Non-ferrous metals — aluminum, copper, zinc, brass, titanium — move in high-density loads that test weight limits before cube. This is a technically demanding niche with specific equipment and securement requirements, close ties to manufacturing, and a distribution network centered on metal service centers that most brokers overlook. Get the carrier side right and this market offers steady, repeat freight from industrial accounts.
What Non-Ferrous Metals Freight Includes
The commodity range in this market is broad, but a few categories dominate freight volumes:
Aluminum is the largest segment by volume. It moves in several forms, each with different equipment requirements:
- Aluminum coil: Rolled aluminum wound into large coils, used in auto parts, beverage cans, building products, and packaging. Dense and requires coil-specific securement.
- Aluminum extrusions: Long profiles (window frames, structural channels, heat sinks) extruded through dies. Often over 20 feet long, requiring flatbed or step deck.
- Aluminum sheet and plate: Flat-rolled aluminum for fabrication. Moved on flatbed with edge protection and proper blocking.
- Aluminum ingots and billets: Raw or semi-processed aluminum destined for casting or extrusion operations.
Copper moves primarily as:
- Copper rod and wire rod: Continuous cast copper rod, the feedstock for wire drawing operations. Extremely dense — copper weighs approximately 560 pounds per cubic foot.
- Copper coil and strip: Rolled copper for electrical components, plumbing fittings, and heat exchangers.
- Copper cathode: Refined copper in flat plate form, used as feedstock by rod mills.
Other non-ferrous commodities with meaningful freight volume include zinc ingots (for galvanizing and die casting), brass and bronze billets and rod (machined components and fittings), and titanium in bar, plate, and billet form for aerospace applications. Titanium is low-volume but extremely high-value, with corresponding requirements on carrier qualification and documentation.
The Weight-Cube Problem
The defining operational challenge in non-ferrous metals freight is that loads hit legal weight limits before they fill trailer space. This is especially pronounced with copper — a full pallet of copper rod can weigh 3,000–4,000 pounds. A partial truckload that looks half-empty volumetrically may already be at or near 44,000–48,000 pounds.
Aluminum, though lighter than copper, still presents weight management challenges. A standard aluminum coil can run 15,000–25,000 pounds. Multiple coils on a single load approach or exceed legal axle weights well before the trailer is physically full. Understanding the relationship between coil count, coil weight, and axle distribution is something carriers in this market know intuitively — and brokers need to understand to quote accurately.
Overweight permits are common in non-ferrous metals freight for loads that legally exceed standard limits. Brokers covering metals loads need to confirm whether permits are required, who obtains them, and what the transit time and route implications are. Loads that need permits routed through states with different weight allowances require advance planning.
Securement Requirements for Coil Freight
Coil loads — aluminum or copper — require specific securement that goes beyond standard flatbed practice. Federal regulations require coils to be secured against forward, rearward, and lateral movement, but the practical requirements go further than minimum compliance.
Coil racks and cradles are the standard solution. A coil rack (also called a coil cradle) is a V-shaped metal cradle that sits on the trailer deck and holds the coil in a stable orientation — either eye-to-the-side or eye-to-the-sky, depending on coil diameter and trailer configuration. Coils placed eye-to-the-sky (coil axis vertical) require different blocking than eye-to-the-side (axis horizontal).
Chains rated for the coil weight, positioned over and through the coil eye, are standard. Coil carriers know how to chain coils; flatbed operators without coil experience often do not. Vetting carrier experience with coil loads is a non-negotiable step before covering aluminum or copper coil freight. Ask carriers directly about coil experience, what securement equipment they carry, and how they position coils on the trailer.
Beyond coil, aluminum sheet and plate loads require edge protectors to prevent chain and strap damage to the aluminum surface. Scratched or gouged aluminum sheet can be a claim. Carriers who understand surface protection on aluminum loads are worth developing and keeping.
Flatbed vs. Specialized Equipment
Most non-ferrous metals freight runs on flatbed. The determining factors for when to move to specialized equipment are load length and height:
- Standard flatbed (48' or 53'): Aluminum sheet, plate, ingots, shorter extrusions, coil (with coil racks). The workhorse of metals freight.
- Step deck: Long aluminum extrusions (over 48 feet), taller stacked plate, some structural forms that need the lower deck height for legal clearance.
- Removable gooseneck (RGN): Rarely needed for non-ferrous metals, but occasionally for very large or heavy plate orders or specialized industrial equipment containing non-ferrous components.
- Coil trailer: A specialized flatbed with a recessed well designed specifically for coil freight. Common among carriers who specialize in steel and aluminum coil. These trailers carry coils without requiring separate cradles because the well itself positions the coil. Not all flatbed carriers have coil trailers — confirming whether a carrier runs a coil trailer vs. a standard flatbed with coil racks matters for securement planning.
The Mexico Angle: Aluminum and Auto Parts
Mexico is a significant origin and destination point for non-ferrous metals freight in North America. Several dynamics are worth understanding:
Aluminum for automotive manufacturing: Mexico's automotive sector — clustered in Guanajuato, Coahuila, Nuevo León, and Sonora — consumes large volumes of aluminum for engine blocks, transmission housings, wheels, and body panels. US aluminum service centers and mills ship aluminum coil and extrusions southbound into Mexico for auto parts manufacturing. This creates cross-border aluminum flatbed freight from Midwest service centers to border crossings and into Monterrey and other industrial centers.
Mexican aluminum and secondary metal producers: Mexico has domestic aluminum production through secondary (recycled) smelting operations. Secondary aluminum from Mexican plants moves northbound into US manufacturing supply chains. Cross-border non-ferrous freight is a two-directional flow.
