Flatbed Trailer Dimensions & Shipping Guide
The Backbone of Open-Deck Freight
Flatbed Trailer Dimensions: Quick Specs
Flatbed trailers offer unmatched versatility for open-deck shipping, providing the strength and accessibility needed for heavy or oversized freight. From CNC machines and industrial equipment to steel beams and building materials, flatbeds handle cargo that can’t fit in enclosed trailers or requires top, side, or crane loading.
Their durable, open design and high capacity make them the preferred solution for safe, efficient transport across the United States, Canada, and Mexico.

What Flatbeds Haul Best
Flatbeds excel in hauling freight that requires flexibility, side-loading access, or special securement considerations. Common shipments include:
- CNC Machines & Industrial Equipment
- Steel Beams, Pipes & Coils
- Lumber, Building Materials & Prefab Panels
- Heavy Machinery & Attachments
- Generators, Tanks & Industrial Tools
- Crated or Palletized Freight
Ideal Industries: Manufacturing, Construction, Energy, Infrastructure, and Auction Resells
Navigating Height Regulations
A standard flatbed allows for 8’6″ of cargo height, but legal height limits vary by state. Western states often permit a total height of up to 14 feet, while many eastern states cap it at 13’6″. This means a load that is legal on a flatbed in California may require an overheight permit, or a different trailer such as a step deck, to travel to states like New York.

A Brief History of Flatbed Freight
Flatbed trailers originated in the early 1900s when horse-drawn wagons were replaced by motorized steel platforms. As the U.S. highway system expanded, flatbeds became essential for moving infrastructure materials like beams, rebar, and heavy machinery. Modern flatbeds have evolved significantly, now equipped with air-ride suspension, lightweight aluminum frames, and securement systems that meet FMCSA standards. The result is a safer, smoother, and more efficient way to move freight from pickup to final delivery.
Equipment & Load Securement
Proper securement ensures safety, compliance, and protection for your freight. Carriers must follow FMCSA 393.100 cargo securement regulations. Common Securement Tools for a flatbed:
Chains & Binders
for machinery, steel, and heavy freight
Straps & Edge Protectors
for finished goods and delicate cargo
Tarps
to shield against weather and road debris
Dunnage & Blocking
for balance and elevation
