A guide to cantilever racking for long/bulky goods: pipe, timber, steel sections, panels — upright/arm/brace structure, straight vs inclined arms, capacity per arm, single/double-sided, standards FEM 10.2.09 / AS 4084 / RMI, and selection in Thailand.
"Long" and "bulky" goods — steel/PVC pipe, sawn timber, steel bar, structural sections (H-beam, channel), boards/metal sheet, aluminium profiles — cannot go on standard pallet racking. Stacked on the floor they waste space, are hard to pick, and get damaged.
Cantilever racking is the answer — designed specifically for long goods. This article explains the structure, arm selection, capacity, and the standards used.
1. Structure — Three Main Parts
flowchart TD A[Cantilever Rack] --> B[Upright/Column
vertical column + floor-bolted base] A --> C[Arm/cantilever
straight or inclined] A --> D[Brace Set
ties columns together] B --> E[Choose by: weight + length of goods] C --> E D --> E E --> F[single or double-sided]
- Upright (column + base) — load-bearing column; the long base resists overturning + floor anchors
- Arm (cantilever) — holds the goods, height-adjustable, no front beam = easy long-item loading
- Brace set — ties columns into a row
Arranged single-sided (against a wall) or double-sided (mid-warehouse, used from both sides).
2. Straight vs Inclined Arms
| Arm type | Best for |
|---|---|
| Straight | sawn timber, panels, boxes — non-rolling goods |
| Inclined | pipe, round bar — tilted up to prevent rolling off the front |
Specify the stored goods up front — round pipe always needs inclined arms, or it rolls off.
3. Capacity — Three Levels
- Per arm — depends on arm length + steel section (longer = lower)
- Per upright — the sum of arms on the column
- Whole system + overturning — the row's tipping stability
Don't just read the "maximum number" in a catalog — state the real weight + length + load positions for the engineer to calculate.
4. Design Standards
| Standard | Origin |
|---|---|
| FEM 10.2.09 | Europe — cantilever racking specifically |
| AS 4084 | Australia — steel storage racking |
| RMI ANSI MH16.1-2023 | USA |
| SS 2643 (INSTA 253) | Sweden/Nordic |
| DPT 1311-50 | Thailand — regional seismic forces |

5. Checklist Before Ordering Cantilever Racks
- State the stored goods — type (pipe/timber/steel), length, weight per piece
- Choose arms — straight (non-rolling) / inclined (round pipe)
- single vs double-sided by floor space
- Handling method — forklift / crane → sets the clearances
- Bangkok → consider seismic + engineer-certified drawings for acceptance
We design and supply cantilever racking for all long goods (pipe, timber, steel bar, sections, panels) to FEM 10.2.09 / AS 4084 / RMI — with straight/inclined arms matched to the goods, capacity calculation per arm/column/system, seismic support to DPT 1311, and engineer-certified drawings for government/inspection-acceptance work.

Summary
- Cantilever racking = cantilevered-arm racking (no front beam) for long/bulky goods that won't fit pallets
- Three parts: upright + arm + brace · single/double-sided
- Straight arms (non-rolling) vs inclined arms (round pipe — anti-roll)
- Capacity at three levels: per arm · per column · whole system + overturning
- Standards: FEM 10.2.09 / AS 4084 / RMI + seismic DPT 1311 (Bangkok)
Correctly designed cantilever racking = safe long-goods storage, space saved, fast picking, no toppling.
