Heavy, sharp and worth a lot.

Steel freight is heavy for its size, so a truckload almost always runs out of weight before it runs out of deck. The products that move most often by truck are coils (hot-rolled, cold-rolled, galvanized and stainless), plate, sheet in lifts, rebar in bundles, pipe and tube, and structural shapes such as wide-flange beams, channel and angle. Most loads start at a mill or a steel service center and end at a fabricator, a stamping plant, a pipe yard or a construction site.

A typical run is a load of coils from a mill near Gary, Indiana to a stamping plant outside Detroit, or line pipe leaving a Houston yard for a Dallas distributor on the Houston to Dallas flatbed lane. On that lane the drive is about 240 miles, so one driver can load in the morning and deliver the same day. What the two loads share is concentrated weight, sharp edges, high value per pound and very little tolerance for a missing chain or a wet tarp.

The trailer follows the product's shape, its weight and how the receiver unloads it. Most steel rides on a flatbed because overhead cranes and forklifts load it from the top or the side. A step deck earns its place when the load is tall, because its lower deck sits about 3 ft 6 in off the road (typical) and leaves room for freight about 10 ft tall. Long members go on a stretch flatbed, and the trailer guide lists typical deck lengths for each.

The unloading end decides as much as the product does. A fabricator with an overhead crane can pull a coil straight off a flatbed, but a job site with only a rough-terrain forklift needs the load built so every bundle can be reached from the side. Tell the carrier which it is before the trailer is chosen.

The federal coil rule, 49 CFR 393.120 (opens in a new tab), covers metal coils weighing 5,000 lb or more, alone or grouped together, and the method changes with the direction of the eye (the hole through the middle). The mill decides the orientation when it loads, so the carrier needs to know it before dispatch, not at the dock.

With the eye vertical, the coil stands on its flat end like a roll of tape on a desk. A single coil needs two diagonal tiedowns crossing the eye, one transverse tiedown over the eye, and blocking or friction mats against forward movement. With the eye crosswise, the coil can roll forward or back, so the rule requires an anti-roll device (timbers, chocks, wedges or a cradle). Nailed blocking or a nailed wood cradle alone is prohibited, and so are tiedowns crossing in an X pattern. With the eye lengthwise, the coil wants to roll sideways, and the rule sets a separate method for that position.

The coil rule only works if the truck arrives with the right gear, and that gear belongs to the carrier, not the mill. A coil rack is a steel cradle or set of bunks that holds a coil in a V. A coil well is a recessed slot in the deck that does the same job. Hardwood timbers and chocks wedge against the coil, and rubber friction mats under a vertical coil keep it from sliding.

Placement matters as much as restraint. A single heavy coil concentrates its whole weight on a few feet of deck, and many flatbeds carry a rating for how much concentrated weight they can take in one spot. A driver who has hauled coils knows to set the coil over the trailer's main beams and close enough to the tandem axles to keep each axle group legal. A driver who has not may show up with a flat deck, four straps and no coil gear. Ask for coil racks or a coil well by name on the order.

Plate, pipe, rebar and structural steel fall under the general securement rules, which set both a count and a strength. The count comes from 49 CFR 393.110 (opens in a new tab): an article longer than 10 ft, not blocked by a headerboard, needs two tiedowns for the first 10 ft plus one for every additional 10 ft or fraction. A bundle of 40 ft wide-flange beams therefore needs at least 2 + 3 = 5 tiedowns.

The strength comes from 49 CFR 393.106 (opens in a new tab): the working load limits of all tiedowns must add up to at least half the weight of the cargo. A 30,000 lb lift of beams needs at least 15,000 lb of combined working load limit, and five chains rated well above that meet both rules at once. Behind both sits the performance standard in 49 CFR 393.102 (opens in a new tab), which requires the system to hold 0.8 g of forward deceleration at breaking strength. Pipe stacked in tiers also needs chocks or stakes on the bottom row, and rebar bundles need dunnage between layers so a forklift can get its forks underneath.

Chain is the default on raw steel because steel edges cut synthetic webbing, sometimes in a single hard brake. Coils, plate, beams and rebar almost always ride on transport chain with ratchet or lever binders. Straps come out on finished, painted, galvanized or polished products, where chain links leave marks the customer will reject.

When straps go on steel, edge protection is not optional. Corner protectors or sleeves go at every point the strap crosses an edge, because an unprotected strap loses strength the moment it is nicked. Each tiedown counts toward the aggregate requirement only at its marked working load limit, so an unmarked strap or chain adds nothing on paper and may be written up at a roadside inspection.

