Our Processes: Slitting

packaged slit coil at OFR MetalsIn part two of our processes series, we will discuss slitting. Slit coil is used for a variety of end products. Some of the more common include: HVAC duct, lighting fixtures, architectural trim, roof drain pipes, and many more.

So what does the slitting process entail? Well, the simplest definition is… slitting is a process where steel coils are fed through a slitting machine and cut into narrower widths.

But there is more to it than just making smaller coils.

Slitter Machines

slitting machine at work at OFR MetalsMachines used to create slit coil typically consist of stations for uncoiling, slitting, and recoiling. The thicknesses and widths that a coil can be cut to depend on the machine. Here is a list of our branch capabilities.

Machines used for the slitting process can run both ferrous and non-ferrous material and depending on the machine, may be used for sheet metal or rolled coils. At Metalwest, our machines process steel coils.

Blades used for slit coil vary depending on the job requirements. Different blades are used based on the gauge and type of material as well as the tolerances specified by the customer.

The Slitting Process

Quality check by our slitting team at OFR MetalsCoil slitting, or roll slitting, is the process in which a large master coil is uncoiled and sent through a set of two circular wheels, or shears. These shears are set at a predetermined width and cut the coil into a series of narrower rolls. The narrow rolls, now called strands, are then hand-measured by the teams on our slitter machines to ensure the customer specifications are met and tight tolerances are held.

After the quality check by our team, the strands are recoiled and packaged to produce customer-specific slit coils.

At Metalwest we can process slit material in a variety of gauges and widths to meet the demands of our customers. To find out which of our locations slit material and what the different tolerances are, contact your sales representative.

Our Processes: Leveling / Cut-to-Length

Lately, we have discussed how many of our products are made and what they are used for. But we haven’t discussed how the coil from the mill becomes a swing set, an HVAC duct system, a food prep table, or a horse trailer. So, today we are going to talk about one of the many processes it takes to turn a coil into an end product. At Metalwest we process the coils we receive from mills and make them into ideal material for our customers. While it may not seem like much to most people, cutting a coil into smaller sheets can mean all the difference for customers who do not have the capability to handle large coils or need to save on processing times. That brings us to our first processing capability. This five-part series will delve into the different processes we offer our customers. The first is leveling / cut-to-length. The simple overview of a leveling / cut-to-length line is that it converts coil into sheet. But it does much more than that.

leveling lineLeveling

When a coil is run through a leveling / cut-to-length line the first step is to, well, level it. Metal can be easily bent, shaped, and formed-which is a good thing for many customers-but because of this, when the metal is wound into a coil at the mill it tends to hold that curved shape when the coil is unwound at a service center. So, the leveler’s job is to straighten the coil so it can later be cut into flat sheet.

The leveling technology we use is able to hold tight tolerances. This means we can process material to our customer’s specifications. The corrective levelers provide shape correction for squared cut-to-length material.

Reduce Overall Scrap

Because the technology we use can process tight tolerances it also means reduced scrap for not only us, but our customers as well. Reducing scrap costs is a top priority for many of our customers. Even a small reduction of those costs can have a large impact on our customers’ success. And we definitely believe our customers’ success is our success.
