Shed – eye for detail.

Sheds come in different types

The majority of sheds sold today in Australia are of the portal frame design and the components are what is called cold rollformed. But there are two other important types of shed construction that is becoming more popular, the structural steel frame and the stud frame sheds. This is a quick rundown on the three different types:

 

1. Cold rollformed portal frame shed.

This is the most common type of shed and is normally supplied pre-engineered and in a kit form. The main structure (called the portal frame) consists of rolled purlins, girts, batton, top hat and brackets. The cladding and flashings are common to all types.

As you can see the basic prinicple is that all the purlins (both rafters and colums) consist of cold rolled C section joined by fabricated brackets that bolt each assembly together. The roof and wall members are added once all the portal frames have been stood. This is a very efficient system that can be transported easily and assembled on site with minimal tools. 

 

2. Structural fabricated steel shed.

 Nearly the same engineering prinicple as number 1 – except all the colums and rafters are from hot rolled section such as H section, I beam, or C channels with welded cleats and joiners on all ends. All other components are normally the same. The advantage of this type of design is for larger spans especially used in large warehouse constructions and normally over 18 meter width.

The structural steel is heavy to transport but does allow faster erection and extremely high strength joining system. All the other components are very similar.

 

3. Steel stud framed sheds.

 Now this is completely different to the above two. It is identical to the steel stud framing used in housing and results in a very strong overall construction. The walls and trusses are all prefabicated in sections and simply stood on site and then clad. The advantage of this system is the ease of which you finish the sheeting internally and is the reason it is gaining popularity.

As you can see there are no colums protruding into the interior and all window and door penetrations are done at fabrication stage. While slightly more to transport – the erection time is greatly reduced and the finish (interior) allows much cheaper cladding solutions. It can be treated in the same way as a normal house frame.

    Great article Shedeye.

    [URL=”http://blog.shedeye.com.au/2012/10/shed-eye-for-detail/”]Shed eye for Detail[/URL] is a very good description of the different types of shed available.

    My personnel preference is the steel stud frame design because of the extra gain of internal area. For example in a 10 x 6 – you can save up to over 3 square meters if the columns are 250mm C purlins.
