When shipping freight that won't fit in an enclosed trailer—whether due to size, shape, or weight—you'll typically be looking at flatbed equipment. But should you use a standard flatbed or a step deck? Let's break down the differences.
Standard Flatbed Trailers
A standard flatbed is exactly what it sounds like: a flat trailer bed with no sides or roof.
Specifications:
Deck height: ~60" from ground
Standard length: 48' or 53'
Legal max width: 8'6"
Legal max height: 8'6" (for total 13'6" from ground)
Weight capacity: ~48,000 lbsBest for:
Building materials
Machinery
Steel, lumber, pipe
Any freight under 8'6" tallStep Deck (Drop Deck) Trailers
A step deck has two levels: a shorter upper deck near the cab and a lower main deck.
Specifications:
Upper deck height: ~60"
Lower deck height: ~38-42"
Lower deck length: 37-40'
Legal max height: 10' on lower deck
Weight capacity: ~48,000 lbsBest for:
Taller machinery
Construction equipment
Agricultural equipment
Freight 8'6" to 10' tallDouble Drop (Lowboy) Trailers
For the tallest or heaviest freight, double drops offer even more clearance.
Specifications:
Well height: 18-24"
Legal max height: ~11'6" in well
Typically shorter decks
Weight capacity: varies (some rated for heavy haul)Best for:
Heavy equipment
Tall industrial machinery
Items over 10' tallHow to Choose the Right Equipment
Consider Height First
Measure your freight including any packaging or securing materials. Add a few inches for clearance and securing.
| Freight Height | Recommended Equipment |
|---------------|---------------------|
| Under 8'6" | Standard Flatbed |
| 8'6" - 10' | Step Deck |
| Over 10' | Double Drop or Permits |
Consider Weight
All standard flatbeds have similar weight limits (~48,000 lbs). For heavier loads, you'll need specialized heavy haul equipment.
Consider Loading
Flatbeds can be loaded from sides or rear
Step decks require ramps for the upper deck
Consider your loading/unloading capabilitiesTarping and Securing
Open deck freight requires proper securement:
Chains, straps, or binders rated for cargo weight
Tarping may be required (lumber tarps, smoke tarps, etc.)
