What is longspan shelving?
Longspan shelving is heavy-duty steel shelving for wide, bulky and heavy items that are loaded by hand: storage tubs, cartons, tools, spare parts, camping gear and stock. Compared with a single shelving unit, a longspan run gives you long, continuous shelf levels along a wall, so one run can do the job of two separate units without a gap between them.
Each Steel Power longspan run is two bays side by side on three upright frames, with four adjustable shelf levels running the full length. You can see this layout in the product photos, and it is why the listings give a load figure for each shelf level as well as a total for the whole run.
Steel Power longspan shelving sizes and prices
Every model below is 0.6m deep, black powder-coated steel with four shelf levels, and all but the 1.8m × 2.4m run list a 1-year warranty on the product page. The assembled length is a little under the nominal size (for example, the 4.0m runs measure 3.92m assembled), so check your wall against the assembled figure.

How to read the 600kg and 2400kg figures
The 2400kg figure is the total for the whole run: four shelf levels at 600kg each, evenly distributed. Because each level spans both bays, a level is made up of two shelf panels side by side, one in each bay. One listing in the range describes the same load as about 300kg per shelf, which is the 600kg level split across its two panels.
- Spread the load along the level. Put roughly half of a level's load in each bay rather than stacking it all at one end.
- Heaviest items on the lowest level. It keeps the run stable and saves lifting heavy items overhead.
- Ratings assume an even spread. A single heavy item resting in the middle of one panel is not the same as an evenly distributed load, so check the product page before storing machinery or engine parts.
- Two models are rated differently. The 2.0m-high 3.6m run and the workbench combos are listed at 300kg per shelf and 3000kg in total, so plan those to 300kg per shelf.
For more on why the per-shelf figure matters more than the total, see how much weight garage shelving can actually hold.
Longspan workbench combos (3.6m to 6.0m)
The longspan workbench combos join two shelving bays with an integrated workbench surface, so one wall gets heavy-duty storage and a place to work. They are listed at 300kg per shelf and 3000kg in total, with four shelves per bay, 0.6m deep, in 1.8m and 2.4m heights.
| Length (nominal) | Assembled length | 1.8m high (as at 13/11/2026) | 2.4m high (as at 13/11/2026) |
|---|---|---|---|
| 3.6m | 3.44m | $400 | $460 |
| 3.9m | 3.74m | $430 | $470 |
| 4.2m | 4.04m | $460 | $510 |
| 4.4m | 4.24m | $440 | $480 |
| 4.5m | 4.34m | $470 | $520 |
| 5.0m | 4.84m | $480 | $530 |
| 5.2m | 5.04m | $500 | $550 |
| 5.5m | 5.34m | $510 | $560 |

How to choose a longspan run
1. Length: measure the wall, then use the assembled figure
Measure the clear wall length, allowing for door frames, power points and any downpipe or meter box. Then pick the longest run whose assembled length fits, not its nominal length: a 3.5m run measures 3.42m assembled and a 3.2m run 3.12m.
2. Height: 1.8m, 2.0m or 2.4m
A 2.4m run gives the most storage for its floor area, but check the clearance under the ceiling, garage door tracks and the door motor before you choose it, and keep the top level for lighter items. A 1.8m run keeps every level within easier reach and suits lower ceilings.
3. Depth: 0.6m
All longspan models are 0.6m deep. Measure your largest tubs, cartons or tool cases; anything deeper than 0.6m will overhang the front or back of the shelf.
4. One longspan run or separate units?
A longspan run suits a clear stretch of wall where you want continuous levels. If you need to work around a window or door, or want different heights side by side, single bays from the shelving range may fit better. Our guide to planning 3m, 4m and 6m shelving runs covers longer walls.
5. Extending later
The product pages list compatible add-on kits in 1.2m, 1.5m and 2.0m lengths. Before ordering one, contact Steel Power with the model you have so the kit matches your run's height and depth.
Longspan vs standard garage shelving
| Standard garage shelving unit | Longspan run | Longspan workbench combo | |
|---|---|---|---|
| Length | 1.2m, 1.5m or 2.0m single bay | 2.4m to 4.0m (two bays) | 3.6m to 6.0m |
| Depth | 0.5m or 0.6m | 0.6m | 0.6m |
| Load rating (from the product pages) | 200kg or 300kg per shelf, depending on the model | 600kg per shelf level; 2400kg total (most models) | 300kg per shelf; 3000kg total |
| Price (as at 13/11/2026) | From $99.99 | From $320 | From $400 |
| Best for | One bay, tighter spaces, mixed heights | Continuous storage along one wall | Storage and a work surface on one wall |
For the full standard range, see garage shelving and our guide to choosing heavy-duty steel garage shelving.
Assembly: boltless click-in
The longspan range uses a boltless click-in system: the beams click into the slots on the upright frames and the shelf panels sit on the beams. Most of the product pages describe assembly as quick, with no tools required, and the shelf levels can be moved to suit what you store.
A loaded run is tall and heavy, so fix it to the wall or floor once it is in place, particularly at 2.4m high or where children play nearby. Our anchoring guide covers concrete floors, brick and plasterboard walls. If you would rather not assemble it yourself, see the shelving and workbench installation service page for the areas covered.
