Most brokers skip scrap freight. The equipment is specialized, the commodities are grimy, and the shipper network isn't obvious. That's exactly why it's worth learning. Less broker competition means better margins and longer relationships with shippers who aren't being called by every new agent in the industry.
What Scrap Metal Freight Actually Encompasses
Ferrous scrap — steel and iron — is the highest-volume category. It moves primarily from industrial generators and scrap dealers to electric arc furnace (EAF) mini-mills, which use scrap as their primary raw material instead of virgin iron ore. Companies like Nucor, Steel Dynamics, and Commercial Metals operate EAF mills across the US South and Midwest and need a continuous supply of scrap. Foundries casting iron and steel parts are another major end user.
Non-ferrous scrap — aluminum, copper, brass, stainless steel — moves to secondary smelters and refiners. Aluminum scrap is particularly active because secondary aluminum production uses roughly 5% of the energy required to produce primary aluminum from bauxite. Copper scrap flows to copper refiners and brass mills. These materials move in smaller volumes but at significantly higher commodity value per pound.
Industrial scrap is generated directly by manufacturers — stamping plants produce steel punchings and clips, machining operations generate turnings and borings, fabricators produce structural steel drops. Industrial generators often have ongoing contracts with scrap dealers who collect and consolidate material before it moves to the mill.
Post-consumer and municipal recycling creates mixed metal streams, crushed cars (shredder feed), and appliance scrap. Auto shredders are major scrap generators — they process end-of-life vehicles and sort the resulting metal by type.
E-waste is a growing category with its own regulations, but the metallic fractions — circuit boards, motors, wire harness — ultimately flow into the scrap metal stream.
Equipment: What Actually Moves Scrap
The equipment picture is specific and non-negotiable.
Open-top trailers are the workhorse of loose scrap movement — steel turnings, light iron, shredded scrap, and mixed metal go into open-tops loaded by crane or excavator with a grapple bucket. Drivers must understand that open-top loads often require tarping, and loading and unloading can take significant time.
End-dump trailers are used for some materials where the trailer can back into a pit and discharge without crane assistance. Common for certain types of prepared scrap.
Flatbeds handle baled and bundled scrap — auto body bales, baled aluminum, bundled steel plate drops. Baled scrap is compact and dense, making it ideal for flatbed movement when the material is prepared and stackable.
Roll-off containers handle smaller volumes, particularly in post-consumer collection, but the drayage component of roll-off operations is sometimes broker-accessible.
Know the weight reality: Scrap is one of the densest freight categories. A 53-foot open-top loaded with shredded steel will hit 80,000 lbs gross at roughly 20–22 feet of trailer length. Most scrap loads are weight-limited, not cube-limited. Brokers need carriers who understand legal axle weights and can manage scale stops. Overweight scrap loads are a compliance problem; understand gross weight limits and the state-by-state variability in permit requirements.
The Scrap Dealer Network
The industry has a tiered structure that matters for prospecting.
Small local scrap yards collect from walk-ins — contractors, homeowners, small industrial generators. They accumulate and sort material but typically sell to the next tier rather than shipping to mills directly.
Regional processors are the shippers that matter most to brokers. They have sufficient volume to move full truckloads regularly, they maintain relationships with mills and smelters, and they need reliable carrier coverage. These are the accounts worth targeting.
Large scrap brokers and trading companies — companies like Sims Metal, OmniSource (Steel Technologies), Commercial Metals, and others — are high-volume players who manage complex logistics across multiple facilities. Getting into these accounts is harder but the freight volume is significant.
Industrial generators are an often-overlooked source. A large stamping plant that generates 500 tons of steel scrap per month is a shipper in its own right. The scrap gets picked up by a dealer, but sometimes the generator controls the freight decision.
Commodity Price Sensitivity
Scrap freight volume tracks steel mill production. When steel prices fall and mills reduce production, scrap demand drops — yards accumulate inventory and outbound shipments slow. When steel demand picks up, mills accelerate purchasing and scrap freight surges.
