Metal fabricators have to consider a wide range of variables when it comes to any custom project. From the type of metal being used to the dimensional specifications of that metal to the logistics of forming it, finishing and beyond, everything must be considered upfront.
When the fabrication process calls for plate and bar rolling, there are even more variables to consider. Steel fabricators in Phoenix, AZ need to understand the force dynamics at work to make sure they’re properly shaping the metal they’re working with.
Factors to Consider
Let’s take a look at some of the factors that go into plate and bar rolling, and why these things are such a necessity to consider:
- Metal thickness: Understanding the metal thickness enables fabricators to gauge the tensile strength of the metal. It can also dictate how much force is required to be exerted upon the plate or bar by a rolling machine in order to affect a precise angle.
- Type of metal: The alloy you’re working with makes all the difference in terms of how it’s handled and formed. Different alloys have different ductile properties and tensile strength points, which factor heavily into how much force is needed to act upon them.
- Rolling angle: What degree of curvature is needed for the finished product to meet spec? This dictates the rolling angle that will need to be set as the plate or bar rolling machine begins to work. Verifying this measurement upfront means not having to re-roll metal, which can distort or compromise it.
- Force: This is the level of force that needs to be exerted upon a plate or bar to properly curve it to the angle set by your rolling machine. Knowing and maintaining consistent force will ensure a precise bend is made.
- Arc measurement: Think of every angled bend as part of a circle. No matter what angle you bend at, it will eventually make a complete circle if left to bend long enough. Knowing how much of that circle you need to bend is the arc measurement. For example, you need to know upfront that you need 6’ of a plate rolled at 30 degrees, which enables you to account for the total length of the plate, as well as any excess.
Each of these factors plays a critical role in the rolling process and has a distinct effect on how accurately bending is completed.
Measure Twice, Roll Once
As mentioned, having to re-roll sheet metal isn’t usually an option for many projects, and it can cause all sorts of problems if attempted. To avoid this predicament, it’s paramount to measure precisely… then measure again to ensure it’s accurate. Precision equates to an exceptional finished product, which can only be achieved if all of the factors and variables above are taken into account first.
Upon closer inspection, it’s easy to see why plate and bar rolling need to be undertaken by experienced steel fabricators in Phoenix, AZ. There’s a lot more than just feeding metal into a machine, pressing a button and getting great results!
