Flatbed trailers aren't one-size-fits-all—the type you choose directly impacts load security, cost, and delivery success. Whether you're shipping machinery, steel coils, or oversized equipment, understanding the differences between flatbed variants will help you avoid expensive mistakes and delays. Getting it right means faster quotes, better rates, and trailers that actually fit your cargo.
Standard Flatbed Trailers
The workhorse of freight transport, a standard flatbed is typically 48–53 feet long with a 8.5-foot width and 102-inch deck height. These handle most general cargo: lumber, machinery, equipment, and palletized goods up to around 45,000 pounds.
Standard flatbeds cost between $3,500–$6,500 per load for regional hauls (250–500 miles) and $5,000–$9,000+ for cross-country moves, depending on freight class and market conditions. No tarping or special equipment is included—you're paying for the deck space alone.
Curtainside & Tarp-Covered Flatbeds
If your load needs weather protection but isn't suited for an enclosed trailer, a curtainside flatbed adds retractable fabric walls. These are ideal for palletized goods, textiles, or anything vulnerable to rain or dust without being fragile enough to require a box trailer.
Tarp coverage protects from the elements while keeping costs lower than full enclosure—expect to pay $500–$1,200 extra per load for tarp service. Curtainside trailers run $4,500–$7,500 for comparable distances.
Extendable & Stretch Flatbeds
Long loads—pipe, beams, or oversized machinery—often need an extendable flatbed. These trailers extend 5–10 feet beyond the standard 53-foot deck, accommodating loads up to 70+ feet while staying legal under most state regulations.
Because they require specialized handling and often escort vehicles, extendable flatbeds command premium pricing: $6,000–$10,000 for regional moves, sometimes higher for loads exceeding 70 feet. Always confirm state-specific overhang laws before booking; regulations vary significantly.
Drop Deck & Step Deck Trailers
A drop deck (or step deck) lowers the rear deck 2–3 feet, creating extra headroom for tall cargo that exceeds standard 102-inch height restrictions. These work well for machinery with height over 7 feet, compressors, or equipment with protruding components.
Pricing typically runs 10–20% higher than standard flatbeds: $4,000–$7,500 regionally. The extra clearance is worth it if your cargo hits height limits on standard trailers—salvage costs from deck damage dwarf the upgrade fee.
Specialized Flatbeds for Heavy Haul
Loads exceeding 80,000 pounds (gross) or extremely odd dimensions need heavy-haul flatbeds. These low-decks, hydraulic trailers, and specialized rigs accommodate weights up to 250,000+ pounds and require pilot cars, route planning, and permitting.
Heavy-haul moves are priced per-pound or flat-rate depending on distance and complexity—expect $1.50–$3.00+ per pound for loads over 100,000 pounds. A 150,000-pound turbine might cost $15,000–$30,000 for a 500-mile move. Budget 2–4 weeks for permitting.
Key Considerations When Choosing
Match deck type to cargo weight and sensitivity:
- Under 30,000 lbs, fragile items → consider enclosed
- 30,000–45,000 lbs, weather-sensitive → curtainside
- 45,000+ lbs or odd dimensions → extendable or drop deck
- Over 80,000 lbs or super-specialized → heavy-haul partner
Verify dimensional limits. Width, height, and overhang restrictions vary by state and route. Confirm before booking—moving a load that violates height restrictions can cost thousands in fines and delays.
Account for load-securing costs. Chains, straps, and labor run $200–$800 per load depending on complexity. Some carriers include this; others charge separately.
Plan for seasonal pricing swings. Flatbed rates increase 15–25% during peak agricultural and construction seasons (spring/fall). Winter typically offers slightly lower rates but weather delays are common.

Frequently Asked Questions
Q: What's the difference between a flatbed and a drop deck, and when should I use each? A standard flatbed has a uniform 102-inch deck height and works for most cargo under 7 feet tall; a drop deck lowers to 84–86 inches at the rear, giving extra clearance for taller equipment without exceeding height restrictions.
Q: How much does it cost to ship a load that exceeds the standard 53-foot length? Extendable flatbeds typically cost 15–30% more than standard flatbeds; a 65-foot load might run $6,500–$8,500 regionally versus $5,000–$6,500 for a standard 53-foot move, plus any special routing fees.
Q: Do I need permits for oversized loads, and how long do they take? Yes—loads exceeding state width (typically 8'6"), height (13'6"), or length (53' without special equipment) require permits; timelines range from 24 hours for simple moves to 2–4 weeks for multi-state heavy-haul shipments.
