What is Coil Slitting? 

Coil slitting is a process involving equipment with rotary knives with which a full-width coil is cut into the customer engineered widths and required coil size and weight. With our expertise, we can use the incoming data we receive from the mills (i.e. chemistry, hardness, Tensile Yield Elongation), and put together a setup that will produce a precise width (capable of =/-.0025” in certain cases), as well as a clean edge with minimal burr.

We take our customer’s specific width and order a master coil from the mill. This allows us to minimize yield loss from edge trim and optimize the coil sizes to allow for longer run times on our customer’s equipment.

Coil Slitting Advantages & Benefits

When considering coil slitting services, it is essential to communicate your specific requirements, such as the desired mult width, material thickness, material type, and any additional processing or finishing needs. This information will help tailor services to meet your exact specifications.

At Alliance Steel, we offer a range of benefits and advantages that make us the ideal choice for your coil slitting needs. Coil slitting services offer several benefits, including:

1. Customization: Coil slitting allows for precise customization of mults to meet customers' specific width and thickness requirements. This flexibility benefits manufacturers and OEMS who need materials of various sizes for their production processes.

1. Increased Efficiency: By having metal coils slit into narrower mults, manufacturers can optimize material usage, reduce waste, and improve production efficiency.

1. Cost Savings: Coil slitting services can help minimize material waste, leading to cost savings for manufacturers. Additionally, obtaining precise mults widths reduces the need for further processing and minimizes scrap generation.

1. Improved Quality: Slitting services ensure uniform mults widths and smooth edges, enhancing the overall quality and consistency of the slit coil. This is crucial for industries with critical dimensions, such as automotive or appliance manufacturing.

1. Faster Turnaround: Working with a steel service center that offers coil slitting services can expedite the supply chain. The availability of slit coils can reduce lead times and provide faster turnaround for customers, enabling them to meet tight production schedules.

2. Types of slitting styles 

3. The two main styles of slitting are longitudinal and crosscut slitting. Let’s take a more in-depth look at these two types. 

   Longitudinal slitting

   Longitudinal slitting is most common for coil processing. The process involves cutting wide coils into narrower strips, typically in a continuous manner, where the cutting direction is parallel to the length of the original metal coil.
   
   The end product of longitudinal slitting is narrow strips or coils of material with customized widths. These strips are used in various applications, including roofing, construction, automotive components, and more.

   Crosscut slitting

   Crosscutting allows slitting sheets into smaller sheets or strips. The process involves cutting wide sheets or coils into shorter lengths to create individual pieces. In this instance, the cutting direction is perpendicular to the length of the original metal coil. 
   
   The end product of crosscut slitting is individual sheets or smaller lengths of material. These sheets are often used for packaging, manufacturing smaller parts, or any application that requires shorter pieces of material.
