What to Look for When Buying a Mezzanine Floor in Sydney.

September 18, 2025

You’re thinking about buying a mezzanine floor in Sydney. Good call. Mezzanines can unlock valuable extra space without costly extensions. But the market’s full of options—and not all of them are worth your time or money.

Here’s the no-nonsense guide to what matters when choosing a mezzanine floor. We’ll cut through

really need to consider avoiding buying a lemon or ending up with a structure that’s unsafe, non-compliant, or just plain useless.

1. Purpose and Mezzanine Load Capacity: Define What You’re Building For

First off, be clear on what the floor will do.

Function:
Will it be for storage? Office space? Light foot traffic? Heavy machinery?
Each use demands different load bearing capacity and design.
Load Rating:
Don’t guess here. Mezzanine floors are rated by how much weight they can hold, measured in kilopascals (kPa). Too weak? You risk structural failure. Too strong? You’re overpaying for unnecessary specs. Get it right up front. The staff at Car Covers and Shelter can help you choose what load capacity you require. For most mezzanine floor uses 3kpa, that’s 300kg per square metre is sufficient.
Clearance Height:
How much room do you have beneath the mezzanine? Make sure you leave enough vertical clearance so that this new floor doesn’t cramp your existing space or operations. Remember, a mezzanine is supported by beams. A decent quality mezzanine will have at least 150mm beams so this is 150mm below the floor that will reduce the clearance from the chosen floor height.

Bottom line: If you don’t clearly define purpose and load requirements, you’ll regret it later.

2. Mezzanine Floor Compliance and Safety Standards: No Shortcuts Here

Sydney isn’t a place to sidestep regulations. Mezzanine floors must tick all the right boxes according to Australian building codes.

Building Codes:
Your mezzanine must comply with the Building Code of Australia and relevant Australian Standards. Don’t assume your supplier knows—or cares—unless you check.
Australian Standards:

AS 1170: Covers loadings.
AS 1657: Covers permanent access systems (stairs, ladders, platforms)
AS 4100: Covers steel structures.

Stairs and Handrails:
Make sure stairs meet the rules for tread heights and riser dimensions. Guardrails (balustrades) must be at least one metre high with gaps small enough to stop accidents.

Your mezzanine floor from Car Covers and Shelter will be certified by Edge Consulting, the most respected and largest engineering group in Australia. Be careful of mezzanines certified by “in-house” engineers or one person ‘backyard’ engineers offering certification for a small price. Cutting corners on safety isn’t worth the risk or the fines down the line.

3. Structural Components and Material Quality: Look Under the Hood

Cheap materials and flimsy construction will fail you eventually—and that could be dangerous.

1. Support Beams:
These are the backbone and need to be solid steel, not lightweight or shoddy metal. Anything less and you’re gambling with stability. Steel beams should be used to support the floor. Top Hats are often used in cheaper mezzanines, but it is very unlikely they will conform to the Australian Standards.

2. Decking:
Options vary—wood, steel, composite panels—each with pros and cons dependent on load and use. Ignore marketing hype and focus on what suits your load and environment.

3. Column Spacing:
Too many columns make for clutter and lost floor space; too few can mean expensive custom engineering. Find a balance that makes your space flexible and efficient.

4. Mezzanine Design and Customisation: Fit It to Your Space, Not the Other Way Around

Don’t pick a generic mezzanine and expect it to magically suit your operations.

Layout:
Plan for efficiency and accessibility. Will the size and shape help your workflow, or just add a bulky nuisance? Every mezzanine supplied by Car Covers and Shelter is custom-designed to ensure you get exactly what you want.
Custom Features:
Stairs aren’t one-size-fits-all. Straight, spiral, or custom shapes all have pros and cons. The same goes for handrails and other safety features—your mezzanine should work with your specific site constraints, not fight them.

5. Choosing a Qualified Mezzanine Floor Provider: Your Best Insurance Policy

This is where a lot of buyers drop the ball. A cheap supplier might save you money upfront but cost you a fortune in headaches later.

Expertise and experience matters. Pick a provider like Car Covers and Shelter, with the backing and certification from Australia’s most respected Engineering Consultancy Group, experienced in designing and engineering, mezzanine floors in Sydney.
