To plan a garage storage system from scratch, work through four steps: measure your wall space and clearances, sort everything you own into zones by weight and how often you use it, match each zone to the right storage type — open steel shelving for bulky and frequently used items, lockable cabinets for tools, chemicals and valuables — and then buy units whose published load ratings actually cover your heaviest shelf. Done in that order, you buy once and the layout still works years later. Done in reverse — buying units first, then trying to make the garage fit — you end up with wasted corners and overloaded shelves.
This guide walks through each step with the practical details that trip people up: door swings, car clearance, shelf depth, and the difference between a 200kg and a 300kg per-shelf rating.
Step 1: Measure the garage properly
Grab a tape measure and note down more than just wall length:
- Wall runs. Measure each usable wall section between obstructions — meter box, window, door frames, taps.
- Ceiling height. Steel shelving units commonly come in 1.8m, 2.0m and 2.4m heights; check you have clearance, including under garage door tracks and motors.
- Depth you can give up. Shelving lines typically run 0.5m or 0.6m deep. With a car parked inside, confirm you can still open its doors and walk past. Mark the footprint on the floor with masking tape before you commit.
- Access path. Measure the door or roller opening you will carry units through, and note power points you should not block.
Step 2: Zone your gear by weight and frequency
Empty shelves do not organise a garage — zoning does. Sort everything into rough groups along two axes: how heavy it is, and how often you reach for it.
| Zone | Typical contents | Best position |
|---|---|---|
| Heavy + frequent | Toolboxes, drums of consumables, machinery | Waist-height shelves, strongest units |
| Heavy + rare | Spare parts, dense boxed items | Bottom shelves |
| Light + frequent | Hand tools, tape, fasteners, cleaning gear | Eye-level shelves or cabinet tops |
| Light + rare | Holiday decorations, empty eskies, camping bags | Top shelves |
| Secure zone | Power tools, chemicals, anything valuable or child-unsafe | Lockable steel cabinet |
The golden rules: heavy items live low, frequently used items live between waist and eye level, and anything you would not want stolen — or found by kids — goes behind a locked door.
Step 3: Match zones to storage types
Open steel shelving: the workhorse
Open shelving handles the bulk of a garage: tubs, boxes, sporting gear, garden supplies, parts bins. Steel Power Shelving's garage shelving range comes in two clearly rated lines, and picking between them is the key planning decision:
- Light-duty line — 200kg per shelf, 800kg total per unit (four load-bearing shelves), 0.5m deep. Suits household overflow, tubs, camping and sporting gear.
- Heavy-duty line — 300kg per shelf, 1,200kg total per unit, 0.6m deep, powder-coated steel with height-adjustable shelves, in 1.8m, 2.0m and 2.4m heights and 1.5m and 2.0m widths. Suits tools, parts and dense boxed loads.
Both ratings assume an evenly distributed load. Estimate your heaviest planned shelf and leave a margin; if any single shelf will regularly sit near 200kg, plan the heavy-duty line for that wall from the start.
Lockable steel cabinets: the secure zone
For power tools, chemicals and anything valuable, a lockable steel cabinet does what open shelving cannot: it controls access and keeps dust off. The metal cabinet range includes lockable cabinets with adjustable shelves and taller wardrobe-style units; full dimensions and shelf details are on each product page. In most garages one cabinet next to a run of shelving covers the secure zone completely.
Don't forget the workspace
If you actually work in the garage — rather than just storing in it — leave one wall section for a workbench with shelving above or beside it, and keep that bench clear of the storage zones so projects do not creep across every surface.
Step 4: Lay it out and sanity-check
- Draw the plan. Even a rough sketch with measurements catches clashes — a cabinet door that hits a car mirror, a 2.4m unit under a 2.2m door track.
- Put the heavy-duty shelving where the weight is. Mixing lines is normal: heavy-duty on the tool wall, light-duty for household overflow.
- Leave one empty shelf. Garages accumulate. A spare shelf per unit is the cheapest future-proofing there is.
- Check assembly and delivery details on each product page, and if you are in Brisbane, same-day pickup from the Willawong warehouse means you can plan on the weekend and build the same weekend.

FAQ
Q: What is the first step in planning garage storage?
A: Measure before you buy anything: usable wall runs, ceiling height including door tracks, the depth you can give up while still parking a car, and the access path for carrying units in. Shelving commonly comes in 1.8m, 2.0m and 2.4m heights and 0.5m or 0.6m depths, so these measurements decide your options.
Q: Should I choose shelving or cabinets for a garage?
A: Usually both. Open steel shelving is the workhorse for bulky, frequently accessed items like tubs, boxes and parts bins, while a lockable steel cabinet secures power tools, chemicals and valuables. A common layout is one cabinet beside a run of shelving sized to the wall.
Q: How do I decide between 200kg and 300kg per shelf?
A: Estimate the heaviest single shelf in your plan. The light-duty line (200kg per shelf, 800kg per unit) covers household storage; the heavy-duty line (300kg per shelf, 1,200kg per unit) covers tools, parts and dense boxes. Ratings assume an evenly distributed load, so leave a comfortable margin rather than planning to the limit.
Q: Where should heavy items go on garage shelving?
A: On the bottom shelves. Keeping the heaviest items low makes the unit more stable and safer to load and unload. Frequently used items belong between waist and eye level, and light, rarely used gear goes up top.
Q: How deep should garage shelving be?
A: The two common depths are 0.5m and 0.6m. Steel Power Shelving's light-duty line is 0.5m deep and the heavy-duty line is 0.6m deep, which gives bulkier workshop items more room to sit squarely. Check car door clearance before choosing the deeper units on a parking wall.
Q: Can I mix shelving lines in one garage?
A: Yes, and it is often the smartest plan: heavy-duty 300kg-per-shelf units on the tool and parts wall, light-duty 200kg-per-shelf units for household overflow. You pay for load capacity only where you need it, and both lines are listed with published per-shelf ratings on their product pages.
