Four metres of wall. Eight shelves. Sixteen hundred kilograms of capacity. Two matching black steel racks.
Most serious garages and workshops need more than a corner shelf unit - they need a run of matched, heavy-duty storage that actually covers a full wall and holds what a working space actually accumulates. This Giantz warehouse rack set delivers two identical steel rack units that install side by side to create a continuous 4-metre wall of 200kg-per-shelf storage, reaching 2.4 metres high in matte black powder-coated steel. It's the kind of shelving that makes a garage feel like a proper workshop.
Why two racks, not one big one.
Shipping a single 4-metre-wide steel rack across Australia is impractical - cartons that size get damaged in transit and require freight lifts to handle. Two matched 2m units solve this elegantly: each arrives as a manageable carton, assembles independently, and then positions side by side with the shared upright posts creating a continuous visual and structural run. The result looks like one installation. Each unit is structurally independent, which also means you can position them in an L-shape or separate zones if your space suits that better.
2.4 metres tall - the detail that matters for a serious workshop.
The Big W and Woolworths versions of this Giantz rack are 2.0 metres tall. This version reaches 2.4 metres - an extra 40 centimetres that creates a full additional shelf level or gives you head clearance for standing storage items that 2m racks can't accommodate. In a standard 2.7m garage ceiling, a 2.4m rack uses the vertical space efficiently without the ceiling becoming a constraint. If you're storing long-handled tools, pipe sections, timber lengths, ladders or anything tall, this extra height matters.
- 📐 2 matching rack units - 4m combined wall coverage when installed side by side
- 📏 2.4m tall - 40cm taller than standard versions - more shelf levels, more vertical storage for standing items
- 📦 60cm deep shelves - 10cm deeper than standard versions; accommodates larger tubs, equipment and sheet goods
- ⚖️ 200kg per shelf, 4 tiers per rack - 800kg per unit, 1,600kg total across both
- 🔩 Z-bracing on every unit - diagonal cross-members prevent the rack from racking (lateral movement) under asymmetric or shifting loads
- 🏗️ All-steel construction - no MDF boards - shelves, frame, bracing all steel; no moisture or humidity concerns in any garage environment
- 🔐 16 safety plugs included - beam-to-upright locking pins; 8 per unit; prevent beam displacement under vibration or impact loading
- 📏 Adjustable shelf heights - reposition tiers to suit different load heights without disassembling the frame
- 🎨 Powder-coated matte black finish - rust-resistant; the industrial black aesthetic that distinguishes a real workshop setup
What Z-bracing does - and why it matters.
Z-bracing refers to diagonal cross-members fitted to the rear of each rack unit in a Z or X pattern. Without bracing, a loaded rack can experience "racking" - where the frame gradually shifts sideways under asymmetric load, vibration or impact, eventually causing collapse. Z-bracing prevents this by triangulating the frame. It's not a luxury feature - it's standard practice on any industrial shelving designed to hold significant weight over years of regular loading and unloading. The 16 safety plugs complement this by locking the horizontal beams at each connection point, preventing any vertical displacement of a loaded shelf.
Practical load guide per shelf (200kg capacity):
Automotive
Engine block (120–180kg), gearbox + diff (80–120kg), 4 tyres + rims (60–80kg), battery collection, full fluid stock.
Trade Materials
Bulk hardware (bolts, fittings), plumbing supplies, electrical conduit stock, full boxes of tiles or pavers.
Workshop Equipment
Heavy power tools, compressor + hose, welding gear, full toolboxes and roller cabinets positioned alongside.
Storage & Seasonal
Large IBC totes, multiple 60L bins fully loaded, camping and outdoor gear, archived filing, bulk food storage.
Where this fits in the SmartStorage.au workshop shelving range.
If you're coming from home garage shelving (Giantz boltless 1.5m units, 150kg per shelf with MDF boards), this is the step up to all-steel 200kg construction with serious wall coverage. If you need a formally expandable system that can grow to 8m+ in an ongoing commercial or trade operation, the Centurion LS-200 long span shelving with gusseted joints and floor-bolt capability is the next tier. This Giantz 4m warehouse rack sits confidently in the middle - maximum coverage, maximum value, genuine industrial construction.
Assembly. Two racks assemble independently. The assembly method uses a rubber mallet to tap horizontal beams into the upright slots - no tools required for the primary assembly. Fitting the 16 safety plugs is done by hand. Allow approximately 45–60 minutes per unit, or 90 minutes total working with two people. Position both units before final tightening if you're installing them side by side - this lets you check the combined alignment before committing. The instructions cover this clearly.