The practical implication: scrap freight is cyclical at the macro level but the individual shipper relationships are worth maintaining through the cycle. Shippers who trust you in the down market will give you volume when things turn up.
Aluminum and copper scrap track their respective commodity markets. Copper is particularly price-sensitive — the spread between US scrap prices and global prices drives whether material moves domestically or goes to export.
The Export Angle
The US is one of the world's largest exporters of ferrous scrap. Turkey, India, and historically China are major buyers of US scrap steel. This creates a geography of port-adjacent freight — scrap from the Midwest and Southeast moves to Gulf Coast and East Coast ports for containerized export or bulk vessel loading.
Port-adjacent scrap freight has different dynamics: the destination is a port terminal or export facility, timing is driven by vessel schedules, and the counterparty may be an export broker rather than an end-user mill. Building relationships with export-focused scrap dealers near major ports (Houston, Baltimore, New Orleans, Newark) opens a distinct set of lanes.
How to Find Scrap Accounts
Industrial manufacturers are your first call list. Any large manufacturer — auto parts, appliances, steel fabrication, HVAC components — generates captive scrap. Look up manufacturing employers in your target region and start with operations that use steel, aluminum, or copper in their processes.
Scrap yards and processors are publicly listed with the Institute of Scrap Recycling Industries (ISRI). Their member directory gives you a starting list of legitimate processors by region. State recycling and solid waste associations also maintain directories.
Cold calling scrap accounts is straightforward once you understand the business. Ask about their outbound volumes, what mills or smelters they ship to, and what equipment they use. Show that you understand the weight limitations and open-top carrier requirements — that immediately separates you from brokers who are guessing.
Frequently Asked Questions
What equipment do I need for scrap metal freight?
Open-top trailers handle the majority of loose, shredded, or mixed scrap. Flatbeds cover baled and bundled material. End-dump trailers are used for some prepared grades. Weight management is critical — ferrous scrap is extremely dense and most loads are weight-limited, not cube-limited. Make sure your carriers understand gross weight limits and axle configurations for heavy loads.
How do commodity prices affect scrap freight volumes?
Ferrous scrap tracks steel mill production. When steel demand is strong and EAF mills are running at high utilization, scrap purchasing accelerates and outbound freight volumes increase. When steel prices fall and mills cut production, scrap accumulates at yards and fewer loads move. Non-ferrous scrap tracks aluminum, copper, and other metal commodity markets independently. Brokers who stay in this vertical through the cycles get the volume when it comes back.
Is scrap freight regulated differently from regular freight?
Most scrap moves under standard carrier authority. However, some categories of scrap — particularly e-waste — have specific state and federal regulations around transport and disposal, and hazardous scrap (oil filters, automotive fluids, certain industrial residues mixed with scrap) may trigger hazmat requirements. Standard ferrous and non-ferrous scrap is not hazmat. Always confirm with the shipper what's in the load; contaminated scrap can create liability issues.
How do I find scrap dealers and recyclers to prospect?
The Institute of Scrap Recycling Industries (ISRI) publishes a member directory searchable by commodity and location. State-level recycling industry associations are another source. Industrial manufacturers are a less obvious but valuable channel — any company that uses steel, aluminum, or copper in production generates scrap and often works with a dealer who controls the outbound freight.
What's the difference between ferrous and non-ferrous scrap freight?
Ferrous scrap (iron and steel) is high-volume, moves primarily to EAF mini-mills and foundries, and is the densest and heaviest category — open-top and weight management are the main logistics concerns. Non-ferrous scrap (aluminum, copper, brass, stainless) moves to secondary smelters and refiners, at lower volume per shipper but higher commodity value. Non-ferrous is more likely to move on flatbed in baled or consolidated form and is more sensitive to export market dynamics.
