How to Combine Steel Shelving and Lockable Cabinets in One Garage

By Steel Power Shelving Team | Published: 20 September 2026

Run open boltless steel shelving for everything bulky and used often, add one or two lockable metal cabinets for chemicals, power tools and valuables, then set them side by side along a single wall with matching heights — 1.85m cabinets beside 1.8m or 2.0m shelving — so the run works as one system instead of two separate purchases.

Most garage storage advice asks you to pick a side: open shelving or closed cabinets. In practice, almost nobody who fits out a whole garage ends up with only one. Shelving is the cheapest way to hold volume and the fastest way to find something; a cabinet is the only way to lock a door on what shouldn't be reachable. This guide is about running both — choosing the shelving for bulk and visibility, then adding cabinet space for what has to be locked, hidden or kept clean, and lining the two up so the finished wall looks deliberate. If you are still weighing the two against each other, our comparison of a metal cabinet versus open shelving in an Australian garage covers that decision first.

Key takeaways

• Open shelving earns its place on visibility and bulk: anything you reach for weekly, and anything too large to fit through a cabinet door, belongs on show.
• Cabinet doors earn their place on control: chemicals, fuels, power tools, valuables and anything you want out of sight or away from children.
• Match heights so the run reads as one piece — the 1.85m H x 0.9m W x 0.4m D cabinets at $285 finish within 50mm of 1.8m shelving, while 2.0m shelving leaves about 150mm of shelf line running above the cabinet.
• Load is rated per shelf, not per unit: 200kg per shelf on the 0.5m deep line, 300kg per shelf on the 0.6m deep line. Our cabinets publish no kg capacity at all, so never plan one as load-bearing storage.
• Leave a working gap at bench height rather than filling the wall — the 0.89m H x 0.915m W x 0.6m D lockable cabinet with shelf at $175 is bench height on its own.

The decision rule: on show or behind doors

Work through the garage item by item and ask two questions. Do I need to see it to find it? Do I need to stop someone else getting to it? The first question sends things to open shelving, the second sends them to a cabinet.

Open shelving suits:

• Bulky, awkward items — camping gear, eskies, tubs of sports equipment, paint tins, tyres and wheels.
• Anything used weekly, where opening a door and moving something else is a daily annoyance.
• Heavy items you want to slide straight on and off at waist height, on a shelf rated 200kg or 300kg per shelf depending on the depth you chose.
• Labelled tubs and clear crates, where the whole point is reading the label from two metres away.

A cabinet with a lock suits:

• Chemicals and fuels — pool chlorine, weed killer, two-stroke, solvents, spray cans.
• Power tools and battery kits, which are both the most stealable and the most dangerous things in most garages.
• Sharp hand tools, blades and fixings you don't want a curious child reaching.
• Anything that must stay clean and dust-free: documents, spare linen, soft goods, seasonal clothing.
• Anything you simply don't want on display when the roller door is up.

The honest limit is this: a cabinet is an enclosure, not a shelf. Our cabinets don't publish a kilogram rating, so the per-shelf numbers you see on our shelving — 200kg per shelf or 300kg per shelf — do not transfer to them. Keep the dense, heavy load on the shelving and use the cabinet for what needs a door. If the difference between per-shelf and headline total figures is new to you, read why we quote load per shelf rather than per unit.

Lay the two out along one wall

Measure the wall before you buy anything, and measure it at the height the units will actually occupy — not at floor level, where the skirting, the power point and the garden tap all live. Then plan the run left to right in three zones.

• The bulk end. Put the longest shelving bay at the end of the wall you walk past least. This is where seasonal and rarely touched stock goes, top and bottom shelves included.
• The working zone. In the middle, keep the shelf you use most at bench height and leave the space in front of it clear. A bench-height cabinet such as the 0.89m unit gives you a working top and a locked space underneath in the same footprint.
• The secure end. Finish with the full-height cabinet, ideally near the internal door rather than the roller door, so the locked items are the furthest thing from the street.

Keep both the shelving and the cabinet on the same wall line rather than putting the cabinet on a return wall. One continuous run is easier to load, easier to sweep under and looks like a fit-out instead of a collection of units. Our workshop fit-out layout guide works through the same zoning for a bench-based workshop.