Copper wire for electronics manufacturing: Mexico's electronics manufacturing sector — particularly in Baja California, Jalisco, and Chihuahua — is a major consumer of copper wire and rod. Wire drawing plants supply the electronics assembly operations throughout northern and central Mexico.
Brokers with cross-border capability and flatbed carrier relationships are well-positioned for this trade flow.
The Recycling Stream: Scrap Non-Ferrous
Scrap aluminum and copper represent a separate freight category from primary and semi-finished metals. Scrap non-ferrous moves from collection facilities, industrial scrap yards, and end-of-life processors to secondary smelters and refiners. This freight is often flatbed or open-top, is not weight-sensitive in the same way as finished product (scrap is often bulky and light), and the logistics chain is different — scrap dealers and processors rather than mills and service centers.
Scrap and primary freight can coexist in a broker's book but are different accounts with different buyer-seller relationships. Don't conflate them when prospecting.
Commodity Price Sensitivity
Aluminum and copper are exchange-traded commodities. LME (London Metal Exchange) aluminum prices directly affect how aggressively US mills and service centers manage inventory and ship product. When aluminum prices are rising, manufacturers and fabricators accelerate purchases, increasing inbound freight to service centers and processing facilities. When prices are declining or uncertain, buyers reduce inventory, slowing freight flows.
The same dynamic applies to copper, which tracks LME copper pricing. Because copper has lower domestic mine production relative to demand, copper price movements also reflect currency shifts and international trade flows.
Brokers don't need to trade futures, but understanding whether metals prices are in a rising or falling cycle helps explain why a service center account is suddenly moving aggressively or pulling back. It also provides a legitimate conversation entry point when prospecting metals accounts — demonstrating awareness of the market signals that drive their business.
The Aluminum Service Center Network
The aluminum supply chain in the US runs from primary production (smelters, with major capacity in the Pacific Northwest, Ohio, and Kentucky) through aluminum service centers to manufacturers and fabricators. Service centers are the critical freight account in this market.
A service center buys aluminum coil, sheet, and extrusions from mills, processes it (slitting, cutting to length, blanking, leveling), and ships it to manufacturing customers. Service centers are active, frequent shippers — they receive inbound from mills and ship outbound to manufacturers daily. Large service center networks like Metals USA, Ryerson, Olympic Steel, and Service Center Institute members operate distribution centers in industrial markets across the country, but hundreds of regional and independent service centers exist and are accessible accounts for brokers.
Prospecting service centers in automotive corridors (Michigan, Ohio, Indiana, Kentucky, Tennessee), industrial hubs (Texas, Pennsylvania, Georgia), and near major aluminum-consuming industries (packaging in Midwest, aerospace in Washington and California) provides a dense prospect list with real, repeatable freight needs.
Frequently Asked Questions
What equipment do I need carrier access to for aluminum coil?
The essential equipment for aluminum coil is either a dedicated coil trailer (a flatbed with a recessed well designed for coil) or a standard flatbed with coil racks/cradles. Carriers must carry chains rated for the coil weight and understand coil orientation — eye-to-the-side versus eye-to-the-sky — and the corresponding securement differences. Before covering an aluminum coil load with a carrier, confirm they have coil racks or a coil trailer, appropriate chains, and experience securing coil loads. A carrier who treats coil like standard flatbed freight will create claims.
How do commodity prices affect aluminum freight volumes?
When LME aluminum prices are rising or elevated, manufacturers buy forward and service centers replenish inventory aggressively — increasing freight demand. When prices are declining, buyers reduce purchase volume and inventory, reducing freight flow. The lag between price movement and freight impact is typically two to eight weeks, depending on contract and purchasing cycles. Brokers in this market benefit from tracking aluminum price trends as a forward indicator for account activity and as a credibility signal when talking to service center and mill contacts.
What's an aluminum service center and why do they matter for freight?
An aluminum service center buys aluminum in primary forms (coil, sheet, extrusions) from mills, performs value-added processing (slitting to width, cutting to length, leveling, blanking), and ships processed material to manufacturers. They are intermediate distributors in the aluminum supply chain. Service centers are among the most active and consistent flatbed shippers in the metals market — they receive inbound freight from mills constantly and ship outbound to manufacturers daily. Developing relationships with regional and national service centers in industrial corridors is the most direct path to steady aluminum freight volume.
Is non-ferrous metals freight mostly flatbed?
Yes. The vast majority of non-ferrous metals freight — aluminum coil, sheet, plate, extrusions; copper rod and coil; zinc ingots; brass rod — moves on flatbed or step deck. Dry van handles a small subset: packaged or containerized metals, some coil that is stretch-wrapped and palletized for indoor delivery, and smaller shipments of high-value specialty metals. Temperature-controlled equipment is not typically required for non-ferrous metals unless specific alloys have storage requirements (rare). Flatbed and step deck carrier relationships are the core of a non-ferrous metals freight book.
What securement knowledge do I need for metals freight?
At minimum, brokers covering metals freight need to understand coil securement (coil racks, eye orientation, chain positioning), the difference between coil trailers and standard flatbeds with cradles, edge protection requirements for aluminum sheet and plate, and the basics of how weight distribution affects legal compliance on heavy loads. You don't need to be a driver, but you need enough knowledge to ask the right questions when vetting carriers and to have a credible conversation when shippers ask about your carrier qualification process. Carriers who don't know how to secure coil loads will damage freight and create claims. Vetting securement competence before the first load is essential.
