Our Processes: Slitting

In 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

Machines 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

Coil 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.
