Cutting and rolling are two different methods of shaping steel. While cutting uses drills, saws and other tools to slice, shape and size the material, rolling performs the same task by squeezing the steel between two large rolls. Though there are similarities between the two, each has its own advantages that make it suitable for different applications.
Cutting is typically used to shape larger pieces of steel. It can be used to cut steel plate in half, to shape steel beams, rods and other structural components, and even to cut tiny pieces for modern electronics. The advantage of cutting steel is its precision; with proper cutting tools, any shape can be achieved with exact precision in a relatively short time. Furthermore, with proper cutting tools, very little waste is created when cutting steel, making it a cost effective method for shaping steel.
Rolling is different from cutting in that steel is not cut into individual shapes, but rather squeezed through two rolls to create its desired shape. This is done slowly and with great precision, allowing for a range of shapes and sizes to be created. Rolling tends to be used for very large pieces or for many identical pieces that need to be the same size and shape. This method is used to create rods, channels, P-shapes, I-shapes and various Steel Profiles.
The advantage of rolling is that it can create highly precise shapes and sizes that may be difficult or impossible to get through cutting. In addition, rolling can also be used to straighten steel as well as to reduce its thickness as it passes through the two rolls. Although cutting is more precise and may in some cases be more cost effective, rolling is capable of achieving the same results in a fraction of the time and with minimal waste.
In conclusion, cutting and rolling both have their uses when shaping steel. Cutting is typically used for small, precise pieces, while rolling is usually used for larger applications. Both offer their own advantages, and the best method for shaping steel depends on the size of the piece and the end goal. Each method offers its own strengths, with cutting offering the greatest precision and rolling allowing for larger pieces to be shaped with fewer tools.
