Designed Withstand Australia’s Harshest Weather

When it comes to cyclonic steel buildings, strength and durability are non-negotiable. Sheds n Homes designs and supplies cyclone-rated sheds engineered to withstand Australia's most extreme weather conditions, from high winds to tropical storms. If you are building in Australia’s cyclonic zones, Wind Region Cyclone Region C or D, you can rest assured our structures are engineered and designed to meet or exceed The National Construction Code for cyclone-resistant construction. 

Why Choose a Sheds n Homes Cyclonic Shed?

✅ Engineered to Australian Standards – Our sheds comply with AS/NZS 1170.2 wind load standards, ensuring resistance to cyclone-force winds in cyclonic regions.

✅ BlueScope Steel & Colorbond® Cladding – Premium, high-tensile steel for maximum durability in extreme conditions—including wind and harsh Australian UV rays.

✅ Custom Designs with Site-Specific Engineering – Designed for your exact location to optimise performance against cyclonic forces.

✅ Bolted Portal Frame System – Secure and robust framing for enhanced structural integrity.

Understanding Cyclonic Shed Design

✔ Wind Region Classification

Australia’s cyclone-prone areas are categorised into Region C and Region D, where wind speeds can exceed 250 km/h. Our sheds are engineered to withstand the extreme conditions likely to be experienced at your location.

✔ Cyclonic Wind Pressure & High-Intensity Rainfall

Cyclonic wind pressure sequences and intense rainfall common in some Australian regions during summer months require vastly different building and roof designs compared to structures in low-wind and non-cyclonic areas.

The Sheds n Homes kit building design software factors in cyclonic wind regions and pressures to ensure compliance and durability.

✔ Key Features of Our Cyclonic Sheds

• Fully bolted shed frames using Z purlins and girts with cleats (not top hats).
• Purlins and girts with overlaps of 10% of the bay width (minimum requirement) PLUS an additional 100mm.
• Decreased spacings on purlins and girts to suit the design criteria of your site.
• Roof cladding, fasteners, and support members tested to Low-High-Low Testing (BCA 2009 standard cycle test method).
• Larger gutters with flashings to withstand increased wind speeds and heavy rainfall.

Your Cyclonic Building Checklist

When shopping around for Cyclone Shed Designs, make sure to compare quotes carefully. We recommend verifying the following:

Is it a shed safe accredited supplier?

✔️ Your building should be designed to correct criteria for your site:

• Terrain Category  
• Importance Level
• Shielding Factor
• Be cautious of suppliers who are not ShedSafe, and not providing site specific Wind Design.  
• Ask: are they ShedSafe Accredited?

✔️ Check the weight of the building – large price differences can indicate variations in steel mass.

✔️ Ensure both roof and wall sheeting are minimum 0.42 BMT (base metal thickness) and  insist on genuine BlueScope Steel  Colorbond or Zincalume

✔️ Roof screws should be supplied with cyclonic washers.

✔️ The building requires internal external pressure coefficients specific to the building design and site conditions, buying from Sheds n Homes, a ShedSafe Accredited Seller, ensures your shed is engineered to suit your site and conditions.

✔️ Roller doors should have an engineer-certified Windlock kit to prevent failure in storms.

✔️ Verify the fixing methods being used – Be wary of dyna bolts for structural columns, as they are not approved by the National Construction Code and Australian Standards.

✔️ Larger structures should include bridging in portal frames to prevent purlin roll.

✔️ Cyclonic sheds should feature a ridge cap designed to fit roof sheeting profiles (scribed) to prevent water ingress.
