Frequently Asked Questions
At Shed Centre® we pride ourselves on offering our clients a hassle free way to navigate your entire project – from plans to permits, design to delivery.
When looking to buy or build a cold-rolled steel shed or garage in Australia, navigating local building regulations, weather conditions, and supplier options can feel a bit overwhelming.
Shed Centre® can assist in the design consultation for projects throughout Australia. However, as a local Victorian based manufacturer, we have a dedicated and experienced team who know how to navigate state-specific guidelines.
Here are some of the most frequently asked questions specific to buying and structuring a steel shed in Victoria:
Do I need a council building permit for a shed in Victoria?
Yes, in almost all cases. Under Victorian building regulations, you generally need a building permit for any steel garage or shed unless it is a small garden shed (under 10m2 in floor area, under 2.4 meters high, and not attached to another structure). For typical cold-rolled garages or farm sheds, you will need to submit engineered plans to a local council or private building surveyor.
Shed Centre® offers “permit coordination” services for a flat fee of $1,395 where we handle the paperwork and submissions to your local council on your behalf.
We also have an affiliation with an experienced local Registered Building Surveyor (STA Building Consultants) to coordinate building permits, and an experienced local Town Planner and Property Consultant (Arcwell Drafting and Building Design) to coordinate planning permits.
How do Victoria's unique wind zones affect the structure of my shed?
Victoria has incredibly diverse weather geography—ranging from shielded residential suburbs in Melbourne to high-wind coastal strips along the Surf Coast or sub-alpine snow zones.
Shed Centre® utilises Site-Specific Engineering based on Australian Standards based on the exact GPS coordinates of the project location to ascertain the wind rating (e.g., N2, N3, or regional equivalents). If you are in a high-wind zone, the structural frame is engineered with thicker gauge steel or closer portal bay spacing.
What is the difference between "C-Section/Z-Purlin” frames and "RHS" frames?
When looking at Victorian suppliers, you will notice two distinct framing styles:
- Cold-Rolled C-Sections/Z-Purlins: Light-gauge sheets of steel rolled at room temperature into “C” shapes. They are incredibly cost-effective, lightweight to transport, and connect using bolted brackets.
- RHS (Rectangular Hollow Section): Thicker, traditional welded box steel frames.
While C-sections dominate the modern kit-shed market for their value and ease of assembly, some local manufacturers still specialize in heavy-duty RHS frames for buyers looking for maximum structural rigidity or specific industrial uses.
Shed Centre® utilises Engineering based on Cold-Rolled C-Sections/Z-Purlins for the majority of its designs.
Is the steel used by Shedcentre genuinely Australian made?
This is a critical structural question because cheap imported steel often lacks the tensile strength required by local codes.
Shed Centre® proudly supports 100% Australian BlueScope Steel, featuring genuine COLORBOND® or ZINCALUME® cladding, and GALVASPAN® for the structural cold-rolled portal frames.
This steel comes with warranties up to 20 years and is specifically formulated to withstand 6.
Can I build a cold-rolled shed kit myself, or do I need a registered builder?
In Victoria, this comes down to the cost of the project and your legal status:
- As a DIYer (Owner-Builder): If the value of the domestic building work exceeds $16,000, you must obtain an Owner-Builder Certificate of Consent from the Victorian Building Authority (VBA) before you can pull a permit and build the kit yourself.
- Hiring an Installer: If you choose not to do it yourself, the person installing your shed must be a VBA-registered building practitioner if the work is over $10,000. Many suppliers sell the shed as a “supply-only” kit but can recommend a network of local, trusted, and licensed erectors to lay the concrete slab and stand the steel frame.
When planning, purchasing, or engineering a cold-rolled steel garage (often structured around lightweight, high-tensile C-sections and Z-purlins), buyers and builders consistently flag a specific set of structural and logistical questions.
What is the maximum size and span possible with a cold-rolled steel frame?
Because cold-rolled steel is made from lighter-gauge sheets shaped at room temperature, it is incredibly strong but has structural limits compared to heavy, hot-rolled structural steel beams.
Generally, Shed Centre® will design a clear span (the width of the garage without internal support columns) up to around 20 metres.
Eave heights typically max out around 6 metres.
While the length of the garage is theoretically infinite (you just keep adding portal bays), exceeding these width and height limits usually requires a pivot to traditional heavy structural steel.
How does the foundation requirement differ from traditional builds?
Cold-rolled garages utilise a “portal frame” methodology where lightweight posts bear the structural load. Because the overall framework is much lighter than timber or hot-rolled steel, the foundation requirements are often less massive, saving on initial concrete costs.
However, cold-rolled structures require highly precise footings.
Upright posts are usually bolted directly into concrete pads or a slab utilising heavy-duty brackets.
Engineering schematics for the slab must be calculated concurrently with the garage design to ensure the concrete can handle the specific localised wind-uplift forces.
A Shed Centre® structural design consultant will be able to provide you with the foundation design to ensure the total project is structurally complete.
What are the lead times and shipping logistics for a supplied kit?
Shed Centre® partners with local leading manufacturers and suppliers. Because cold-rolled components are manufactured from coils of flat steel wound through a roll-former, production is incredibly fast.
Lead times from finalising engineering drawings to scheduling the delivery to site of the structural steel, cladding and supporting components (roller doors, personal access doors, gutters, downpipes, windows and insulation) usually ranges from 3 to 6 weeks.
Logistically, cold-rolled profiles (C and Z sections) are designed to nest tightly into one another. This dense stackability means an entire double or triple garage kit can often fit onto a single delivery crane operated flatbed. Delivery is made to the most accessible property location and most often will be delivered to the kerbside (nature-strip) in front of the site..
