Length
3 m is often cut length
Set the encoder on the roof mill. Coverage width stays on the drawing.

Wide-Format Roofing Production Solution
Buyers type “3 m roofing” for four different jobs: a 3 m cut length on a roof mill, a 3 m (or longer) folding brake, a wide shear, or a 3 m outfeed table. Coverage width still follows the panel drawing — typically well under 3 m. The example below is the long CNC folder used for flashings.
Who it's for
Roof shops that cut long sheets, fold long flashings, or need a wide shear / table — and buyers who thought “3 m” meant a 3 m-wide roll former.
Fold
Long flashing is a folder
The 8 m CNC class folds custom gutters and flashings in seconds per piece.
Shear
Wide shear is a cut-off
A 4×4000 swing shear lists 4.1 m width on that quotation — sheet processing, not a roof mill.
How to choose a line
- Roof panels 3 m long (or other cut length) -> roof mill; length is an HMI setpoint. Coverage follows the profile drawing
- Long custom flashing / gutter fold -> CNC folder (example below; 8 m class)
- Wide blank cut before forming -> swing shear 4×4000 class (7.5 kW; SS ≤2 / CS ≤4 mm; width 4.1 m) on the sheet-processing solution
- 3 m outfeed / packing table -> table as a line item on the mill quotation
- Standing seam, sandwich, or 1220 mm sandwich width -> those solutions; sandwich feed 1220 mm is not “3 m wide roofing”

What's included
Length vs width vs fold vs shear, one 8 m folder example, roof-mill cut length and wide shear as matching rows, and a quote checklist.
What to send for a quote
- Whether 3 m is cut length, fold length, shear width, or table length
- Panel drawing (coverage and rib) if you need a mill
- Flashing drawing and steel thickness if you need a folder
- Max piece length you will run in year one
- Site voltage / frequency
- Whether a wide shear is infeed to a mill or a stand-alone blanking machine
- If you need a 3 m-wide formed panel: send that drawing. That coverage is a custom mill conversation on this page.
Check before you quote
Width
Coverage is the drawing
A 3 m-long sheet still has the mill’s coverage width, not a 3 m-wide roll set.
Folder
Folder cycle is seconds
~12 s is a piece cycle. Roof mill speed is m/min on the mill quotation.
Shear
4.1 m is a shear file
The 4×4000 swing shear is sheet processing, not a roof-profile mill.
FAQ
Do you sell a 3 m-wide roofing mill as a stock model?
This page treats 3 m as length, fold, shear or table. A formed panel whose coverage is 3 m wide is a custom drawing conversation.
Can the 8 m folder replace a roof mill?
The folder makes long flashings. Repeating roof profiles run on a roll former. Year-one mix decides which quotation opens first.
How are price and lead time quoted?
Send the quote checklist. Commercial terms come back on the offer.
