Checklist to Make Sure Your Shed or Mezzanine Floor Complies

  • Roof and Wall Sheets should be G550 Steel. Avoid material with less strength.
  • The frame (columns, rafters, purlins and girts) should be G450 or higher. The grade and manufacturer of the steel should be included.
  • Maximum deflections (amount of 'sag' in the steel) should be mentioned and shown to pass current Australian standards.
  • The amount of lateral bracing required should be shown and proven to pass Australian standards.
  • The weight of the shed or floor materials should be included and be fully auditable (the industry is prone to exaggeration)
  • You should be able to see an example of their structural documentation, so you know what you are getting.

Are you looking for quality shed, garage or mezzanine floor kit?

Our aim is to supply the best shed, garage or mezzanine floor for your situation. At Excalibur Steel Buildings, you can choose from a large range of genuine colorbond sheds and garages to suit many purposes. Discover many different sizes and heights, that you can order to suit your own personal needs. Additions such as roller doors, PA (personal access) doors, windows and insulation are also available. Mezzanine floors come in a strong galvanised frame.

We Encourage You To Do Your Homework Before Buying. 

You will probably notice wide varying prices when searching for your shed, garage or mezzanine floor. We don't expect you to know all the details, but you should be able to make the best decision by talking with a few people and getting the right information. Two of the main differences in sheds etc. is due to where the steel is coming from, and how strong the shed is designed.

  • Australian steel will cost you more initially, but save you thousands in the end. It's simply made to last, and look better for much longer. There is only one range of genuine Colorbond. All the colours are trademarked as well. 
  • How the shed is designed is also a consideration. It needs to pass the building code and Australian standards (because Australian steel is made here, it passes the standards). It should be strong, typically from high tensile steel feed (as opposed to soft feed, which you can find). You will find variations in how the same size building, from different suppliers, have been engineered. Ask for the size and thickness of the steel components and how much is used. Look for the strength rating of steel quoted as well the weight of steel in the shed - this will tell you if it's lightweight or not as strong. 

Engineered Shed Designs for Both Non-Cyclonic and Cyclonic Wind Conditions

One of the main things to get right when ordering shed kits is to make sure that your shed has been designed for your local conditions and that it includes the proper engineering paperwork. There is a big difference between non-cyclonic and cyclonic wind areas and you need to know that your shed kit can handle it. Excalibur Steel Buildings can provide with the engineering documentation for your shed, including your site address details. This then gives you site specific engineering, showing your shed design matches with your location correctly.
