Managing Multi-Site Distribution With a Modern WMS
How much does flatbed shipping cost? This guide breaks down the key factors that drive flatbed rates, from equipment types and lane balance to accessorial charges and seasonal demand, and shows you how Redwood's Open 4PL approach to transportation management can help you get more accurate quotes and reduce your open-deck freight spend over time.
What Is Flatbed Shipping?
Flatbed shipping is a method of freight transportation that uses an open-deck trailer with no walls, roof, or doors. This open design lets you load cargo from the top, sides, or rear using cranes, forklifts, or other heavy equipment.
That flexibility is exactly why flatbeds exist. When your freight is too tall, too wide, or too oddly shaped to fit inside a standard dry van, a flatbed is typically your best option. Industries like construction, manufacturing, and automotive rely on flatbed shipping every day to move the materials and equipment that keep operations running.
The tradeoff is that open-deck freight requires more hands-on work. Drivers have to physically secure every load with chains, straps, or binders. And because the cargo is exposed to the elements, you may need tarping or other protective measures. All of that factors into the final cost.
What Freight Typically Ships on a Flatbed?
The type of commodity you are moving has a direct impact on your rate. Carriers price flatbed loads based on weight, dimensions, and how much effort it takes to secure the freight safely.
Common flatbed freight includes:
- Lumber, steel beams, rebar, and concrete forms
- Manufacturing equipment, agricultural machinery, and industrial presses
- Prefabricated trusses, large pipe, and commercial HVAC units
- Wind turbine components, modular buildings, and oversized vehicles
If your freight has unusual dimensions or requires specialized handling, expect the cost to go up. A standard pallet of lumber is straightforward. A 60-foot steel bridge girder is not.
Flatbed Trailer Types That Affect Shipping Cost
Not every flatbed trailer is priced the same. The configuration you need depends on your freight's height, weight, and loading requirements, and each type carries a different rate expectation based on availability and specialization.
| Trailer Type | Best For | Cost Implication |
|---|---|---|
| Standard flatbed (48 or 53 feet) | General oversized freight, palletized goods | Baseline rate |
| Step deck (drop deck) | Taller freight exceeding standard height limits | Moderate premium |
| Double drop or RGN | Extremely tall or heavy machinery needing ground-level loading | Higher premium |
| Conestoga | Freight needing weather protection without full enclosure | Moderate premium |
| Hotshot | Smaller, time-sensitive loads under full truckload size | Variable, often expedited pricing |
Choosing the right trailer from the start helps you avoid rejected loads and rebooking fees. If you are unsure which configuration fits your freight, providing detailed dimensions and photos to your logistics partner will help them match you to the right equipment.
Average Flatbed Shipping Cost Per Mile
Most shippers want a simple answer here, and the general range for flatbed freight falls between $2.50 and $3.50 per mile. But that range can swing significantly depending on market conditions, fuel costs, and how much flatbed capacity is available in your region.
You will typically see two pricing structures when booking flatbed freight:
- Spot rates: Negotiated on a per-shipment basis, reflecting real-time supply and demand. These fluctuate daily.
- Contract rates: Pre-negotiated for consistent lanes and volumes, offering more predictable pricing over weeks or months.
Many shippers use a blend of both. Contract rates cover your steady, repeatable lanes, while spot rates fill in the gaps when volumes spike or you need to move freight on a lane you do not normally use. Flatbed capacity also tends to tighten during spring and summer when construction activity peaks, and the ongoing truck driver shortage adds further pressure, which pushes spot rates higher.
Flatbed Shipping Cost Factors That Change the Rate
Several variables determine whether your shipment lands at the low end or the high end of that per-mile range. Understanding these factors helps you anticipate costs before you request a quote.
Distance and lane balance
Mileage matters, but lane dynamics matter just as much. Carriers pay close attention to whether your freight moves on a headhaul lane (into a high-demand region) or a backhaul lane (returning toward the carrier's home base).
When lanes are imbalanced, carriers have to drive empty (called deadhead miles) to find their next paying load. They build that repositioning cost into your rate. If you are shipping into a rural area with little outbound freight, expect to pay more simply because the carrier knows the return trip will be unproductive.
Freight dimensions, weight, and equipment needs
Oversized or overweight loads trigger additional costs that standard shipments do not. When your freight exceeds legal dimensions or weight limits, you will need permits from each state the truck passes through. In some cases, you will also need pilot cars or escort vehicles to guide the load safely.
