How to Ship Steel, Metal & Raw Materials

Steel and metal freight is the backbone of American manufacturing and construction. From hot-rolled coils weighing 40,000 lbs to bundles of rebar, structural beams, and aluminum extrusions, metal products present unique shipping challenges centered on extreme weight, securement complexity, and precise loading requirements.

The flatbed trucking industry moves the majority of steel and metal freight, and experienced flatbed carriers understand the critical importance of weight distribution across axles, proper chain and binder placement, and coil cradle positioning. A poorly secured steel coil becomes a 20-ton projectile — this is not a commodity where you cut corners on carrier quality.

Whether you're a steel mill shipping to fabricators, a service center distributing cut-to-length orders, or a manufacturer receiving raw material, understanding metal freight logistics will help you avoid costly damage, detention charges, and safety incidents.

Equipment & Trailer Types Needed

Choosing the right trailer is the single most important decision in any shipment. Here's what works for this freight type and why.

Flatbed Trailer

Standard platform for steel beams, plate, pipe bundles, and structural shapes — allows crane loading from above and forklift loading from the sides

Coil Trailer (Coil Car)

Specialized flatbed with built-in coil wells (cradles) that secure round coils of steel, aluminum, or wire — standard flatbeds lack this critical feature

Step Deck Trailer

Lower deck height accommodates tall loads like stacked steel plate or tall bundles of structural steel that would exceed standard flatbed height limits

Heavy-Haul Multi-Axle

For individual steel components or assembled loads exceeding 48,000 lbs — common for large forgings, casting molds, and oversized fabrications

Packaging & Preparation Tips

✓Steel coils must be loaded with the eye (hole) facing sideways or vertically per FMCSA 49 CFR 393.120 — never with the eye facing fore-and-aft as this allows rolling
✓Use coil racks or wooden cradle blocks on standard flatbeds when a coil trailer isn't available — coils placed directly on a flat deck will roll
✓Apply VCI (Vapor Corrosion Inhibitor) paper or spray to exposed metal surfaces to prevent rust during transit — even overnight dew can cause surface oxidation
✓Band bundles of rebar, angle iron, and tubing tightly with steel straps at minimum 3 points — loose bundles shift dangerously and damage truck decks
✓Place dunnage (4x4 lumber) under steel plate stacks to allow forklift tines to access the bottom plate at delivery without damaging the trailer deck
✓Cover non-galvanized steel with tarps during transit to prevent water staining and surface rust — carriers typically charge $50-$100 for tarp service

Common Mistakes to Avoid

✗Overloading axles — steel is extremely dense and a full flatbed of plate can easily exceed 48,000 lbs; always calculate axle weights before loading to avoid DOT fines
✗Using insufficient securement — steel loads require Grade 70 transport chain with load binders; ratchet straps alone are inadequate for coils, beams, or plate stacks
✗Loading coils on standard flatbeds without cradles, relying only on chains — one broken chain at highway speed can release a 40,000-lb coil
✗Not communicating mill loading procedures to the driver — many steel mills have specific dock protocols, PPE requirements, and loading sequences that carriers must follow
✗Assuming all flatbed carriers handle steel — experienced steel haulers understand weight distribution, coil securement, and mill protocol; general flatbed carriers may not

Cost Factors & Pricing Considerations

$Weight-based pricing dominates steel freight — most lanes quote per hundredweight (CWT) or per ton rather than flat-rate, so heavier loads cost proportionally more

$Steel tariffs, trade policies, and commodity prices directly affect shipping volumes and carrier availability, causing significant rate volatility quarter to quarter

$Mill-to-fabricator lanes (e.g., Gary IN to Houston TX, Nucor to service centers) have consistent capacity and competitive rates; unusual lanes cost 15-30% more

$Detention charges at steel mills are common and costly ($75-$100/hour after 2 hours) — mills often have long wait times for crane loading, especially during shift changes

$Tarp requirements add $50-$150 per load and increase loading time — some steel products require tarps while galvanized or coated materials typically don't

Frequently Asked Questions

How much does a full truckload of steel weigh?

A full truckload of steel typically weighs 40,000-48,000 lbs depending on the product type and trailer weight. The maximum payload on a standard flatbed is approximately 48,000 lbs (80,000 lb gross vehicle weight limit minus ~32,000 lbs for the truck and trailer). Steel plate, coils, and billets easily reach maximum weight before filling the trailer's physical space.

What are the FMCSA securement requirements for steel coils?

FMCSA 49 CFR 393.120 specifies that steel coils must be secured with a minimum working load limit chain and binder arrangement based on coil weight and position. Coils with eyes crosswise must have at least one chain through the eye plus tiedowns. Coils with eyes lengthwise require coil bunks/cradles. The total securement working load limit must equal at least 50% of the cargo weight.

Should I use a coil trailer or standard flatbed for steel coils?

Coil trailers are always preferred for round coils because they have built-in wells (cradles) that prevent rolling. Standard flatbeds can be used with aftermarket coil racks or wooden cradles, but this is a compromise solution. For coils over 20,000 lbs or multiple coils per load, a dedicated coil trailer is the safe and practical choice.

How do I estimate freight rates for steel shipments?

Steel freight rates are typically quoted per CWT (hundredweight) or per ton. Current market rates for flatbed steel freight range from $2.50-$5.00 per mile depending on lane, weight, and market conditions. For a 40,000-lb load traveling 800 miles, expect $2,000-$4,000. Contact carriers directly or use our rate estimator for current lane-specific pricing.

What should I do if steel arrives with rust or surface damage?

Note all damage on the bill of lading at delivery — do not sign 'clear' if there are visible issues. Take photographs immediately. Surface rust from inadequate tarping is the carrier's responsibility if tarping was specified. File a freight claim within 9 months (Carmack Amendment deadline) with documentation of the condition at origin and arrival.
