What Is Toll Slitting?

Toll slitting is a metal processing service where we cut your wide-width steel coils into multiple narrower strips according to your specifications. You provide the master coil, we slit it to your exact widths, recoil it, package it, and return it to you—ready for your production line, inventory, or customer delivery.

This process allows service centers, distributors, and manufacturers to:

  • Purchase larger, more cost-effective master coils from mills

  • Convert wide coils into custom widths without capital investment in slitting equipment

  • Outsource processing to free up facility space and labor

  • Respond quickly to customer orders requiring specific slit widths

  • Minimize inventory by slitting only what you need, when you need

Our Steel Slitting Capabilities

Materials We Process

Collier Metals slits a full range of carbon steel grades and surface finishes:

Hot Rolled Steel – Also known as hot rolled black or HR black, this is as-rolled carbon steel without additional surface treatments. Common grades include A36, ASTM A1011 Commercial Quality (CQ), HSLA grades, and structural grades. Hot rolled steel is ideal for structural applications, tube mills, and general fabrication where surface finish is not critical.

Hot Rolled Pickled & Oiled (HRPO) – Hot rolled steel that has been descaled in an acid bath (pickled) and coated with a rust-inhibiting oil. HRPO provides a cleaner surface than hot rolled black, making it suitable for applications requiring paint adhesion, welding, or improved formability. This material is commonly used in automotive parts, appliances, and stamped components.

Galvanized Steel – Steel coated with a zinc layer for corrosion protection. We process various coating weights including G40, G60, and G90 (measured in oz/ft²). Galvanized steel is widely used in HVAC ductwork, roofing, outdoor equipment, and any application requiring weather resistance.

Cold Rolled Steel – Steel processed at room temperature for improved surface finish, tighter dimensional tolerances, and enhanced strength. Cold rolled steel is used in precision parts, appliances, automotive components, and applications where appearance and exact dimensions matter.

The Toll Slitting Process at Collier Metals

Step 1: Coil Receiving & Inspection

Your master coils arrive at our facility via truck, rail, or stored in our warehouse. We verify coil identification, dimensions, and condition upon receipt. Any visible defects or discrepancies are documented and reported immediately.

Step 2: Coil Staging & Line Setup

Coils are staged near the slitting line using our overhead cranes (up to 250-ton capacity). Our operators program the slitting line with your exact width specifications, accounting for material thickness, trim requirements, and final coil inner diameter preferences.

Step 3: Precision Slitting

The master coil is loaded onto the uncoiler and fed through our multi-knife slitting arbor. Circular slitting knives cut the coil longitudinally into your specified widths as it passes through the line. Material tension is carefully controlled to prevent camber and ensure straight edges.

Step 4: Recoiling & Inspection

Each slit width is individually recoiled onto separate mandrels. Operators monitor coil tension, winding tightness, and edge alignment throughout the process. Final coils are inspected for width accuracy, edge quality, and proper winding.

Step 5: Banding, Packaging & Labeling

Finished coils are banded with steel strapping at multiple points to prevent unwinding during transport. We apply custom labels with your specified information: coil ID, width, gauge, weight, heat number, and any other required data. Protective wrapping or skid packaging is available upon request.

Step 6: Delivery or Storage

Finished coils are either delivered directly to your facility, shipped via common carrier, or stored in our warehouse until you're ready for them.

Toll Slitting vs. Buying Slit Coils: When Does Toll Processing Make Sense?

Toll slitting is ideal when:

  • You already own master coils and need custom widths

  • Your required widths aren't standard inventory items

  • You want to control material sourcing and pricing

  • You need specific mill certifications or heat numbers

  • Order volume doesn't justify equipment investment

  • You want to minimize inventory by slitting as-needed

Buying pre-slit coils makes sense when:

  • You need standard widths immediately

  • Order quantities are smaller (part of a coil)

  • You prefer simplified purchasing (we own the master coil)

  • Material specification is flexible

We offer both options—toll processing your coils or selling you slit coil products from our inventory. Many customers use a combination approach depending on their needs.

Frequently Asked Questions About Toll Slitting

What is toll slitting?

Toll slitting is a service where you provide the master coil and we cut it into narrower strips according to your specifications. "Toll" means you pay for the processing service while retaining ownership of the material throughout.

What is the maximum coil weight you can slit?

Our 72" slitter can process entry coils up to 60,000 lbs. Exit coils (after slitting) can be wound up to 45,000 lbs per coil.

