Different types of gutters for your shed

The rules and recommendations for steel structures

When you’re considering building a new shed, you will need to make sure your design is compliant with the National Construction Code (previously known as the Building Code of Australia).

The Code is in place to make sure any commercial, residential or industrial structures are built safely and will last for many years to come. It covers hundreds of different aspects of building, including how guttering should be selected and installed.

Regulations for gutters on your shed

The National Construction Code has specific requirements for the disposal of surface water that is collected by your shed roof. The simplest way to ensure your shed complies with the Code is by using the right roof drainage – or guttering – that meets Australian Standards, and is compliant with any special regulations in your State.

As a quick overview, there are a series of different rules and recommendations that apply to shed guttering, including the National Construction Code and the Australian Standard that is commonly referred to in the industry as the Plumbing Code.

Regulations that apply to shed guttering

  • National Plumbing and Drainage Code AS/NZS 3500.3
    This provides calculations that allow building designers to work out the surface catchment area of the roof, consider the potential rainfall it will have to handle, and in turn recommend an appropriately sized gutter. It takes into account slope, gradients and the shape of the roof, as well as the typical annual rainfall for your area.


  • NCC Volume One, Performance Requirements FP1.2 and FP 1.3
    In simple terms, this section of the Code refers to commercial sheds. It covers aspects like preventing rainwater from entering a building by waterproofing it to withstand a 100-year flood, directing surface water from storms to a channel or downpipe, and preventing water from damaging the building.


  • NCC Volume Two, Part 3.5.2, Performance Requirement P2.2.1 and Clauses to
    This section of the Code is mainly for residential buildings (which some smaller sheds can be classified as). It provides similar guidance to the above, namely that your shed needs to withstand serious rainfall events.

How to navigate these requirements

Interpreting the Code can be complex and confusing, which is why we’re here to help. Our team are experienced in creating commercial and rural shed designs that are compliant with the above Codes and your local legislation, so we can provide guidance and recommendations on the best gutter for your shed.

Recommended gutters for sheds

We use Stramit gutters in a few different styles, which fit various types of sheds. Fascia and half-round guttering systems are available in a wide range of COLORBOND® colours to perfectly complement your shed design.

Fascia gutter
Made of high tensile steel, fascia gutters provide continuous support and suit a range of design styles from traditional to contemporary sheds. Coated with a Zinc, Aluminium and Magnesium alloy and finished in COLORBOND® steel, fascia gutters are extremely durable.

Half-round gutters
With a rounded profile, the half-round gutters have a high water carrying capacity and a curved profile that promotes self-cleaning. Like fascia gutters, they are coated for corrosion resistance and available in COLORBOND® colours.

Custom box gutter
Simple box gutters are tough and hard-wearing, with neat clean lines that complement all types of shed designs. Customising box gutters for your individual project is a cost-effective solution that means we can get the perfect length and profile for your shed. Plus, because they are custom sized, this minimises the number of downpipes required. Custom gutters are tailored to your particular shed size, location and rainfall intensity.

Not sure which gutter is right for your shed?

The team at Steelcorp is here to help you find the best guttering that will provide reliable, long-term rainwater management.

Our experienced designers ensure that gutters are appropriately sized for your shed roof, resulting in minimal risk of overflow and no water leakage behind the fascia and into the interior of the structure.
