Choose open steel shelving for bulk items you grab often, and a lockable metal cabinet for anything valuable, hazardous or messy-looking — most organised Australian garages end up with both, roughly two bays of shelving for every one cabinet.
The two formats solve different problems, and buying the wrong one first is the most common garage storage mistake we see. This guide compares them on cost, capacity, security and dust, then gives a simple zoning method.
Key takeaways
- Open shelving is the cheaper way to store volume; cabinets buy security and a clean look, not capacity.
- A lockable double-door steel cabinet starts around $175 AUD and a full-height 1.85m unit around $285 AUD at Steel Power Shelving, while garage shelving bays start under $200 — so a starter setup with both formats is achievable for roughly $500.
- Anything a visitor should not see, touch or borrow belongs in the cabinet: chemicals, chargers, hand power tools, paperwork.
- Dust and light matter: cabinets keep camping gear and fabric items clean through a Queensland summer; open shelves do not.
What each format does best
| Criterion | Open steel shelving | Lockable metal cabinet |
|---|---|---|
| Cost per stored item | Lower — nothing spent on doors or locks | Higher — you pay for enclosure |
| Access speed | Instant, both hands free | Two steps: unlock, open |
| Security | None | Lockable doors or drawers |
| Dust and sun protection | No | Yes |
| Visual tidiness | Everything on show | Everything hidden |
| Weight of stored goods | Suited to heavy bulk storage — see our load rating guide | Suited to tools, files and household goods |
Which items go where?
Put on open shelving
- Storage tubs and seasonal boxes (label the short side facing out)
- Bulky hardware, paint-free renovation leftovers, timber offcuts
- Car care and camping bulk that is neither valuable nor weather-sensitive
Put in a metal cabinet
- Garden chemicals and pool chemicals, out of children's reach and locked
- Power tools, batteries and chargers — the most commonly stolen garage items
- Documents, manuals and anything paper: a steel file cabinet keeps them flat and dust-free
- Fabric goods: sports bags, tents, seat covers
How to plan a mixed setup: 4 steps
Step 1: Count your "lockable" items first
Walk the garage and list what genuinely needs locking or hiding. Most households fill one cabinet; a serious tool collection fills two.
Step 2: Size the cabinet to the wall gap
Full-height 1.85m x 0.9m cabinets maximise storage per square metre of floor; compact 2-drawer units suit under-bench gaps. Both formats are compared in our metal storage cabinet guide.
Step 3: Give everything else to shelving bays
Measure the remaining wall run and divide by bay width. Keep one empty shelf per bay — garages accumulate.
Step 4: Zone by frequency
Weekly items at waist-to-shoulder height on open shelves; monthly items higher; locked items in the cabinet regardless of frequency.
What does each option cost in Australia?
At Steel Power Shelving (Brisbane): a compact 2-drawer lockable cabinet is $145, a lockable double-door cabinet with adjustable shelf $175, full-height 1.85m cabinets $285, and a tool cabinet with integrated pegboard $399. Steel shelving bays are priced per bay by width and load rating — the heavy duty shelving guide covers current options. Prices correct at publication.
How Steel Power Shelving approaches it
Steel Power Shelving supplies both formats from the same Brisbane (Willawong) warehouse, in matching powder-coated steel, so a mixed wall looks like one system rather than a patchwork. Same-day pickup is available on in-stock items, and both ranges can be inspected in person during opening hours (Mon–Fri 9–5, Sat 9–4, Sun 10–4).
Frequently asked questions
Is a cabinet or shelving better for a small single garage?
Start with one full-height cabinet in the corner for everything lockable, then add shelving along the remaining wall. In tight spaces the cabinet earns its footprint by going full-height.
Can open shelving and cabinets sit side by side?
Yes, and it usually looks intentional if heights align — a 1.85m cabinet sits flush beside standard garage shelving bays.
What should never go on open garage shelves?
Chemicals within children's reach, lithium batteries in direct sun, documents, and anything you would mind a tradesperson or neighbour seeing or borrowing.
Do metal cabinets rust in coastal Queensland garages?
Powder-coated steel resists surface corrosion in normal garage conditions. Wipe down salt-air film occasionally and avoid trapping wet items inside.
Which holds more weight — a cabinet shelf or a shelving bay?
Open steel shelving is the format built for heavy loads; treat cabinets as organisers rather than heavy-load storage, and check the product page rating for anything heavy.
Are flat-pack cabinets from big-box stores comparable?
Flat-pack MDF and thin-steel units cost less upfront but handle garage humidity and knocks poorly. Our metal vs flat-pack comparison covers the differences in detail.
Can I lock up only part of my storage without buying a cabinet?
Lockable job-site boxes work for a handful of tools, but per litre of storage a cabinet is usually the cheaper and tidier answer once you pass two or three toolboxes.
What is the fastest way to get set up in Brisbane?
Order online, confirm stock, and collect the same day from Willawong — the same-day pickup guide explains how it works.
