Flatbed Shipping for Data Center Construction: A 2026 Guide for Contractors and Suppliers
Data centers are now the biggest driver of new construction freight in the country. Flatbed shipping for data center construction covers everything from structural steel and rebar to cable reels, cooling units and switchgear, and the build-out is keeping open-deck trucks in short supply. FreightWaves analysts noted in September 2026 that flatbed rates remain elevated, supported in part by data center construction.
This guide covers what data center freight looks like, which loads fit a standard flatbed and which need specialized trailers, how job site deliveries work, and how to lock in capacity. It is written by MigWay, an asset-based carrier in Pineville, North Carolina, running 400 trucks and 750 trailers across dry van and flatbed, just south of one of the busiest data center corridors in the Southeast.
How big is the data center construction boom in 2026?
Data center construction is at record levels in 2026. U.S. Census Bureau data showed spending at a $50.7 billion annual rate in April 2026, up 27% from a year earlier. That made data centers larger than all other private office construction combined, according to Data Center Knowledge.
- Record starts: ConstructConnect reported $22.3 billion in data center construction starts in June 2026, the second-highest month on record.
- Year-to-date: starts reached $81.5 billion through June, already above all of 2025's $72.5 billion.
- Rising costs: median construction cost hit $570 per square foot in 2026, up 38% from $415 in 2025.
- Deep pipeline: ConstructConnect tracks 85 projects in preconstruction worth $78.2 billion through year-end.
Every one of those projects needs thousands of truckloads of steel, concrete, electrical and mechanical equipment. Much of it moves on flatbeds and step decks.
Where are data centers being built near the Carolinas and Mid-Atlantic?
North Carolina was one of four states with more than $10 billion in data center construction starts in the first half of 2026, per ConstructConnect. The Southeast and Mid-Atlantic are among the busiest regions in the country.
| Region | Activity | Main freight corridors |
|---|---|---|
| Charlotte metro and Catawba County, NC | PowerHouse Data Centers' Charlotte campus and Microsoft's Catawba County campus under construction; Apple's Maiden campus operational | I-85, I-77, I-40, US-321 |
| Richmond County, NC | Amazon Web Services campus under construction, about $10 billion | US-74, US-220, I-73/74 |
| Northern Virginia and Richmond, VA | The largest data center market in the U.S., still expanding | I-95, I-66, I-81 |
| Central Ohio | Large hyperscale campuses around New Albany and Columbus | I-70, I-71, I-270 |
| Georgia and South Carolina | Growing campuses around Atlanta and in the Lowcountry | I-85, I-20, I-26 |

What materials ship on flatbeds for data center construction?
Most data center construction freight fits one of three phases: the structure, the electrical and mechanical systems, and the fit-out. Here is what typically moves on a standard 48 or 53-foot flatbed.
| Material | Project phase | Typical equipment | Handling notes |
|---|---|---|---|
| Structural steel beams, columns and joists | Structure | 48 or 53-ft flatbed, often spread axle | Chains or straps, dunnage between tiers |
| Metal roof and floor deck | Structure | Flatbed | Tarp to prevent rust and staining |
| Rebar and wire mesh | Foundation | Flatbed | Bundled and tagged for sequencing |
| Precast concrete panels and pipe | Structure and site work | Flatbed or step deck | Heavy point loads; wide panels may need permits |
| Conduit, cable tray and pipe | Electrical and mechanical | 53-ft flatbed for long lengths | Bundled, blocked and strapped |
| Medium-voltage cable reels | Electrical | Flatbed or step deck | Chocked and chained; heavy for their size |
| HVAC units, air handlers and smaller chillers | Mechanical | Flatbed or step deck, depending on height | Tarped; lifting points protected |
| Crated electrical gear and battery cabinets | Electrical | Flatbed with tarps, or dry van if dock-loadable | Moisture and shock sensitive |
For more detail on specific materials, see our guides to structural steel flatbed shipping, precast concrete and pipe transport and HVAC and industrial equipment shipping.
Which data center loads need specialized trailers?
The largest data center equipment is often too heavy, tall or wide for a standard flatbed. These loads usually move on step decks, RGNs or multi-axle heavy-haul trailers under state permits.
- Backup generators: multi-megawatt diesel gensets in enclosures can exceed standard flatbed weight and height limits.
- Substation transformers: large power transformers often need heavy-haul trailers, permits and route surveys.
- Large chillers and cooling towers: often too tall for a flatbed's roughly 8 feet 6 inches of legal freight height.
