Why Cut-to-Length Steel Requires a Different Approach to Load Securement Than Coil

Many cut-to-length and blanked steel operations continue using securement practices developed around longstanding material-handling and shipping routines.

Dunnage gets set where the forklift needs clearance, not where the stack needs restraint. Banding gets standardized around familiar bundle configurations, not necessarily around the geometry and handling conditions of each load. Nobody re-engineers it, because nothing about the load looks different on the shipping paperwork.

Under federal cargo securement rules, however, coil and flat steel are not treated the same way.

Key Takeaways:

• The commodity-specific coil rule generally does not apply to flat steel: 49 CFR 393.120’s engineered requirements, including cradles, prescribed tiedown angles, and a ban on nailed-only securement, apply specifically to metal coils. Cut-to-length sheet, blanks, and plate default to the general cargo rule instead.
• The general rules establish performance criteria, working load limits, and tiedown requirements, but they do not prescribe a load-specific restraint design for flat steel: Among other requirements, the general rules establish minimum tiedown requirements based on cargo length and specify aggregate working load limit requirements for the securement system. Those requirements do not, by themselves, prescribe dunnage or restraint placement based on a particular stack’s weight distribution or load geometry.
• This is a live enforcement priority: CVSA named cargo securement the vehicle focus area for the May 2026 International Roadcheck, on the back of more than 34,000 cargo-related violations recorded in 2025 alone.
• Securement problems may become visible in transit or at delivery, even when contributing decisions involving dunnage, packaging, or load preparation were made before departure: Uneven dunnage, loss of bundle integrity, and blocking that does not account for load geometry or anticipated movement.
• The fix doesn’t require new equipment: Engineering dunnage placement, blocking direction, and edge protection to the load’s actual geometry is a design decision, applicable to lines already running.

Vehicle cargo securement remains the responsibility of the motor carrier and driver under applicable regulations. But decisions made before loading, including how steel is unitized, supported, blocked, and prepared for shipment, can materially affect how effectively that cargo can be secured for transportation.

Why the Federal Coil Rule Doesn’t Follow Steel Once It’s Cut to Length

Steel coil carries a regulatory structure that cut-to-length steel doesn’t 49 CFR 393.120 establishes commodity-specific securement requirements that address the distinct movement risks associated with metal coils. Flat steel, once cut, blanked, or processed into plate, is generally subject to broader cargo securement requirements that do not prescribe a flat-steel-specific restraint system.

What the Coil Rule Actually Requires

Coil gets its own rule because it fails in a specific, dangerous way. Under 49 CFR 393.120, a coil shipment has to be secured with:

• Specific combinations of bunks, wedges, chocks, blocking, bracing, and tiedowns depending on the coil’s orientation and loading configuration
• Specific securement configurations based on the orientation of the coil’s eye and its position on the vehicle
• A restraint system sized against rolling motion, not just forward and lateral sliding
• An explicit ban on nailed blocking or a nailed wood cradle as the sole means of securement

That level of prescription exists because an improperly secured coil rolls, not just slides, and regulators chose to legislate against that specific physics directly, the same way they wrote dedicated rules for paper rolls and concrete pipe.

What Flat Steel Defaults to Instead

Cut-to-length sheet, blanks, and plate are not addressed by the metal-coil-specific provisions and are generally subject to the applicable general cargo securement requirements. Among other requirements, the general rules establish minimum tiedown requirements based on cargo length and specify aggregate working load limit requirements for the securement system.

Those requirements can be satisfied without prescribing where dunnage or restraint should be positioned for a particular load’s weight distribution and geometry.

That math is built to withstand specific, real forces. Under 49 CFR 393.102, a securement system has to hold cargo against:

• 0.8g forward, the force of hard braking
• 0.5g rearward, the force of sudden acceleration
• 0.5g laterally, the force of a sharp turn

Those performance criteria establish the minimum acceleration forces a cargo securement system must be capable of withstanding, but they do not, by themselves, prescribe a load-specific restraint design based on a particular stack’s geometry or weight distribution.

Cut-to-length and blanking are standard processing lines that most steel service centers already run alongside coil, not a niche add-on. That means the securement gap applies to an already-common part of the product mix, not an edge case. These operations routinely ship products that fall outside the coil-specific provisions and instead must be secured under the applicable broader cargo securement requirements.

The Gap Is Now a Named Enforcement Focus

CVSA named cargo securement the vehicle focus area for the 2026 International Roadcheck, on the back of more than 34,000 cargo-related violations recorded in 2025, roughly 11% of all vehicle out-of-service findings that year.

An out-of-service violation can create hours of unplanned downtime on a route, reinforcing why load preparation and securement practices deserve attention before the vehicle leaves the facility.

Where Minimum Compliance and Load-Specific Engineering Differ

Meeting applicable working load limit and tiedown requirements does not, by itself, mean a load preparation system has been designed around the specific geometry and weight distribution of the product being shipped. Regulatory compliance and load-specific engineering address related but distinct considerations.