Steel tests the weight rules harder than any other common flatbed freight. Under 23 CFR 658.17 (opens in a new tab), the federal limit on the Interstate is 80,000 lb gross, 34,000 lb on a tandem axle group and 20,000 lb on a single axle, and the bridge formula can lower the gross further depending on axle count and spacing. A typical flatbed takes up to about 48,000 lb of freight, but a load at that weight can still be illegal if it sits too far forward or too far back.

That is why the order needs the weight of each piece, not just the total. Three coils of 14,000 lb each can be spaced to balance the axles. One coil of 42,000 lb has to sit in exactly the right place. A single coil too heavy to ship legally is nondivisible, so states can permit it under the FHWA permit framework (opens in a new tab). A load of several coils is divisible, and states expect it split across trucks instead.

Tarps go on when the mill or the customer asks, and on many steel products they ask every time. Cold-rolled sheet, galvanized coil, coated and painted products, and stainless with a polished finish can stain, rust or spot from rain, road spray and winter salt. Hot-rolled coil, rebar and most structural steel usually ship bare because they rust on the surface anyway and get blasted or primed later.

Steel tarps are smaller and lower than the lumber tarps used on tall stacks, and coil tarps are cut to cover a single coil in a rack. Tarping takes time at the dock and adds a charge, so put the requirement on the order and make sure it appears on the rate confirmation before the truck rolls. A tarp must be secured as carefully as the load, since a flapping tarp chafes paint. For freight that cannot get wet at all, a Conestoga, with a rolling tarp system and an inside height of about 8 ft (typical), is the usual alternative to a tarped flat.

Steel moves on mill schedules, and those schedules set the pace for everything downstream. Many mills and service centers load by appointment, often on day shift, with one crane serving several bays, so a truck that misses its window can wait hours. Hours of service make that wait expensive: a driver gets 11 hours of driving inside a 14-hour window (opens in a new tab), so four hours at a mill leaves 14 minus 4 = 10 hours of window, and less than a full day's driving.

Construction season pulls rebar, structural and pipe toward job sites from spring through fall, and winter brings road salt that makes tarps more important on finished steel. Each spring, CVSA runs International Roadcheck, a 72-hour inspection blitz. The 2026 event ran May 12 to 14 with cargo securement as the vehicle focus (opens in a new tab), and in 2025, inspectors placed 18.1% of vehicles out of service (opens in a new tab) across 56,178 inspections.

Most steel claims trace back to information that did not reach the driver. The failures repeat often enough to list, with the step that prevents each.

• Wrong gear on arrival. A truck shows up without coil racks or enough chain. Prevent it by naming the gear and the eye orientation on the order.
• An overweight axle. The total is legal, but one coil sits over the drives. Prevent it with piece weights and a load plan before pickup.
• Cut straps. Webbing crosses a steel edge without a protector. Prevent it by specifying chain or protected straps.
• Rust or stain. Finished steel rides bare through rain. Prevent it by stating the tarp requirement in writing.
• Shifted pipe or beams. Too few tiedowns for the length. Prevent it with the 393.110 count worked out in advance.
• The wrong carrier. A load is re-brokered to a truck nobody vetted. Prevent it by confirming the truck at pickup matches the one booked.

Every item on that list is cheaper to fix on the phone the day before than at the mill gate.

A steel quote is only as accurate as the details behind it, because the gear, the trailer and the axle plan all depend on them. Send these with the request and the price you get back will hold.

1. Pickup and delivery city and state, with the facility type (mill, service center, plant, job site).
2. Pickup date and the appointment hours at both ends.
3. Product and form: coil, plate, sheet, rebar, pipe or structural shape.
4. Weight of each piece and the total weight.
5. Dimensions, especially length on beams, pipe and rebar.
6. Coil eye orientation (vertical, crosswise or lengthwise) and coil width and diameter.
7. Tarp requirement, and whether the finish allows chain.
8. How each end loads and unloads: overhead crane, forklift or side loading only.

If you are still deciding between a flatbed and a step deck, say so, and send the tallest piece's height. The quote form takes all of this, including commodity and weight, in one pass.

Our steel loads follow the same order every time: securement gets planned up front, weights get checked, and tarps go on when the mill or the customer asks. The planning happens before a carrier is offered the load, so the truck that arrives has the coil racks, the chain and the tarps the freight needs.

We book steel on flatbeds and step decks, from mill and service center pickups to heavy weight lanes, and we use dedicated lanes when the same freight moves every week. Every carrier is verified against FMCSA records, insured and approved by our compliance team before it sees a load. One person owns each load from booking to delivery, so the person who planned the chains is the one who answers when the mill moves your appointment. Your rate comes from that person, not a formula, and it reflects the gear, the tarps and the weight your load actually needs. If your steel also feeds a production line, the manufacturing page covers how we handle plant schedules.
