Flatbed and LTL (less-than-truckload) shipping serve fundamentally different purposes—and mixing them up costs money. Flatbed trucking handles oversized, irregularly shaped, or heavy cargo that requires open-deck transport, while LTL consolidates smaller shipments from multiple customers on a single truck. Understanding when each makes sense will help you avoid overpaying and delays.
What Is Flatbed Trucking?
Flatbed trucking moves cargo on an open trailer with no sides or roof. The load sits directly on the deck, secured with chains, straps, or edge protectors. This setup works for steel coils, construction equipment, machinery, lumber, and anything too large or oddly shaped for a standard enclosed trailer.
Flatbed rates typically range from $2.50 to $4.50 per mile for standard heavy hauls, though specialized loads (oversized permits, escort vehicles, pilot cars) push costs higher. A 500-mile flatbed shipment of industrial equipment might run $1,250 to $2,250 before fuel surcharges.
What Is LTL Shipping?
LTL consolidates partial loads from different shippers into one truck. You pay only for the space your freight occupies—measured in hundredweights (cwt). A 2,000-pound pallet might cost $800–$1,400 to ship regionally, depending on class rating and distance.
LTL works well for shipments under 10,000 pounds that fit standard pallets or crates and don't require special handling. The trade-off: slower delivery (4–7 days for regional routes) due to multiple stops and freight consolidation.
Key Differences at a Glance
| Factor | Flatbed | LTL | |--------|---------|-----| | Best for | Oversized, heavy, irreg. shaped cargo | Smaller, standard-sized shipments | | Payload capacity | 20,000–45,000 lbs | Up to 20,000 lbs (single shipment) | | Dimensions | No size restrictions | Typically fits pallet standard | | Speed | 2–4 days (direct routing) | 4–7 days (multiple stops) | | Cost model | Per-mile rate | Per-pound/cwt rate | | Equipment needs | Open deck, tarps, chains | Standard enclosed trailer |
When to Use Flatbed Trucking
Choose flatbed when:
- Your cargo exceeds standard trailer height (9'6") or width (8'6") without permits
- You're shipping steel, machinery, construction equipment, or vehicles
- Load weight requires dedicated capacity (typically 15,000+ lbs)
- You need direct, non-stop service
- Cargo requires specialized loading equipment like cranes or forklifts
For example, shipping a 30-ton press or a 40-foot steel beam across three states demands flatbed—not because of weight alone, but because standard trailers physically cannot accommodate the dimensions.
When to Use LTL Shipping
Choose LTL when:
- Your shipment weighs under 10,000 pounds
- Cargo fits on standard pallets or in standard crates
- You can tolerate 4–7 day delivery windows
- Budget is tight (you split truck costs with other shippers)
- Shipment destinations align with carrier consolidation hubs
A manufacturing plant shipping 15 pallets of parts to a distributor 800 miles away typically saves 40–50% using LTL instead of paying for a dedicated flatbed truck that's mostly empty.
Cost Comparison: A Real Scenario
Shipping a 12,000-pound metal fabrication 400 miles:
Flatbed option: $400 miles × $3.25/mile = $1,300 (plus fuel surcharge ~$130)
LTL option: 12,000 lbs ÷ 100 cwt = 120 cwt × $9–$12/cwt = $1,080–$1,440
In this case, LTL edges flatbed on price—but only if your part fits in the consolidation truck. Add a 12-foot height requirement, and flatbed becomes your only choice.
Red Flags and Considerations
Watch for hidden costs. Flatbed shipments requiring oversized permits, escort vehicles, or specialized equipment (crane, tarps, pilot cars) add $200–$800. LTL pricing varies wildly by freight class (Class 50 to Class 500), density, and handling requirements—always ask carriers for a detailed breakdown.
Mercoly makes it easier to compare flatbed and heavy-haul providers side-by-side, so you can see actual quotes from trusted carriers without calling ten companies.
Choosing the Right Partner
Request quotes from at least three carriers. Provide exact dimensions, weight, freight class (for LTL), special handling needs, and pickup/delivery locations. Ask about fuel surcharges, accessorial fees, and insurance coverage. For flatbed, confirm the carrier handles your specific cargo type—steel vs. machinery vs. vehicles—since some specialize.
Verify insurance, DOT safety ratings, and whether drivers are experienced with your cargo type. A cheap quote from an unvetted carrier can mean delays, damage, or worse.
Frequently Asked Questions
Q: Can I use LTL for cargo that's 10,000+ pounds but fits on a pallet? It depends on the carrier's weight limits and class rating—some LTL carriers handle freight up to 20,000 lbs. Always confirm with the carrier before booking; oversized LTL shipments may still cost as much as flatbed.
Q: Do I need insurance on top of the carrier's liability coverage? Carrier liability is typically limited ($0.50–$2.00 per pound); for high-value shipments, purchase separate cargo insurance to cover the full value.
Q: What's the difference between a "step deck" flatbed and a standard flatbed? A step deck (or drop-deck) has a lower rear section, allowing taller cargo to fit within standard height limits and potentially avoid oversized permits—ask your carrier if it's suitable for your load.