Match the heights so it looks built-in

The detail that decides whether the wall looks planned is the top line. Our cabinet heights and shelving heights are close enough to pair cleanly if you choose on purpose.

Depth is the other half of the match. The 0.5m deep shelving line sits close to the 0.5m deep tool cabinet and mirrored wardrobes, while the 0.6m deep shelving line stands about 200mm prouder than the 0.4m deep full-height cabinets — which is often what you want, because it gives the cabinet doors room to swing.

Three pairings from the in-stock range

These are real combinations from stock as scanned on 20 September 2026. Prices are as listed on the site in AUD and subject to change, and each unit is priced on its own — there is no package price.

If your wall is longer, the usual move is a second shelving bay rather than a second cabinet: most garages need one locked door and a lot of shelf. For a locked door under $200 on its own, the 0.89m cabinet with shelf at $175 and the 3-drawer mobile pedestal at $160 are the two to look at, and we compare the small options in our guide to small lockable metal cabinets under $200.

Fix both to the wall before you load a thing

A combination run has two anti-tip jobs, not one. Tall boltless shelving needs bracing or anchoring so it can't walk forward as you pull weight off the top shelf, and a full-height cabinet on four feet is even easier to tip once the top shelf inside is loaded and both doors are open. Anchor each unit to the wall on its own fixings — don't rely on the neighbouring unit to hold it.

• Set the run against a solid wall and level every unit on the slab before it carries anything; a garage floor almost always falls towards the door.
• Load bottom-heavy: the heaviest items go on the lowest shelves and in the bottom of the cabinet.
• Keep chemicals off the top shelf entirely, whether it's open shelving or inside a cabinet — you don't want to reach blind above head height for a container of liquid.
• Keep a spare cabinet key somewhere other than the garage.

Our step-by-step guides cover each fixing job: anchoring steel shelving to a concrete floor or wall and securing a metal storage cabinet.

Every shelving unit and cabinet named here was in stock at both warehouses when we checked on 20 September 2026 — Willawong in Brisbane, where same-day in-store pickup is available, and Wetherill Park in Sydney — with Australia-wide delivery from either. Our store average is 4.8 stars. If you want a second opinion on a pairing before you buy, ring Brisbane on 07 3879 0357 or Sydney on 02 9823 9703 with your wall measurement and what you need to lock away.

Do I need cabinets at all if I already have open shelving?

Only if something in the garage needs a locked door or a dust-free space. Shelving handles volume and visibility perfectly well on its own, but it cannot keep pool chemicals away from a toddler or a cordless kit out of sight. Most people add a single full-height cabinet to an existing shelving wall rather than replacing any shelving.

What must go behind locked doors rather than on open shelving?

Chemicals and fuels, power tools and battery kits, sharp hand tools and blades, and anything valuable or personal. The test is whether you would be comfortable with a child or a stranger reaching it while the roller door is up. Everything else — tubs, camping gear, tyres, paint tins — is better on open shelving where you can see it.

How much wall length does a shelving and cabinet run take?

Add the shelving length to the cabinet width. A 2.0m long shelving bay next to a 0.9m wide full-height cabinet needs about 2.9m; the same bay beside the 1.0m long tool cabinet with pegboard needs about 3.0m. A smaller starter pairing — a 1.2m bay plus the 0.915m wide bench-height cabinet — fits in just over 2.1m.

How much weight can a metal storage cabinet hold?

We don't publish a kilogram capacity for our cabinets, so we won't quote one. Per-shelf load ratings apply to our shelving only: 200kg per shelf on the 0.5m deep line and 300kg per shelf on the 0.6m deep line, evenly distributed. Plan the cabinet for enclosure and security, and put the dense, heavy load on the shelving.

Will a 1.85m cabinet look wrong beside 2.0m shelving?

No, as long as you choose it deliberately. At 1.85m against 2.0m shelving, the cabinet sits about 150mm below the shelf line, which reads as a deliberate step rather than a mismatch. If you want a flush top line instead, pair the 1.85m cabinets with 1.8m shelving, or the 1.80m tool cabinet with 1.8m shelving.

Can I buy the shelving and the cabinet together as a package?

Each unit is sold and priced individually as listed on its product page, in AUD and subject to change, so build the combination you actually need rather than taking a fixed set. If you are putting an order together for pickup or delivery, call the warehouse and we will confirm current stock on every item in the run before you commit.
