Where to Start Depends on Why You Are Here
Four common situations, and the reading order that saves the most time in each.
- 01
If you are buying your first machine
Start with what the process actually is and what a line consists of, then move to machine selection. The two pieces that change the most decisions are understanding that the profile decides the station count, and understanding that the front end — decoiler and leveling — decides whether the finished profile comes out straight.
- 02
If you are replacing or adding a second line
The useful questions are different: which profiles can share a base machine on interchangeable cassettes, and whether a second narrower line or one wider line with quick changeover gives you better changeover economics. Start from the profile family you already run rather than from machine size.
- 03
If you are an engineer specifying a section
Go straight to the profile references — purlin section geometry, roofing profile conventions and deck geometry. The design logic is the same everywhere, but the section conventions differ by market and by design code, so check the comparison against the code you are designing to.
- 04
If you are pricing a project and need cost drivers
Machine price is driven by four things: station count from the profile, drive power from the material, speed and automation from your output target, and auxiliary equipment from how your coil arrives. Read those four before comparing any two quotations — a cheaper quote is usually a smaller specification, not a better deal.

About the Knowledge Base
Where should I start if I am new to roll forming?
With what the process is and what a production line actually contains — decoiler, leveling, forming, cutting, stacking. Buyers who skip this step tend to specify a forming machine when what they need is a line, and then discover the missing front end after the order. The introduction article takes about ten minutes and prevents that.
Is any of this specific to your machines, or is it general reference?
Most of it is general — the process, the profile conventions and the standards apply to any roll forming line, which is why the articles are written to be useful even if you buy elsewhere. What is specific to us is the machine specifications and the configuration advice, and those sit on the machine pages rather than here.
How current is the material?
The technical content reflects current practice and standard designations. Where a figure depends on your material or your market we say so rather than giving a single number, because the honest answer often depends on the section and the design code. If you are working to a specific standard, check it against that standard directly.
Do you cover the standards in my market?
We cover the common designations and the equivalences between them — Japanese, ASTM, European and Chinese conventions for coated steel, for example. Where a local designation has no exact equivalent we say that rather than implying a false match. If your market has a code we have not covered, ask and we will tell you what applies.
Can I get help applying this to my own product?
Yes. Send the section drawing or a sample cut-length with the material and thickness, and we will tell you which machine type applies and what the station count implies. That is the same starting point we use for a quotation, so it costs you nothing to ask before you commit to a specification.
