Understanding how pallet racking systems are classified for freight shipping is crucial for businesses looking to manage logistics costs efficiently. When transporting industrial storage systems like metal pallet racks, one of the most important considerations is the freight class assigned to the shipment. This classification influences shipping rates, handling requirements, and delivery timelines.
In this comprehensive guide, we’ll break down the freight classification system for pallet racks, explore how it affects your shipping logistics, and explain how various types of metal pallet rack storage solutions are categorized. Whether you're shipping a heavy duty pallet racking system or a stainless steel pallet racking setup, this article will help you navigate freight classifications effectively.
Freight class is a standardized way to categorize different types of cargo based on their physical and transport-related characteristics. It’s defined by the National Motor Freight Traffic Association (NMFTA) in the United States and used by carriers to determine shipping rates. There are 18 freight classes, ranging from Class 50 (least expensive) to Class 500 (most expensive).
The classification is based on:
Density (weight per cubic foot)
Stowability
Handling
Liability
Each of these elements is considered to place items like metal pallet racks into the right category for shipping.
Typically, metal pallet racks are classified between Class 50 and Class 85, depending on the materials, design, and whether the racks are knocked down (disassembled) or fully assembled. Disassembled metal pallet rack components such as upright frames, beams, and pallet rack foot plates usually fall into a lower freight class due to better stacking and higher density.
| Component | Average Freight Class | Notes |
|---|---|---|
| Upright Frames | 50 - 60 | Long but stackable when bundled |
| Beams | 55 - 65 | Moderate size and weight |
| Pallet Rack Foot Plate | 70 - 85 | Dense and small, but often shipped in bulk |
| Fully Assembled Racks | 85 - 125 | Higher class due to odd shape and low density |
The more efficiently your metal pallet rack system can be packaged and loaded, the lower the freight class, resulting in reduced costs.
Several factors determine how a warehouse rack shipment is classified:
Packaging Efficiency: Disassembled parts stacked tightly into pallets lead to a lower freight class.
Material Type: Stainless steel pallet racking may be heavier and more expensive to ship than standard carbon steel.
Customization: Unique sizes or shapes may increase the freight class.
Finish and Coating: Protective coatings for corrosion resistance, such as in stainless steel pallet racking, can impact handling.
It’s important to communicate clearly with your pallet racks manufacturer to determine how best to ship your racks.
Lowering the freight class and overall shipping expenses is possible with a few strategic approaches:
Order in Bulk: Larger quantities often allow for better stacking and efficient packaging.
Use Knocked-Down Kits: Disassembled shipments take up less space and are easier to handle.
Standardize Sizes: Consistent sizes across racks reduce the freight class.
Coordinate with Your Manufacturer: A reliable pallet racks manufacturer like Fenghui logistics can recommend the best shipping configuration.
Choosing the right type of metal pallet rack can influence your logistics costs. Here's a look at how different systems stack up:
| System Type | Freight Class Range | Shipping Complexity |
| Heavy Duty Pallet Racking System | 60 - 85 | Heavier, bulkier parts |
| Standard Metal Pallet Rack | 50 - 65 | Easier to stack and ship |
| Stainless Steel Pallet Racking | 65 - 85 | Heavier material, may increase class |
If you're aiming for efficiency in storage and shipping, standard metal pallet rack storage is often the most cost-effective solution.
Freight classification is just one part of the puzzle. Warehouse managers and logistics planners should also consider:
Warehouse layout compatibility: Choose racks that optimize space and reduce the need for custom shapes.
Modular designs: Systems like those offered at Fenghui logistics's product range make scaling up easier without logistical complications.
Durability vs. Weight: Heavier systems last longer but cost more to ship. It’s a trade-off worth evaluating.
Some warehouse professionals mistakenly believe that all metal pallet racks fall under the same freight class. In reality, minor differences in materials, finishes, and packaging methods can significantly shift the classification.
Another myth is that lighter always means cheaper. While low-density items weigh less, they often occupy more space, which increases the freight class. That's why disassembled metal pallet rack components are typically preferred.
The right manufacturer doesn’t just build storage; they support your logistics. When choosing a pallet racks manufacturer, prioritize:
Freight expertise: Companies that understand NMFC codes can help reduce your freight class.
Flexible packaging options: Fenghui logistics, for example, offers modular metal pallet rack storage solutions that are easy to transport.
Documentation support: Accurate shipping descriptions prevent reclassifications and added fees.
Proper freight packaging ensures lower costs and prevents damage. Most metal pallet rack systems are packed using:
Shrink wrapping: Protects metal from moisture and abrasions.
Steel strapping: Keeps components tightly bundled.
Palletized shipments: Enhances stacking efficiency.
Labeled components: Improves inventory checks upon delivery.
Heavy duty pallet racking systems may also include reinforced bracing or edge protection to withstand long-distance travel.
Density is calculated by dividing the weight by cubic feet of the shipment. A high-density load results in a lower freight class. Here’s a quick density comparison:
| Rack Type | Average Density (lbs/ft³) | Freight Class Estimate |
| Knocked-Down Metal Rack | 25-35 | Class 55-60 |
| Assembled Rack | 8-12 | Class 85-100 |
| Stainless Steel System | 20-30 | Class 65-75 |
This illustrates why knocked-down kits are not only easier to ship but more economical.
Higher freight classes often mean higher cost and potentially slower delivery. That’s because:
High-class items require special handling.
They may not be consolidated with other loads.
Carriers prioritize dense, stackable freight for efficiency.
By reducing the freight class of your metal pallet rack shipment, you often get faster and more reliable delivery.
Q1: What is the freight class of a standard metal pallet rack?
A1: It typically falls between Class 50 and Class 65, depending on how it's packaged and its material density.
Q2: Does stainless steel pallet racking have a higher freight class?
A2: Yes, because it's denser and often heavier, stainless steel pallet racking may fall into a slightly higher class than carbon steel systems.
Q3: How can I reduce shipping costs for pallet racks?
A3: Use knocked-down components, standard sizes, and work with an experienced pallet racks manufacturer for optimal packaging.
Q4: Why does packaging matter in freight classification?
A4: Well-packaged metal pallet rack components take up less space, increasing density and reducing the freight class, which cuts shipping costs.
Q5: Are pallet rack foot plates included in freight class calculations?
A5: Yes. These are dense components and affect both the overall weight and classification, especially if shipped in bulk.
Q6: Can I ship fully assembled warehouse racks?
A6: You can, but it's not recommended due to higher freight class, increased space usage, and risk of damage.
Q7: Does Fenghui logistics offer freight-efficient pallet racks?
A7: Yes. Fenghui logistics designs modular metal pallet rack storage systems that are easy to disassemble, package, and ship at lower freight classes.
Understanding the freight class of metal pallet rack systems is critical for cost-effective and efficient logistics. From the role of density and packaging to the influence of materials like stainless steel and heavy duty configurations, every factor plays a part in how your warehouse rack is classified and shipped. Working closely with a knowledgeable pallet racks manufacturer like Fenghui logistics can ensure your pallet rack foot plate components and full systems are shipped in the most economical way possible.Choosing the right freight class doesn’t just save money—it ensures your storage systems arrive on time, intact, and ready for action.
