Metal Sheet Processing Solution
Blanking and cut-off around a roll former is a shear class: flying (tracking) shear, swing shear, or leveller-plus-shear. Folding long flashings is a folder. Melt, hot strip and CGL are steel-mill equipment. The example below is a flying shear on a delivered order.
Who it's for
Roll-forming plants that cut on the fly, blank wide sheet, or level then shear — and shops that fold flashings. Integrated steelworks searches go to mill OEMs.
Wide blank
Swing shear is a width machine
4×4000 class: 7.5 kW, SS ≤2 / CS ≤4 mm, 4.1 m width.
Level
15-roll pairs with 30 T
45 kW leveller, 3–6 × 2000, 415 V / 50 Hz. The cone-head on that quotation is 30 T; the 10 t hydraulic decoiler is a different infeed package.
How to choose a line
- Cut-to-length on a moving strip, mill speed class 25–30 m/min -> flying shear (example below)
- Wide blank, stop or swing cut -> 4×4000 swing shear (7.5 kW; SS ≤2 / CS ≤4; width 4.1 m)
- Level then shear medium plate -> 15-roll Ø115, 45 kW, 3–6 × 2000, 415 V / 50 Hz, with 30 T cone-head decoiler
- Heavy CTL 5 × 1600 -> 25 T dual-head, 132 kW DC leveller, ≤50 m/min on that quotation
- Long flashing / custom gutter fold -> 8 m CNC folder (wide-format / rainwater solutions)
- Melt shop, hot strip, galvanizing pot (CGL) -> steel-mill OEM. Coating language on formed GI follows EN 10346 on the coil you buy
- Profile forming (roof, purlin, fence) -> the matching product solution; this page is cut / level / fold around the mill

What's included
Shear-class choice, one flying-shear example, swing / 15-roll / heavy CTL and folder as matching rows, steel mill routed out, and a quote checklist.
What to send for a quote
- Flying vs swing vs leveller+shear vs folder
- Strip width, thickness, yield (SS vs CS on the swing-shear file)
- Line speed of the mill the shear must follow
- Decoiler class (30 T with the 15-roll file; 25 T dual-head with 5×1600)
- Site voltage (example flying shear 220 V / 60 Hz; 15-roll 415 V / 50 Hz)
- Whether cut is on the mill or a stand-alone CTL
- If the search is steel manufacturing / CGL: send melt and pot questions to that mill OEM
Check before you quote
Pairing
15-roll with 30 T
That leveller quotation lists a 30 T cone-head. The 10 t hydraulic decoiler is a different infeed package.
kW
3.8, 7.5, 45 and 132 stay apart
Flying servo, swing shear, 15-roll and heavy DC leveller are four files.
Mill
CGL is a steelworks line
Galvanizing-pot questions belong to mill OEMs. Formed GI coating follows the coil standard you buy.
FAQ
Is a shearing machine the same as a folding machine?
Shears cut length or blanks. Folders bend long flashings. Flying, swing and leveller+shear are three cut classes.
Do you quote a steel manufacturing mill here?
This page quotes cut, level and fold around roll forming. Melt, hot strip and CGL go to steel-mill OEMs.
