Flatbed and specialized freight is one of the most consistently respected niches in freight brokerage. The brokers who know it earn their margins through genuine expertise, and the relationships they build with equipment operators tend to be more durable than in dry van.
This guide explains how the segment works, what equipment types you need to know, and how brokers typically build their flatbed book.
What "Flatbed" Actually Encompasses
"Flatbed" is a shorthand that covers a range of open-deck trailer types with very different capabilities:
Standard flatbed (48' or 53'): The workhorse of open-deck freight. No walls or roof, load exposed to weather. Used for construction materials, machinery, pipes, lumber, steel coil, agricultural equipment. Maximum legal cargo height typically 8'6" above deck (less for lower deck height trailers), width 8'6", length 48–53 feet.
Step deck (drop deck): Two deck levels — a shorter upper deck near the front and a longer lower deck. Allows taller cargo (up to approximately 10'2" legal height in most states) without requiring a permit. Common for taller equipment, tall machinery, and height-sensitive cargo that won't fit a standard flatbed legally.
RGN (Removable Gooseneck / Lowboy): The lowest of the open-deck options. The front section of the trailer detaches, allowing cargo to be driven onto the deck. Used for heavy construction equipment, large machinery, and very tall or heavy cargo. Legal height from the deck typically 8'6" or more depending on deck height. Maximum weight capacity typically 50,000–80,000 lbs depending on axle configuration.
Conestoga / rolling tarp: A flatbed with a retractable hard-sided enclosure. Provides weather protection while allowing loading from the sides. Common for metal products, manufactured goods, and cargo that needs flatbed loading convenience with reefer-like weather protection.
Double-drop (extendable): Similar to an RGN but with an extendable middle section for very long cargo. Used for oversized structural steel, large industrial equipment, and other items that exceed standard trailer length.
Hotshot (flatbed pickup with gooseneck): Smaller loads moved by a pickup truck with a gooseneck flatbed trailer. Popular for urgent delivery of smaller machinery parts, construction materials, and equipment to job sites. Day-rate heavy versus standard per-mile loads.
The Commodity Mix
The commodities that move on flatbed equipment tell you who your shippers are:
Construction industry: Lumber, drywall, roofing materials, rebar, concrete pipe, excavators and construction equipment Oil and gas: Drilling equipment, pipeline sections, pump jacks, wellhead equipment Agriculture: Tractors, combines, irrigation equipment, grain bins, structural steel for farm buildings Manufacturing: Industrial machinery, steel coils, steel beams, manufactured homes and modular structures Infrastructure: Utility transformers, wind turbine components, bridge sections, power plant equipment
These industries have specific seasonality, specific loading requirements, and specific compliance needs. Brokers who understand the industries they serve — not just the trailer types — have more credible conversations with shippers.
Permitting: The Critical Complexity
The moment a load exceeds legal dimensions — more than 8'6" wide, more than 13'6" tall (varies by state), more than 53' long, or over legal weight — it requires a permit to move on public roads.
Overwidth loads (8'6" to typically 14–16 feet wide): Standard overwidth permit, may require escort vehicles depending on width.
Overheight loads (above 13'6"–14' depending on state): Requires route surveys to identify clearance obstacles (bridges, underpasses, overhead utilities).
Overweight loads (over 80,000 lbs gross, or axle weight limits): Requires a superload or overweight permit, often requires specific axle configurations to spread weight.
Superloads (over 250,000 lbs or very large dimensions): Require complex engineering, multi-state route surveys, utility coordination, and law enforcement escort in many cases.
Permit procurement is a service unto itself. Some flatbed brokers handle permits internally; others work with permit services that handle the state-by-state applications. For routine OD freight (a load that's 10 feet wide but not otherwise unusual), permit turnaround is typically 24–48 hours. For complex superloads, permit procurement can take weeks.
Securement Requirements
The Federal Motor Carrier Safety Administration (FMCSA) has specific cargo securement rules that govern flatbed loads. Cargo that falls or shifts in transit can cause catastrophic accidents, and securement requirements are taken seriously.