- Prefabricated power modules: e-houses and power skids are often over-width.
- Battery storage containers: usually step deck, sometimes over-weight.
The rule of thumb: anything over about 8 feet 6 inches tall, 8 feet 6 inches wide, or 46,000 to 48,000 pounds will not move as a standard flatbed load. Our flatbed trailer dimensions guide explains the limits and permit process.
How do flatbed deliveries to data center job sites work?
Data center job sites are larger and more controlled than most construction sites. A delivery that works at a lumber yard can fail at a hyperscale campus.
What to plan for
- Delivery windows: sites often book deliveries to the hour so cranes and crews are ready. A truck that arrives early may wait; one that arrives late may be turned away.
- Security and badging: gates may require driver ID, pre-registration or a site orientation.
- PPE: hard hat, high-visibility vest, safety glasses and steel-toe boots are standard.
- Site conditions: unpaved or muddy access roads during early phases can limit where a loaded flatbed can go.
- Crane or forklift offloading: confirm who unloads and with what equipment before the truck arrives.
- Laydown yards: some projects stage material at a nearby yard and shuttle it in.
- Sequencing: steel and electrical gear often must arrive in a set order to match the erection schedule.
Share the site's delivery rules with your carrier at booking. It is the single best way to avoid failed deliveries and extra charges.
How can contractors secure flatbed capacity for data center projects?
Flatbed capacity is tight in 2026. IEL reported flatbed tender rejections near 20% in late September, meaning carriers turned down about 1 in 5 contracted flatbed loads. Data center projects compete with highway work, manufacturing and general construction for the same trucks.
- Share the schedule early. Give carriers the project timeline and expected load counts by phase, even if they are rough.
- Commit core volume. A dedicated or contracted flatbed plan for steel and recurring materials keeps you off the spot market.
- Use asset carriers on critical loads. A carrier with its own trucks and drivers can commit capacity a broker cannot always guarantee.
- Match equipment to freight. Book step decks and heavy haul separately and early. They are scarcer than flatbeds.
- Plan for weather. Tarped loads take longer to secure, and winter cuts working hours in the Ohio Valley and Mid-Atlantic.

Flatbed shipping for data center construction is growing with record project spending, and capacity is tight. Most structural, electrical and mechanical materials move on standard flatbeds, while generators, transformers and large chillers need specialized equipment. Share schedules early, commit core volume to asset carriers, and plan every delivery around the site's rules.
Frequently Asked Questions
What freight is used in data center construction?
Common data center construction freight includes structural steel, metal deck, rebar, precast concrete, conduit, cable reels, HVAC units, electrical gear, generators and transformers. Most structural and electrical materials move on flatbeds and step decks.
How much is being spent on data center construction?
Census data showed data center construction spending at a $50.7 billion annual rate in April 2026, up 27% from a year earlier. ConstructConnect reported $81.5 billion in data center construction starts through June 2026.
Why are flatbed rates high in 2026?
Demand from data center, highway and manufacturing projects is strong while truck and driver capacity is shrinking. Flatbed tender rejections were near 20% in late September 2026, and analysts cite data center construction as one support for high rates.
Can data center generators ship on a standard flatbed?
Usually not. Large backup generators in enclosures often exceed standard flatbed weight or height limits. They typically move on step decks, RGNs or heavy-haul trailers with permits.
What trailer is best for switchgear?
Crated switchgear that can be dock-loaded often ships in a dry van. Larger lineups move on flatbeds or step decks with tarps. Switchgear is sensitive to moisture and shock, so protection matters.
Where are data centers being built in North Carolina?
Active projects include Amazon Web Services in Richmond County, PowerHouse Data Centers in Charlotte and Microsoft in Catawba County. Apple operates a campus in Maiden. Plans change, so confirm status before planning around a project.
What do drivers need to deliver to a data center site?
Drivers usually need PPE, including a hard hat, safety vest, glasses and steel-toe boots. Many sites also require pre-registration, ID checks and a scheduled delivery window.
How far in advance should I book flatbeds for a construction project?
Share the project schedule as early as possible and book recurring loads under a contract. For single loads, 24 to 48 hours is typical, but step decks and heavy haul need more lead time.
How much can a flatbed carry for construction materials?
A standard five-axle flatbed can legally carry about 46,000 to 48,000 pounds. Freight up to about 8 feet 6 inches tall and 8 feet 6 inches wide moves without permits in most eastern states.