These requirements also restrict your routing options. Low bridges, narrow roads, and weight-restricted highways may force the carrier onto longer, less efficient paths. The more complex the move, the higher the rate.
Securement, tarping, permits, and accessorial charges
Flatbed freight requires significantly more manual labor than enclosed trailer shipping. That extra work shows up on your invoice as accessorial charges.
Common flatbed accessorials include:
- Tarping: Protecting freight from rain, dust, or debris during transit
- Strapping and blocking: Using chains, binders, or lumber to secure irregularly shaped items
- Permits: Required documentation for oversized or overweight moves
- Detention: Fees charged when loading or unloading takes longer than the allotted free time
- Special handling: Extra labor at the pickup or delivery site
Knowing which accessorials apply to your shipment before you book helps you minimize carrier accessorial charges and avoid billing surprises. Tarping alone can add a meaningful surcharge because it is physically demanding and time-consuming work for the driver.
What Information Affects a Flatbed Freight Quote?
The more precise the details you provide, the tighter your flatbed freight quote will be. Vague or incomplete information almost always leads to inflated estimates and unexpected charges after delivery.
Before requesting a quote, have the following ready:
- Origin and destination ZIP codes
- Pickup and delivery dates (or your flexibility window)
- A clear commodity description
- Exact freight dimensions (length, width, height)
- Total freight weight
- Any special requirements such as tarping, permits, or appointment scheduling
If your freight is unusual in shape or size, share photos or diagrams. Visual references help carriers understand exactly how to load and secure the item, which leads to more accurate pricing. When a truck arrives and the freight does not match what was quoted, the carrier may refuse the load entirely. That results in a Truck Order Not Used fee and leaves you scrambling for replacement capacity at a premium.
How a Modern 4PL Approach Helps Lower Flatbed Shipping Cost
When you manage flatbed freight through a single broker or handle it entirely in-house, you are often limited to a small carrier pool and a narrow view of the market. You may get a rate, but you have no way of knowing whether it is competitive or whether better capacity exists on a different network.
Redwood's Open 4PL approach solves this by combining a broad carrier network, data-driven rate benchmarking, and integrated technology into an open ecosystem. Instead of locking you into one set of carriers or one platform, this model lets you access vetted flatbed capacity across all equipment types while maintaining full visibility into your shipments.
The practical difference shows up in how freight gets priced and managed day to day. With rate benchmarking tools, you can see whether a quote reflects fair market value for that lane and equipment type. With real-time tracking and exception management, you catch problems before they become costly delays. And with technology integration through RedwoodConnect, your tendering, tracking, and invoicing all connect to the systems you already use.
Rather than quoting a single rate and moving on, a Modern 4PL partner evaluates your full freight profile, identifies where you are overspending, and continuously optimizes. If you want to understand how this model works in more detail, the Modern 4PL for Dummies guide is a good place to start. You can also explore our case studies to see how other industrial shippers have reduced their flatbed and open-deck freight costs.
Final Thoughts on Flatbed Shipping Costs
Flatbed shipping rates depend on a combination of equipment type, freight characteristics, lane balance, seasonality, and accessorial requirements. Accurate quoting starts with providing detailed, accurate shipment information to your logistics partner.
When you understand the mechanics behind these costs, you can make smarter procurement decisions and avoid the invoice surprises that eat into your margins. Partnering with a logistics provider that brings network depth, market intelligence, and technology integration turns flatbed shipping from an unpredictable expense into a manageable, optimizable part of your supply chain.

Frequently Asked Questions
How much does it cost to ship a single item on a flatbed truck?
The cost depends on the item's weight, dimensions, origin, destination, and any special handling requirements. Even a single-item shipment can vary widely, so providing exact details is the fastest way to get an accurate quote.
What is the difference between a spot rate and a contract rate for flatbed shipping?
A spot rate is negotiated per shipment based on current market conditions, while a contract rate is pre-negotiated for a set period and typically covers consistent lanes. Most shippers use a combination of both to balance cost predictability with flexibility.
When should I use a flatbed instead of a dry van?
Flatbeds are the right choice when your freight is too tall, too wide, or too heavy for an enclosed trailer, or when it needs to be loaded from the top or sides with a crane or forklift. If your cargo fits inside a dry van and does not require special loading, a dry van is usually the more cost-effective option.
How far in advance should I book flatbed freight to get the best rate?
Booking at least a few days ahead generally gives you access to better rates and more carrier options. During peak seasons like spring and summer construction months, planning further ahead helps you avoid capacity crunches and the premium pricing that comes with them.
