In a warehouse or logistics area, knowing how much weight a pallet rack can support is crucial to ensuring the safety of operators and the durability of the installation. This question often comes up when planning a warehouse, especially when handling heavy pallets with forklift trucks.
In this article, we explain the factors that determine the maximum load, the standards to be met and how Mecalux solutions guarantee safety and performance.
What is a pallet rack?
A pallet rack is a type of metal shelving designed to store complete pallets, often in industrial warehouses or distribution centres.
Unlike light shelving, it can be several metres high and support very heavy loads, making it an essential solution for heavy logistics flows.
Pallet rack load: definition
The load on a pallet rack is generally defined in two ways:
- Load per level (or pallet level)
- This is the maximum weight that a single shelf in the rack can support.
- Example: a shelf can support 1,000 kg per level.
- Total rack load
- This is the sum of the charges for all levels combined.
- Example: a 5-level rack with 1,000 kg per level will have a total load of 5,000 kg.
What factors influence load capacity?
Several factors determine how much weight a pallet rack can support:
1. The quality and thickness of the steel
Racks made from high-strength steel (like those from Mecalux) can withstand heavier loads than less robust structures.
2. Rack height and depth
The higher the rack, the greater the lateral and vertical forces, which can limit the maximum load per level.
3. Width between uprights
A wide span supports less weight per level than a narrow span, because the bending forces are greater.
4. Load distribution
An incorrectly positioned pallet or weight distribution can significantly reduce rack capacity and create a risk of tipping.
5. Fixing to the floor
The racks must be fixed to the floor with anchor plates to guarantee their stability and be able to support their rated load.
Standards and load calculations
In Europe, pallet racks must comply with a number of standards:
- EN 15620: permissible deformation limits for shelving.
- EN 15629: installation instructions to ensure that the rated load is complied with.
- EN 15635: rules for the safety and periodic inspection of racks.
Each manufacturer, like Mecalux, provides a certified load table showing the maximum load per level and per bay, calculated according to height, depth and type of floor.
Examples of loads for different racks
| Type of rack | Load per level | Total load (example 5 levels) |
|---|---|---|
| Lightweight rack | 300-500 kg | 1,500-2,500 kg |
| Standard rack | 1,000-1,500 kg | 5,000-7,500 kg |
| Heavy rack | 2,000-3,000 kg | 10,000-15,000 kg |
| Very heavy / industrial rack | 4,000-6,000 kg | 20,000-30,000 kg |
Note: These values are indicative. The exact load must always be calculated according to the manufacturer and the specific characteristics of the site.
Good practice in respecting maximum load
- Never exceed the load specified by the manufacturer.
- Distribute the load evenly on the pallet and on the level.
- Check the condition of the rack regularly: no loose bolts, no unrepaired shocks.
- Train staff to place pallets correctly.
- Avoid modifying the rack without technical approval, especially for heavy or very high racks.
Why choose Mecalux?
Mecalux pallet racks are renowned for their robustness and reliability:
- Design certified to European standards.
- Modular capacity: several levels and depths to suit requirements.
- Quality materials: high-strength steel and optimised anchor plates.
- Full support: technical study, installation, training and maintenance.
Thanks to these advantages, you can be sure that your rack will safely support its intended load, even in demanding logistics environments.
Conclusion
The load capacity of a pallet rack depends on a number of factors: quality of the material, height, width, load distribution and fixing to the floor.
Compliance with the maximum load specified by the manufacturer is essential to guarantee the safety of operators and the longevity of the installation.