What is your minimum slit width?

Our minimum slit width is 2 inches on the 72" slitter. For widths narrower than 2 inches, our 36” slitter will accommodate widths down to .5 inches—contact us to discuss your requirements.

What tolerances do you hold on slit width?

We hold standard commercial tolerances of ±0.005" on slit width. Tighter tolerances may be achievable depending on material thickness and width—discuss your requirements with our team.

How many cuts can you make from a single master coil?

This depends on material gauge and the width of your master coil. For example, on 1/4" gauge material, our 72" slitter can make up to 11 cuts. On 1/8" or thinner, we can make 18+ cuts. The number of cuts also depends on minimum slit width requirements and trim waste.

Do you process stainless steel or aluminum?

No, Collier Metals specializes exclusively in carbon steel processing—hot rolled, HRPO, galvanized, and cold rolled. We do not process stainless steel, aluminum, or other non-ferrous metals. This focus allows us to maintain equipment specifically optimized for carbon steel.

What edge quality can I expect?

Our slitting knives are maintained to produce clean, burr-free edges suitable for most applications including stamping, roll forming, and tube production. Edge quality depends on material type and gauge—we can discuss edge conditioning options for critical applications.

Can you apply oil or protective coating to slit coils?

Yes, we can apply rust-preventive oil or protective film to slit coils upon request. This is particularly important for bare steel (hot rolled black and HRPO) that will be stored or shipped before use.

What inner diameter (ID) options are available for recoiled strips?

Our standard exit coil IDs are 20" and 24". If you have specific ID requirements for your processing equipment, let us know—we may be able to accommodate.

Do you provide mill test reports (MTRs)?

Yes, we maintain mill certifications for all coils we process. Mill test reports showing chemical composition and mechanical properties are available upon request at no charge.

Can you slit coils with special surface finishes or coatings?

Yes, we regularly process galvanized, galvannealed, and oiled materials. For pre-painted or specialty coatings, contact us to discuss material specifications—some coatings may require special handling or knife setups.

What if there are defects in my master coil?

We inspect all coils upon receipt and document any visible defects before processing. If defects are discovered during slitting (internal defects not visible on the outside wraps), we stop processing immediately and contact you to discuss options. We are not responsible for pre-existing material defects but work with you to minimize waste and find solutions.

Can you package and label coils to my specifications?

Absolutely. We accommodate custom packaging requirements including specific banding patterns, eye-to-sky or eye-vertical orientation, skid mounting, protective wrapping, and custom labeling with your specified information (coil ID, width, weight, heat number, customer PO, etc.).

How quickly can you process my coils?

Standard turnaround is 3-5 business days from the time coils arrive at our facility. Rush service (24-48 hours) is available for urgent orders when line capacity permits—contact us to discuss your timeline.

Do you offer warehousing before or after slitting?

Yes, our 200,000 sq ft warehouse can store master coils before processing and hold finished slit coils until you're ready for delivery. This is particularly useful for managing inventory flow and coordinating delivery schedules.

How do I get my coils to your facility?

Coils can be delivered to our Atlanta facility by truck (your fleet or common carrier), by rail via Norfolk Southern, or you can arrange delivery as part of your mill order. We're located just off I-20 with easy truck access.

Can you deliver the finished slit coils to my facility?

Yes, we offer delivery services throughout the Southeast using our in-house truck fleet. We also coordinate nationwide shipments with trusted common carriers. Many customers choose to pick up with their own trucks.

What payment terms do you offer?

Payment terms are established based on credit application and references. We work with both established customers on account terms and new customers on prepay or COD arrangements. Contact our sales team to discuss terms.

Do you slit coils on a contract basis or per-job basis?

We accommodate both. Many customers have ongoing toll processing agreements with scheduled deliveries and contracted pricing. Others send coils as-needed on a per-job basis. We're flexible to match your business model.

Can you handle hot band (as-rolled) coils directly from the mill?

Yes, we frequently process hot band coils. These are typically heavier gauge, wider width coils that come directly from hot strip mills before any additional processing like pickling or cold rolling.

What makes Collier Metals different from other toll slitters?

Our key differentiators include: (1) Dual slitting lines including a 72" heavy-duty line with 60,000 lb capacity, (2) Integrated logistics—rail transloading, warehousing, and delivery all on-site, (3) Atlanta location providing central Southeast access, (4) Focus exclusively on carbon steel allowing specialized expertise, and (5) Fast turnaround with experienced operators.
