Over-Dimensional

Over-Dimensional (OD)

Freight that measures past legal limits still ships on schedule when the plan respects the measurements. Freight Flex coordinates over-dimensional freight on specialized trailers with over-dimensional permits and route planning handled, moving the loads that are too wide, too tall or too long for standard equipment.

Legal limits end; your freight keeps moving.

Over-dimensional freight exceeds standard legal dimensions, typically running wider than 8.5 feet, taller than clearance allows or longer than a standard deck, while often staying within legal weight. Freight Flex coordinates OD shipping with specialized equipment, over-dimensional permits and route planning, so freight that outgrows a standard trailer keeps a standard level of predictability.

Built for freight that measures over

Machinery a few inches too wide, tanks a foot too tall, structural steel that runs long. OD freight is everywhere in manufacturing and construction, and most of it moves on familiar equipment with the right permits attached. If your freight breaks a dimension limit but not the scales, OD is usually the mode, and it prices well below full heavy haul.

Step decks, double drops and stretch trailers

The trailer choice is how OD freight gets back under the limits. A step deck buys roughly two feet of height clearance over a standard flatbed, a double drop buys more for the tallest freight, and stretch configurations carry length that would overhang a standard deck. Freight Flex matches the configuration to your exact measurements, drawn from a deep network of open deck carriers.

Over-dimensional permits and routing handled

OD loads require state over-dimensional permits, and each state issues them against specific dimensions, routes and dates. Freight Flex handles the permits and the route planning together, checking clearances and restrictions along the path, so the load moves on a route it is actually permitted to travel.

The right specialized trailer for the measurements

Step decks, double drops, stretch trailers and multi-axle setups each solve a specific dimension problem. Freight Flex matches the configuration to your exact freight, so you never pay heavy haul rates for a load a step deck handles cleanly.

Permits and routes planned as one

An OD permit is only valid on its stated route. Freight Flex secures over-dimensional permits and plans the routing together, verifying clearances and restrictions along the way, so the permit in the cab matches the road under the truck.

OD capacity from vetted open deck carriers

Over-dimensional freight rides with carriers experienced in wide and tall loads, drawn from the same vetted network that powers our flatbed service. Carrier compliance tools and an agent success team available 24/7 support the move, because unusual freight deserves consistent discipline.

The Freight Flex promise

Measured right, permitted right, moved right.

We commit to matching your over-dimensional freight with the specialized trailer its measurements require, securing the over-dimensional permits for every state on the route, and planning the path around clearances and travel restrictions before dispatch. The carrier is vetted, the schedule respects permitted travel windows, and if the load's specs push it into full heavy haul territory, we tell you before we quote it, not after.

Who we serve

OD programs for freight that runs wide.

Over-dimensional freight is daily reality for the industries that make and build at scale. Freight Flex moves OD loads for manufacturers shipping machinery and fabricated assemblies, building materials producers with trusses, tanks and structural components, energy companies moving equipment to project sites, and agriculture operations relocating implements. Your team learns which of your products run over and plans them as routine.

Planning OD freight

Inches decide everything.

In over-dimensional shipping, the difference between a routine permitted load and an expensive escorted one can be a single foot. Exact measurements taken early are the highest-value work in the whole move.

Measure the freight the way the state will

Measure loaded dimensions, not catalog dimensions. Width includes anything that protrudes, height is measured from the ground with the freight sitting on the actual trailer deck, and length includes overhang. A machine listed at 8.5 feet wide that measures 8 feet 10 inches with its fittings is an OD load, and discovering that at pickup means a rejected dispatch and a rebooked truck. Permit thresholds also step up as dimensions grow, so a load a few inches narrower can sometimes travel with lighter requirements, which is worth knowing before the freight is crated. Send Freight Flex exact numbers and photos when possible, and the quote comes back with the right trailer, the right permits and no surprises at the scale house.

OD, heavy haul or flatbed, get the category right

The three open deck categories are neighbors, and the boundaries are worth knowing. Freight within all legal limits ships as standard flatbed at the best rates. Freight over on dimensions but manageable on weight ships as OD with permits and specialized trailers. Freight that is massively overweight, needs escorts and surveys or pushes multi-axle territory belongs in heavy haul, and multi-piece programs moving on a project schedule roll up into project cargo coordination. Freight Flex quotes across all four, so a load is classified by its actual measurements and the price follows the freight rather than the label. When your load sits near a boundary, we price both sides and show you the difference.