Dunnage That Solves for Forklift Access, Not for Where the Load Wants to Tip

Dunnage on a plate or heavy-gauge sheet stack usually gets placed to keep the load off the deck and accessible to a forklift. That’s a material-handling decision, set once and rarely revisited.

A mixed-gauge order changes what that default needs to protect against:

• Forklift-clearance dunnage keeps the load accessible, but doesn’t restrain it against movement
• A mixed-gauge stack can have a center of mass that differs significantly from the stack’s geometric center, particularly when heavier material is unevenly distributed across the load
• Standardized dunnage placement and minimum tiedown requirements do not necessarily account for how weight is distributed within a particular stack

The result can be a load that meets applicable securement requirements while its support and load preparation have not been specifically designed around the product’s weight distribution. Under hard braking, uneven support or poorly positioned restraint can increase the potential for load movement.

Bundle Integrity and Vehicle Securement Solve Different Problems

Banded bundles present a related but different problem:

• Bundling and vehicle securement perform different functions. Internal banding may help maintain bundle integrity, while the vehicle’s cargo securement system must independently meet applicable regulatory requirements. Both can be affected by load geometry, sharp edges, settling, and movement during transportation
• Unprotected steel edges can abrade, damage, or concentrate stress on certain securement components during transportation

Over the course of transportation, settling, vibration, and contact at unprotected edges can affect bundle integrity or securement components, depending on the system being used. When that load arrives shifted or damaged, or gets flagged at a roadside inspection, the driver or the carrier is often the first thing anyone questions. The decisions made before the truck left the dock rarely come up.

Engineering the Load-Specific System Flat Steel Requires

Coil-specific requirements address several critical securement functions through prescribed configurations based on the coil’s orientation and position on the vehicle. Flat steel presents different load characteristics, requiring support, movement restraint, and securement component protection to be considered in the context of the specific product and load configuration.

Dunnage Engineered to Where the Load’s Weight Actually Sits

This starts with understanding how weight is distributed across the product configurations the line routinely ships.

In practice, that means:

• Dunnage specifications developed around representative product configurations, including variations in gauge, dimensions, and weight distribution
• A documented placement standard for each product configuration a line runs
• That standard held to on every run, the same way any other packaging spec on your floor already is

No new equipment required on the processing line. This is a placement standard, not a purchase.

Blocking and Bracing Sized to Resist the Load’s Direction of Travel

Coil securement blocks against rolling because that’s the direction a coil actually moves once it comes loose. Flat steel moves differently:

• Forward, under the 0.8g force a hard stop can generate
• Laterally, through a sharp turn

Where blocking or bracing is used, its location and design should correspond to the anticipated directions of cargo movement and the forces the securement system must resist. A load engineered this way resists the exact failure mode a hard stop produces, instead of relying on tiedown tension alone to arrest movement that’s already started.

Edge Protection That’s Already Required and Routinely Skipped

Federal regulations (49 CFR 393.104) require edge protection where a tiedown would otherwise be subject to abrasion or cutting at the point of contact with the cargo. A proper edge protector:

• Distributes tiedown force across a wider area of the load
• Helps protect the tiedown from damage at contact points and can help distribute force at the load interface
• Lets the tiedown be tensioned properly instead of binding partway through

It can also be easy to overlook because a load may appear fully secured at the dock without it. In some cases, the consequences may not become apparent until transportation is underway and the securement system has been exposed to vibration, movement, and repeated loading.

These three are design decisions, not purchases: made once for a given product configuration and held to consistently, the same way every other packaging spec in your program should be.

Start With the Line That Added Capacity Without Anyone Revisiting Securement

The right place to test this is a single line, not the whole facility: the specific cut-to-length, blanking, or plate line still running whatever securement approach it inherited before that equipment came online, left unchanged because nothing has gone wrong with it yet.

A focused review on that program covers three things:

• Current securement practice against actual product geometry. What’s being used today, checked against the real gauge, length, and weight distribution of what that line actually ships, not what it shipped when the practice was first set.
• Weight distribution across a representative run. Where the mass center actually sits on a typical mixed-gauge or mixed-length order, not the load’s geometric center.
• The handling path from end of line to delivery. How far the load travels, how many stops, and what braking and turning conditions it’s realistically exposed to before it reaches the customer.

That review can identify where standardized load preparation practices may not fully account for the geometry, weight distribution, and handling conditions of the products being shipped. A history of incident-free shipments does not necessarily mean those practices cannot be improved as product configurations and operating conditions change.

Engineering Load Preparation Around the Flat Steel You’re Actually Shipping

Conner Industries designs dunnage, blocking, and bracing systems engineered to a load’s actual geometry and handling path, not to a generic weight-based standard. That capability applies directly to a service center whose product mix has shifted from coil toward cut-to-length, blanking, or plate processing, whether that shift happened last quarter, five years ago, or alongside a broader switch to domestic steel sourcing.

If your cut-to-length services are still running on the securement approach your line used when it only shipped coil, that program is the place to start. Contact Conner Industries for a review of your current dunnage, blocking, and bracing design against the flat steel you’re actually shipping today.
