Shipping Lumber, Steel, and Coils on Open Deck

Building materials don’t ride in a box truck. Lumber comes in long bundles that hang past the deck. Steel is heavy, dense, and unforgiving. Coils want to roll, and a coil that gets loose is a serious problem. If you ship any of these, you already know that a lot of carriers either bounce the load or hit you with charges that weren’t in the quote. The freight itself is fine. The handling is the hard part.

Here’s how we think about moving each one, and what to watch for before the truck shows up.

Lumber and dimensional loads

Lumber is bulky and often long. A bundle of studs, trusses, or treated timbers can run well past the length of a standard deck, and once you cross into overlength territory you’re into flagging, and sometimes permits, depending on the route.

A few things make or break a lumber move:

• Tarping. Treated and finished lumber usually needs to stay dry. Tarping adds time and cost, and it needs to be done right so wind doesn’t tear it apart at highway speed. Say up front whether your load tarps.
• Weight distribution. Long bundles have to be spread across the deck so no single point carries too much and axle weights stay legal.
• Securement. Enough straps or chains for the length and weight, with edge protection so the straps don’t bite into the wood.

None of this is exotic, but it is easy to get wrong if the crew doesn’t handle lumber regularly.

Steel: plate, bar, beams, and pipe

Steel is where density catches people off guard. A load can look small and still max out the trailer’s legal weight. Beams and pipe bring length into the picture too, so you’re often dealing with heavy and long at the same time.

The securement rules for metal are strict for a reason. Steel doesn’t compress, it doesn’t grip the deck the way softer freight does, and if it shifts it shifts hard. That means chains and binders rated for the load, dunnage to keep it stable, and blocking so nothing slides forward under braking. This is standard open-deck work, but it demands a driver who knows metal and doesn’t cut corners on tie-downs.

If your steel is oversized, over-length, or over-weight, you’re into the permitted world: route planning, state permits, and sometimes escorts. That’s stressful the first time you do it. It’s routine when the team handling it does it every week.

Coils: the one you can’t improvise

Coils are their own category. A steel coil is heavy, round, and wants to roll, which makes it one of the least forgiving things you can put on a deck. Securement depends on how the coil sits:

• Eye to the sky loads differently than eye to the side or suspended.
• Coil racks or timber cradles keep the coil from rolling.
• Chains have to be rated and positioned for the orientation, not just thrown over the top.

There is no room to wing this. A coil that isn’t cradled and chained correctly is a hazard to the driver and everyone else on the road. If you’re shipping coils, ask how the carrier plans to secure them before you book. A straight answer tells you they’ve done it.

Why building materials get bounced by LTL

If you’ve tried to move a few bundles of steel or lumber through a big LTL network, you’ve probably seen the load rejected or hit with linear-foot and density charges. That’s not carriers being difficult. Long, heavy, low-density freight is exactly what their pricing is built to discourage, and hard-to-handle open-deck material doesn’t fit their docks.

That’s why open deck exists. And if you don’t have a full trailer’s worth, you don’t have to pay for one. Partial flatbed lets you put one to several pieces on shared deck space. When your building-materials move is small, our sister brand FlatbedLTL (flatbed.delcoe.com) is built for exactly that, with pricing that doesn’t surprise you at the end.

What we need to quote it right

The fastest way to a clean quote and a smooth pickup is to tell us the real dimensions and weight up front. For any open-deck building-materials load, have this ready:

1. Commodity and form (lumber bundles, plate, beams, coils, pipe).
2. Dimensions, especially length, and total weight.
3. Whether it tarps.
4. For coils, the orientation they’ll ship in.
5. Pickup and delivery points, and any dock or crane limits.

With that, we can tell you the right equipment, whether you’re looking at permits, and what it actually costs. No guesswork, no reclass surprise on the invoice.

Comet National has been moving open-deck freight since 1995, to all 48 states and Canada, and building materials are squarely in our wheelhouse. If you’ve got lumber, steel, or coils to move, call us or ask for a quote, and tell us what you’re shipping. We’ll tell you the straight story on how to get it there safely.
