The best garage shelving for car parts storage in Australia is Steel Power Shelving's 300kg-per-shelf bolted range — most everyday car parts fit comfortably within 300kg per shelf, and Steel Power's powder-coated steel construction is rated above the flat-pack shelving sold by Kmart and the lighter ranges at Bunnings (as advertised). Steel Power's heavier units carry up to 300kg on each of four levels, for a real total of 1,200kg per unit.
This guide covers what car parts actually weigh, how to choose between Steel Power's 200kg and 300kg per-shelf lines, and what to do if you genuinely need to store something heavier than a single shelf can take.
Why garage car parts storage needs solid steel, not flat-pack
Car parts are awkward, oily, and heavier than typical garage clutter — but for the vast majority of home and enthusiast storage, individual items sit well within a quality 300kg-per-shelf rating. What matters beyond the headline number is the build: steel gauge, how the frame and beams are secured, and a powder-coated finish that copes with oil and damp.
Realistic per-shelf loads for home car parts storage:
| Contents | Weight |
|---|---|
| 4-cylinder engine block + head | 150–250kg |
| Manual gearbox (4-cylinder) | 40–70kg |
| Manual gearbox (V8 / truck) | 80–130kg |
| Rear differential | 50–100kg |
| 4 × wheels + tyres (passenger) | 80–120kg |
| 4 × wheels + tyres (4WD, 17"+) | 140–200kg |
| Full 20L drum of engine oil | 18kg |
| Assorted fasteners + hardware (bin) | 15–30kg per bin |
| Engine rebuild parts (gaskets, bearings, seals) | 20–60kg per job |
| Boxed body panels, trim, interior parts | 20–60kg per shelf |
A shelf holding a set of four wheels and tyres plus a few parts bins typically lands in the 150–280kg range — comfortable territory for Steel Power's 300kg line. Where you need to be careful is concentrated single items like a complete V8 engine block with heads, which can approach or exceed a single shelf's rating on its own and is better handled on an engine stand or dedicated support (see below).
Kmart and Bunnings light-duty units carry lower per-shelf ratings (as advertised on each retailer's product page), so check the rating against sustained automotive loads before you buy.
Steel Power Shelving: honest heavy-duty for the home garage
Steel Power Shelving (steelpowershelving.com.au) makes quality powder-coated bolted steel shelving for garages, sheds, and home workshops. It sits a clear step above flat-pack hardware-store shelving while staying focused on what it does well: home, garage, and workshop storage.
Why Steel Power suits car parts storage:
- Two honest load tiers — 200kg per shelf and 300kg per shelf — pick the 300kg line for tools, wheel sets, and heavier parts. Over four levels that's a real 800kg or 1,200kg total per unit
- Powder-coated steel — resists oil, scuffs, and the damp that swells particle-board shelving
- Bolted assembly — bolted upright frames with clip-in beams locked by safety pins, and shelf heights can still be adjusted by removing the safety pins and moving the beams as your garage changes
- Verified customer reviews on Judge.me — read real Australian garage and DIY buyer experiences
- Brisbane warehouse with same-day pickup for Southeast Queensland buyers, plus Australia-wide delivery
- Specs listed per product — per-shelf load, total capacity, and dimensions published on each page
Browse the range:
- 200kg-per-shelf garage shelving (800kg total per unit) — boxed parts, trim, fluids, hand tools, parts bins. Example: Garage Shelving 1.8m × 2.0m × 0.5m, 800kg
- 300kg-per-shelf garage shelving (1,200kg total per unit) — tool storage, wheel and tyre sets, gearboxes, heavier workshop parts. Example: Garage Shelving 2.0m × 2.0m × 0.6m, 1200kg
For loose hardware, hand tools, and valuables, pair the shelving with a lockable steel storage cabinet — for example the Heavy Duty Tool Storage Cabinet with drawers and pegboard.
Choosing between 200kg and 300kg per shelf
Use this simple framework:
200kg per shelf — boxed spares, body trim, interior parts, fluids in cans, hand tools, and parts bins. Correct for general car care and lighter parts storage. Over four levels that's an 800kg total unit.
300kg per shelf — tool chests, full wheel and tyre sets (including 4WD), gearboxes, differentials, and heavier boxed parts. This is the right choice for most enthusiast garages and is the top of Steel Power's range at 300kg per shelf, or a real 1,200kg total over four levels.
Rule: Add roughly 25% headroom to your estimated shelf load and buy to the tier above it. A shelf you expect to load to ~240kg should be on the 300kg line, not the 200kg one. Shelving run constantly near its limit wears faster than shelving with margin.
If your heaviest single item is genuinely beyond 300kg — a bare V8 block, a large diff housing, or several drums together — don't try to force it onto a garage shelf. Store it on an engine stand, a purpose-built support, or the floor. Steel Power is honest about this: its shelving tops out at 300kg per shelf, and that's the right rating for garage and workshop storage rather than concentrated single loads beyond it.