General securement requirements cover the type and number of tie-downs based on cargo weight and length, blocking and bracing requirements for specific cargo types, and driver responsibility to inspect securement at pickup and after the first 50 miles of transit.
Brokers need to understand enough about securement to:
- Recognize when a shipper's loading instructions are problematic
- Know whether a carrier loading a heavy coil the wrong way is creating a liability
- Communicate accurately with carriers about what securement equipment is needed
This knowledge comes from experience — visiting shipper facilities, asking questions, and learning from carrier feedback.
The Flatbed Carrier Pool
Flatbed carriers are a distinct community from dry van carriers. Key differences:
Equipment investment: Flatbed trailers require tie-downs, straps, chains, tarps, and other securement equipment that dry van trailers don't. Operators who take care of their equipment — fresh straps, properly maintained tarps — are a signal of professionalism.
Driver skill: Flatbed loading and securement requires more driver skill and engagement than closing van doors. Good flatbed drivers are more valuable and harder to replace.
Relationships over boards: Established flatbed brokers generally have deeper direct carrier relationships and are less dependent on load boards than dry van brokers. The carrier community for complex open-deck freight is smaller and more relationship-driven.
Scale: There are fewer flatbed carriers than dry van carriers, particularly at the specialized and over-dimensional end of the spectrum.
Margins in Flatbed
Flatbed freight consistently commands better margins than standard dry van for several reasons:
- Fewer carriers creates less pure price competition
- Complexity creates genuine expertise premium
- Permit coordination and special requirements add service value
- Shipper relationships in heavy industrial sectors tend to be longer and more loyal
Typical flatbed brokerage margins run 15–25% versus the 12–15% that's increasingly typical for commodity dry van in a competitive market.
Breaking Into Flatbed as a Broker
The most direct path to building a flatbed book is through industry knowledge:
Work with industrial shippers in your existing network. If you have connections to construction companies, manufacturing operations, or oil field services from prior career experience, you have an entry point.
Start with simpler flatbed before moving to over-dimensional. Standard flatbed loads (lumber, pipe, steel plate within legal dimensions) are a good introduction before tackling permit loads and heavy haul.
Build carrier relationships directly. Join trucking associations where flatbed operators are members, attend freight industry events, and build direct relationships with operators before you have loads for them. Flatbed carrier relationships are more durable and valuable than dry van relationships because the pool is smaller.
Learn the compliance side. Take time to understand FMCSA securement rules, state permit processes, and the logistics of OD freight. Carriers and shippers respect brokers who know what they're talking about.
Frequently Asked Questions
Is flatbed harder to learn than dry van?
Yes, the knowledge required is deeper — equipment types, securement regulations, permit processes, commodity-specific loading requirements. But the learning is finite and the expertise is defensible. Most brokers who specialize in flatbed say the complexity is what they enjoy about it.
Do I need to be able to procure permits myself?
Not necessarily. Several permit services (Overdrive Permits, National Permits, etc.) specialize in OD permit procurement and can handle the process on your behalf. As you grow, you may want to bring this capability in-house for cost and speed reasons.
What's hotshot brokerage and how is it different?
Hotshot loads are smaller, often urgent loads moved by pickup-truck-and-gooseneck combinations. They typically serve oil field, construction, and agricultural customers who need rapid delivery of machinery parts, equipment, and supplies to job sites. Hotshot rates are typically higher per-mile than standard flatbed because of the urgency and smaller equipment investment, and the broker community for hotshot is separate from standard heavy haul.
Can I broker flatbed loads as a new broker?
Yes, though starting with standard flatbed within legal dimensions is lower risk than jumping directly into OD permit loads. Building relationships with flatbed carriers on standard loads first lets you learn the operational nuances before adding the permit complexity.
Do I need different software or TMS tools for flatbed vs. dry van?
Your core TMS will work for flatbed loads. For permit loads, you'll need either permit service integrations or a permit management workflow. Some specialized TMS platforms have permit tracking built in; others require manual management or integration with permit services.
