What is Steal Slitting?

The purpose of slitting metals (such as steel) is to cut large rolls or coils down into narrower rolls. Referred to as the master roll by steel slitting companies, this large coil is then run through a slitting line, which converts it to several rolls with smaller widths. This can be done incredibly efficiently and precisely, which makes it great for projects with tight tolerances.

Slitting Services for Sheet Metal & Coils

High-quality circular blades are used in steel slitting services, often called knives, to slit large coils of steel. The knives’ positions can be adjusted to cut the metal into different width strips for a desired size.

The general slitting process in sheet metal takes the coil, unrolls it, slits the metal, then rolls it back up again, giving you several narrow-width slit coils for your project. Slitting your steel is an efficient and fast way to get the uniform measurements you need quickly, and can help make further processing easier. If you’re ready to get started, request a quote today.

STEEL SLITTING FAQS

Coil slitting is a process utilized across many industries: from construction to farming and even oil and gas projects. Here are some examples:

  • Construction: Slit steel is used to manufacture ducts, vents, and other components of heating, ventilation, and air conditioning (HVAC) systems.
  • Agriculture: Steel strips are used in creating silos, grain bins, and storage tanks, ensuring safe and durable storage of agricultural products.
  • Infrastructure: Slit steel is utilized in the production of poles and towers that support electrical lines, telecommunications equipment, and lighting in infrastructure projects.

  • Uncoiler: the part of the line that unrolls the metal and feeds it into the slitter
  • Slitter: the blades that cut the metal into narrower bands
  • Recoiler: what takes the narrow bands and rolls them back up into new coils

If a slitting line doesn’t have high-quality tooling or the metal being slit is low quality, there can be issues with the finished product. Slitting without consideration of steel type and grade can also lead to this. Poor edge quality, edge burr and wave, crossbow, camber, and knife marks are all potential problems that can be seen if not done by a reputable metal processor with high-quality tooling.

Steel slitting companies use different gauges are used to categorize steel depending on how thick (and difficult to slit) the material is.

  • Light Gauge: used for materials between 0.15mm and 4mm thick, highest precision.
  • Medium Gauge: used for materials between 1mm and 10mm thick, precise and tough.
  • Heavy Gauge: used for materials between 8mm and 20mm thick, toughest applications.

Metal slitting allows a much larger roll of steel (usually produced as large as possible to maximize material and labor efficiency) to be separated into several narrower coils to fit project specifications. These narrower pieces of sheet steel can be used for a wide range of applications, from drain pipes to HVAC ducts.
