported ‘Colorbond” imported “look-a- like” is used.


Accredited & National Construction Code (NCC) Compliant – Is your shed or carport really NCC compliant?
It’s probably ‘Australian made” or maybe just “Australian assembled” but NOT with Australian steel!
It may be sold with an Australian certification but very few are compliant with the Australian Standards. You can depend on Professional Choice
