Mezzanines - Mezzanine Floor Kit Delivered to Your Design

Professional Choice Sheds® are the go to solution for businesses looking to make the most of their industrial building, agricultural farm shed, barn or warehouse space. These mezzanine floors are made to the highest Australian Standards. You can have any storage class: – light, medium or heavy-duty, for the right storage solution for your business.


Not many mezzanine floors will have a vibration maximum of just 2mm. This requires enough steel of the right strength to match the Australian Standards. Check out a design and quote from Professional Choice against other suppliers and you will easily see the difference in the Professional Choice engineering quality.


Mezzanines can be custom designed in any shape or size you require.

Why Add a Mezzanine Floor? - Mezzanines

Mezzanine floors are structures constructed out of steel that create a second floor inside your existing space. This allows you to increase the available storage area in your warehouse, create a second floor for an office or double your business’ floor space without having to look for a new location.


The Professional Choice® mezzanine floor kit designs are free standing structures, engineered and fabricated in your local city to Australian standards. They are high quality steel structures that will last and can be used to provide your business with the added space it needs over the long term.


The fully comprehensive plans are the best available. Each joint has a Q-Reader video to assist in installation. They are a very cost-effective solution that make DIY installation easy.


Designed to your exact requirements, with a number of weight classes to choose from and the choice of DIY installation, A Professional Choice Sheds® Mezzanine gives you the most cost-effective solution for your storage needs.

Please Note for Mezzanine Floor Kit Quote Requests

The most important measurement we need is the dimensions inside of column to inside of column in your shed or warehouse. If you say, for example “It’s a 15×10 shed”, we’d assume you mean the concrete slab area – not the area you have to work with for assembling a mezzanine. Please be aware of any knee braces (on less expensive builds, these can be half way up a wall) or mullions – particularly at the gable end.

In other words, we need the exact measurements of the area you have to work in for your mezzanine – not the floor area.


Choices for your Custom Design Mezzanines

In Plane or Joist over bearer? – In Plane gives a better ‘clean’ finish for just a few dollars more.


Joist Centres – either 450 or 600 – 600 will be less expensive but will require the equivalent of Red Tongue particle board – 450 would require the equivalent of the cheaper yellow tongue so not much difference in finished price.

  • Footing Brackets – Cast in, Base plate or Brackets – we recommend base plates for most jobs.
  • Wide span or Deep span is available for easy vehicle entry underneath as well as our cheapest option.
  • Load rating – your choice of light, medium or heavy – 3kpa is our recommendation for most purposes but its easy to go less or up to 10kpa.
  • Hand rail and stairs – your choice – our high quality stairs can be easily substituted for cheaper options from your local Hardware store.
  • Structural wall support – easily done if you have a wall capable of taking the weight.

Australian Standards on Mezzanine floors

Deflection limits are extremely important and often ignored by many disreputable installers and manufacturers. Your floor should have a 2mm vibration maximum which would be virtually impossible to achieve using Tophat or low-gauge mild steel. We do not have an independent test for mezzanine floors as we do for Shed Health Test. The floor can experience an allowable ‘bend’ when loads are applied. Australia has Australian Standards for these, just like in shed building, but again these standards are often ignored. A professional, competent business like Professional Choice Sheds® will assist you in determining what your requirement demands are, then explain their proposal with their quote.

Again, if you have a metal shed or warehouse, it has barely the strength to carry its own weight. Do not allow the use of brackets against already over-stretched beams. This happens with a cheap mezzanine build. It’s OK to fix to existing structural walls. Your Australian high tensile steel mezzanine should be ‘stand alone” and this is what you get with Professional Choice Sheds®

The SMART Buyers Guide

  • Genuine Australian Colorbond Cladding – Carports & Awnings

    The Truth

    Colorbond is a trusted, proven, durable product.


    The Trick

    Deceptively market misleading colour names & gauges. Check for genuine Colorbond colours and only accept a minimum of 0.42BMT – that’s Base Metal Thickness.

  • Certified Australian G450-500 High Tensile Steel Columns & Rafters

    The Truth

    BlueScope Steel capacities and strength are proven and certified by Australian engineers.


    The Trick

    Deceptive companies claim to use ‘quality’ steel but deliver cheap imported inferior steel. What does this mean? – Our 6m x 6m carport is more 2 x heavier than most of our competition and the weight of 7m x 7m Professional Choice Steel Shed is 435kg heavier and stronger than its flimsy, foreign steel counterpart. Using less steel and weaker steel makes frames dangerous & illegal.

  • Certified Australian G450-550 High Tensile Steel Purlins & Girts

    The Truth

    BlueScope Steel’s certified quality, strength & durability.


    The Trick

    Some companies will use BlueScope Steel but cheat you by using smaller members and less of them. Stay clear of purlins or girts with a gauge less than 1.0 mm. Cladding needs support and a frame needs substance or it will pull apart in a severe storm.

  • Comprehensive & User Friendly Instructions

    The Truth

    Product quality is obvious in its documentation. Every connection should be clear and have its own video showing you exactly what to do so you will have no mistakes and no wasted time.


    The Trick

    Distract buyers with glossy brochures, fancy ads and celebrities. Dig deeper to see what you are actually buying so compare Installation Manuals. Product quality is not skin deep and don’t be left scratching your head over a pile of parts.

  • Certified by Independent Reputable Structural Engineers

    The Truth

    Certified as 100% Australian Standards compliant.


    The Trick

    Be wary of ‘in house’ engineers or ‘back yard’ certifiers and look for a reputable, independent firms. CHECK ALL YOU ARE GIVEN on the independent website www.shedhealthtest.com.au

  • Shed Health Test

    If you already have a quote for your new steel building, we strongly recommend that you check the engineering here at this independent site shedhealthtest.com.au. 


    Unless its Professional Choice®, you will almost certainly find that your choice is not up to Australian standards
