Sigma Purlin Forming Line
Sigma channel is quoted from your drawing. Flower-design guidance is about 18–22 stations and 1.0–2.5 mm. C80-300 ~15 kW and CZ servo 42 kW stay on those C/Z hosts.
What this process looks like
A sigma channel has extra web folds. This catalogue does not lock a mill kilowatt, decoiler mass or cut package for that letter. We quote from your PDF.

Every web fold, lips and millimetres. If it is a flat-web C, retag and use the C host.

Hole map next: pre-punch in the strip versus after form. C/Z punch-in-flat is documented on those families only.

Stop hydraulic versus flying. Purlin shear variants live on C/Z/U sheets until the sigma proposal copies one.

Web folds in the right order, twist, hole pitch if punched. Speed claims wait until that board matches.
What's included
This line
This page: How to RFQ a sigma flower: drawing, coil, holes, cut. Station-band guidance only.
Standard build
Sister lines: C/Z interchangeable, CUZ (C/U/Z + ellipse), and solar strut if the PDF is actually a hat.
Key details
Note 1
The PDF is actually sigma — A Cee with an extra fold callout still needs the extra flower, not an HMI rename.
Hole family on the proposal
Racking uprights often share a different pitch than roof purlins.
kW from this quote
C80-300 ~15 kW and CZ 42 kW are other machines.
FAQ
Is there a standard sigma mill kilowatt in this catalogue?
Not on a named specification. About 18–22 stations and 1.0–2.5 mm is flower-design guidance. Motor size waits for your drawing.
Can a CZ auto-changeover mill run sigma?
That host stores C and Z recipes. A sigma web fold is a different flower. Send the PDF rather than renaming the HMI.
How are price and lead time quoted?
Send the dimensioned sigma drawing, thickness and hole map. Commercial terms come back on the offer.
