Flatbed trailers are open-deck trailers designed for freight that requires flexible loading access or cannot easily fit inside an enclosed trailer. With no fixed roof or side walls, cargo can be loaded and unloaded from the rear, sides, or above using forklifts, cranes, or other handling equipment.
Flatbed trailers are open-deck trailers designed for freight that requires flexible loading access or cannot easily fit inside an enclosed trailer. With no fixed roof or side walls, cargo can be loaded and unloaded from the rear, sides, or above using forklifts, cranes, or other handling equipment.
They are commonly used for steel, lumber, machinery, construction materials, and other oversized or irregularly shaped freight that can be safely secured to an open deck.
Key characteristics:
Open, continuous deck
Side, rear, and top loading access
Suitable for oversized and irregularly shaped freight
Commonly available in 48 ft and 53 ft lengths
Cargo is secured using straps, chains, or other approved securement methods
Can accommodate over-dimensional freight when routing and permit requirements are met

Available Sizes & Configurations
Standard Flatbed trailers are commonly available in two main lengths:
48 ft Flatbed
53 ft Flatbed
Both sizes use the same basic open-deck design. Equipment may also vary by axle configuration depending on the trailer, cargo weight, and route requirements.
For loads that exceed the practical length of a standard Flatbed, an Extendable / Stretch Flatbed may be required and is treated as a separate trailer type in this guide.

About 46,000–48,000 lbs
Note: Dimensions, deck height, and payload capacity may vary by trailer configuration, manufacturer, tractor setup, cargo distribution, and applicable weight regulations. Oversized or over-dimensional freight may require permits, route planning, escorts, or specialized equipment.
Best For / Not Ideal For
✅ Best For
❌ Not Ideal For
Steel and structural materials
Weather-sensitive cargo without adequate protection
Lumber and building materials
Temperature-controlled freight
Machinery and industrial equipment
Freight requiring a fully enclosed trailer
Construction materials
Very tall cargo better suited to a Step Deck or Lowboy
Oversized or irregularly shaped freight
Self-propelled heavy equipment better suited to an RGN
Cargo requiring side or top loading
Small standard freight better suited to a Dry Van
Flatbeds are particularly useful when cargo dimensions or loading requirements make an enclosed trailer impractical. However, because the deck is open, weather exposure and cargo securement must be considered during shipment planning.

Loading & Handling Considerations
Before booking a Flatbed, confirm:
Total cargo weight
Cargo length, width, and height
Loading and unloading method
Required side, rear, or top access
Cargo securement requirements
Tarping or weather-protection needs
Weight distribution across the deck and axles
Over-dimensional permit requirements
Route restrictions or escort requirements, when applicable
When evauating flatbed options, always consider:
Flatbed freight must be properly secured for transit. Depending on the cargo, this may involve chains, straps, blocking, bracing, or tarps.
Because there are no fixed walls or roof, it is especially important to confirm the loaded dimensions and securement plan before booking.
When Should You Choose a Flatbed Trailer?
A Flatbed is usually a good option when your shipment:
Requires side, rear, or top loading access
Is too wide or irregularly shaped for a Dry Van
Does not require temperature control
Can be safely secured on an open deck
Includes steel, lumber, machinery, or construction materials
Fits within the practical height limits of a standard Flatbed
May require open-deck flexibility for oversized freight
A different trailer may be more appropriate when cargo requires additional vertical clearance, extra deck length, ground-level loading, or enclosed weather protection.
FAQs
What is a Flatbed trailer?
A Flatbed is an open-deck trailer without fixed side walls or a roof. Its open design allows freight to be loaded from the rear, sides, or above, making it useful for oversized, irregularly shaped, and industrial cargo.
What are the typical Flatbed trailer sizes?
Standard Flatbed trailers commonly used in North America are 48 ft or 53 ft long and approximately 102 in wide.
What type of cargo can move on a Flatbed?
Flatbeds are commonly used for steel, lumber, machinery, construction materials, industrial components, and other freight that benefits from open-deck loading access.
How much weight can a Flatbed carry?
LAC lists a typical load weight of approximately 46,000–48,000 lbs for its Standard Flatbed equipment. Actual capacity depends on the specific trailer, tractor setup, axle configuration, cargo distribution, and applicable regulations.
Can oversized cargo move on a Flatbed?
Yes. Flatbeds are frequently used for oversized or irregularly shaped freight. Cargo exceeding standard legal dimensions may require permits, approved routing, escorts, or other operational arrangements.
Does Flatbed cargo need to be covered?
Not always. Whether cargo requires tarping or another protective solution depends on the commodity and its sensitivity to weather. Freight that requires complete enclosure or temperature control may be better suited to another trailer type.
What is the difference between a Flatbed and a Step Deck?
A standard Flatbed has one continuous deck at a higher deck level. A Step Deck has an upper deck and a lower main deck, providing additional vertical clearance for taller cargo.
LAC coordinates Flatbed and other Ground Freight solutions across North America based on your cargo, dimensions, route, timing, and equipment requirements.
