Load capacities, safety standards, installation tips, and how to avoid costly mistakes
Heavy duty pallet racking is the backbone of modern warehouse storage. Whether you're managing a distribution center, manufacturing facility, or cold storage operation, choosing the right system directly impacts your safety, efficiency, and bottom line.
In this guide, we break down everything you need to know — from load capacity calculations to installation best practices — so you can make an informed decision.
Heavy duty pallet racking (also called selective pallet racking) gives you 100% direct access to every pallet position — no need to move other loads to reach the one you need. This makes it the most versatile and widely-used racking system worldwide.
Quick Take: If you store a wide variety of SKUs, need frequent access, or operate in a FIFO (first-in-first-out) environment, heavy duty selective racking is your best starting point.
Load capacity is the single most important specification. Here's how different profiles compare:
| Upright Profile | Beam Size | Load per Level | System Height | Best For |
|---|---|---|---|---|
| 80×80 mm | 100×50 mm | 500 – 1,000 kg | Up to 6m | Light industrial storage |
| 90×70 mm | 120×50 mm | 1,000 – 2,000 kg | Up to 8m | General warehouse |
| 100×70 mm | 140×50 mm | 1,500 – 2,500 kg | Up to 10m | Heavy goods distribution |
| 120×95 mm | 160×50 mm | 2,000 – 4,000 kg | Up to 12m+ | Industrial / bulk storage |
⚠️ Critical: Never exceed the rated capacity shown on your load placard. Overloading is the #1 cause of racking failures and warehouse accidents.
Heavy duty pallet racking works across many industries. Here are the most common setups we see:
Typical setup: 80×80 or 90×70 uprights, 2,000 kg/level, 4–6 levels high, with wire decking for smaller cartons. FIFO layout for perishable goods.
Typical setup: Hot-dip galvanized finish to prevent corrosion in sub-zero environments. 100×70 uprights for high-density layouts, minimizing floor space to reduce energy costs.
Typical setup: 120×95 uprights, 3,000–4,000 kg/level, heavy-duty beams (160×50 mm). Column guards and load locks are essential in high forklift traffic areas.
Typical setup: Mixed configurations — heavy duty for bulk reserve storage, combined with medium duty shelving for pick faces. Wide aisle widths (3.5m+) for efficient forklift movement.
Proper installation is critical for safety and performance. Here's the standard process:
Verify floor flatness (FF/FL numbers), load-bearing capacity, and levelness. Floor tolerance should be within ±3mm over 3 meters.
Use laser levels and chalk lines to mark upright positions. Verify all dimensions against the engineering drawing before drilling.
Use correct anchor bolts (typically M12 or M16 chemical or wedge anchors). Torque to manufacturer specifications.
Install uprights plumb (within 3mm per 3 meters of height). Use temporary bracing until the full frame is connected.
Start from the bottom level and work upward. Ensure all load locks are fully engaged before loading.
Check all connections, verify plumb and level, and install load capacity placards at each bay.
💡 Pro Tip: Always follow the manufacturer's installation manual. Improper installation can reduce load capacity by up to 40%.
The most common and most dangerous. Always calculate your heaviest pallet + 10% buffer, then select a beam profile rated for that load. Never assume "it'll be fine."
Installing heavy racking on an uneven floor leads to frame distortion, uneven load distribution, and potential collapse. Always conduct a floor survey first.
Aisle width should be forklift turning radius + 300mm minimum. Too narrow = frequent rack impacts. Too wide = wasted warehouse space.
Never weld, drill, or cut structural components. This voids all certifications and dramatically reduces load capacity. Use manufacturer-approved accessories only.
EN 15635 requires daily visual checks, monthly inspections by a competent person, and annual professional audits. Skipping inspections is a compliance violation and safety risk.
Your racking system must comply with recognized standards:
| Standard | Region | Covers |
|---|---|---|
| EN 15635 | Europe | Use & maintenance of storage systems |
| EN 15512 | Europe | Design of adjustable pallet racking |
| RMI / ANSI MH16.1 | North America | Rack design & load testing |
| AS 4084 | Australia | Steel storage racking design |
