How to Cut Steel Plate?

Whether you’re a professional machinist or a DIY enthusiast, learning how to cut steel plates is an essential skill. A steel plate can be difficult to work with because it is thick, heavy, and hard. But if you have the right tools and approach, you can easily get the job done. This guide will go over the different methods for cutting steel plates with precision and ease.

Using a Circular Saw or Grinder

A circular saw or grinder is one of the most common tools for cutting steel plates. It’s relatively inexpensive, easy to use, and produces excellent results. Wear protective clothing and goggles when using a circular saw or grinder, as sparks will be flying in all directions. Start by marking the line you want to cut on the steel plate with a pencil or marker. Then, place your circular saw/grinder on top of the marked line and begin cutting. To ensure accuracy, keep your tool level at all times while not applying too much pressure so that your tool doesn’t slip off the marked line.

Using a Torch

Another popular method for cutting steel plates is with a torch. This method requires some practice as it takes skill to control the size of the flame while keeping it steady at all times during the entire process. Before starting this process:

  • Ensure that your workspace is clear of any flammable material, such as paper or wood, and any other combustible items that could catch fire during this process due to sparks flying around during cuts.
  • When using a torch for cutting steel plate, start by marking the desired line with chalk powder or soapstone powder before preheating the area for it to be easier for oxygen-acetylene combination flames to cut through without difficulty or creating too much heat buildup in one place that would cause warping in your piece after cooling down from cutting process completion. The preheating should be done slowly until reaching about 500 degrees Celsius before continuing into full-on cutting mode as soon as temperatures are adequate.
  • Remember not to forget safely secure down all parts before beginning so that they remain stationary throughout the entirety of the procedure.

Using Plasma Cutting

Plasma cutting is another option for those who need precise cuts but don’t want to invest in expensive machinery like waterjet machines—though plasma cutters are still quite pricey compared to other options like abrasive saws or grinders—and require more practice than other options like torches since they produce higher temperatures than regular torches which can create difficulties controlling both temperature levels & speeds simultaneously. Fortunately, plasma cutters come equipped with safety features such as auto-ignition shutoff & cooling systems which help minimize potential dangers associated with using them properly when learning how to operate them safely.


Cutting steel plates can seem daunting at first; however, if you have access to (or know where to get) the right tools, proper attire, knowledge, & training necessary to stay safe throughout the entire process, then it shouldn’t take too long learning how to use these various methods accurately whether working professionally operating DIY projects around the home. With a little bit of patience & determination, you soon have no problem cutting through those tough steel plates easily! Good luck! ​​​​