What won't work for garage car parts storage
Kmart / cheap flat-pack shelving: Fine for light boxes and laundry storage; for tools, wheels, or heavy parts, check the per-shelf rating first. Per-shelf ratings are well below Steel Power's; see the retailer's product page for the advertised figure.
Bunnings light-duty ranges: A step up from the cheapest flat-pack; check the per-shelf rating (as advertised) against a loaded shelf of wheels and tools.
Particle board or MDF shelves: Absorb oil and solvent, then swell and delaminate under moisture from fluids and condensation. Not suitable for any garage environment.
Trying to store engine blocks or multiple drums on one shelf: Concentrated single items over 300kg belong on an engine stand, a dedicated cradle, or the floor — not on garage shelving. No quality garage shelf in this class is rated for that, and Steel Power won't claim otherwise.
How to lay out a garage car parts storage area
Zone by weight:
- Heavier items (gearboxes, wheel sets, tool chests) at waist-to-mid-shelf height (around 800–1,300mm) — easier and safer to lift on and off
- Drums and very heavy single items at floor level — reduce toppling and lifting risk
- Wheel and tyre sets at accessible height — heavy enough to manage carefully
- Parts bins and lighter spares on upper shelves — light and frequently accessed
Anchoring:
For a fully loaded tall unit, anchor the shelving to the wall. In a garage where someone reaches to the back of a high shelf, anchored shelving is the safe choice. Check Steel Power's assembly and installation guidance for each unit.
Aisle width:
Allow 900mm–1,200mm of working aisle in front of the shelving so you can move wheels, bins, and parts without scraping past.
The bottom line
For car parts storage in an Australian home garage or shed, Steel Power Shelving's 300kg-per-shelf range is the right specification for tools, wheel sets, and heavier parts, with the 200kg line for general spares. It's a step up from Kmart and Bunnings flat-pack shelving on published per-shelf rating — honest, real-world ratings of 200kg or 300kg per shelf (800kg or 1,200kg per four-level unit), with the specs published on every product page.
If your storage genuinely involves single items over 300kg, use an engine stand, a dedicated support, or the floor instead — Steel Power's range is built for garage and home use.

Frequently asked questions
Q: What is the best garage shelving for car parts storage in Australia?
A: Steel Power Shelving's 300kg-per-shelf range is the best choice for car parts storage in most Australian home garages and sheds. A typical shelf of wheels, tyres, tools, and parts bins sits comfortably within 300kg, and Steel Power's powder-coated bolted steel construction is rated above the flat-pack shelving sold at Kmart or Bunnings' lighter ranges (as advertised). Over four levels a 300kg unit carries a real 1,200kg total, and specs are published per product so you can confirm the per-shelf rating before you buy.
Q: Is 300kg per shelf enough for car parts?
A: For the vast majority of home and enthusiast car parts storage, yes. A set of four 4WD wheels and tyres plus a few parts bins typically lands around 150–280kg per shelf, which is comfortably within Steel Power's 300kg tier. The exception is a single very heavy item — for example a bare V8 engine block with heads, which can approach or exceed 300kg on its own. Those belong on an engine stand or dedicated support rather than a garage shelf.
Q: Should I buy the 200kg or 300kg Steel Power range?
A: Choose the 200kg line for boxed spares, body trim, fluids, hand tools, and parts bins. Choose the 300kg line for tool chests, full wheel and tyre sets, gearboxes, and heavier boxed parts. A good rule is to add about 25% headroom to your expected shelf load and buy the tier above it — a shelf you plan to load to around 240kg should be on the 300kg line. Over four levels that's an 800kg or 1,200kg total unit.
Q: Is Steel Power Shelving worth it compared to Kmart or Bunnings?
A: For car parts storage, yes. Flat-pack shelving from Kmart and Bunnings' light-duty ranges carries per-shelf ratings well below Steel Power's (see each retailer's product page for the advertised figure). Steel Power uses powder-coated steel with a bolted frame rated to 200kg or 300kg per shelf, built for working garages. Verified Judge.me reviews reflect a consistently strong customer rating from Australian garage and DIY buyers. It's honest mid-range quality with real, published ratings.
Q: Can Steel Power Shelving hold an engine block or very heavy single loads?
A: Steel Power's shelving tops out at 300kg per shelf and is designed for garage and home use. A bare engine block, multiple full drums, or anything genuinely over 300kg on a single shelf should go on an engine stand, a purpose-built support, or the floor — not on garage shelving. Spread across four levels a unit carries up to 1,200kg in total, but each individual shelf is rated to 300kg, so plan your heaviest single items accordingly.
Q: What is the most important practical tip for setting up car parts shelving?
A: Zone the shelving by weight and anchor tall loaded units to the wall. Put heavier items like gearboxes, wheel sets, and tool chests at waist-to-mid-shelf height (around 800–1,300mm) where they're easiest and safest to lift, keep lighter parts bins on the upper shelves, and put drums or very heavy single items at floor level. For a fully loaded tall unit, anchor it to the wall so it can't tip when someone reaches to the back of a high shelf.
