3-Meter Roofing Machines

1. Which 3 m you are buying

3m roofing is not a profile family. Buyers mean a 3 m folding/brake package for roof flashings, a 3 m guillotine, outfeed tables 3 m long, or panels cut at 3 m. A roof roll former is specified by profile, thickness, and stands — 780 glazed tile and dual-layer 20+22 are mill classes. “3 m” is a length.

2. 3 m brake and 3 m shear

Process library: 3 m hydraulic press brake, PPGI/GI ≤2 mm, bend length ≤3 m, red finish, unpacked. Companion 3 m hydraulic shear is a separate process. That pair makes flashings and blanks. It does not roll trapezoid ribs.

8 m CNC folder is a longer cousin (~8000 mm, ~1.5 mm steel). 4.1 m guillotine (4×4000) is a blank shear at 7.5 kW. Those are not 3 m roofing mills.

3. 3 m tables on forming lines

Many process sheets dump onto 3 m tables ×2 (corrugated/arc, CUZ, KR18 runout, small hat, Euro fence, villa 2×3 m). That is outfeed furniture. The mill speed is still that host’s m/min. Dual-layer tile in this catalogue uses an 8 m dual stacker; floor-deck companion uses 8 m or 12 m auto stack. Those are not 3 m machines.

4. Cut length vs mill class

Double-layer wiki quotes cut tolerance about ±1 mm / 3 m on the standard configuration. That is a length accuracy statement, not a “3 m roofing machine” quotation. Standing-seam and barrel sheets run 6 m lengths on some orders. Ask for the panel length recipe on the HMI, not a 3 m mill nameplate.

5. Buyer FAQ

We need a 3 m roofing machine for trapezoid sheets.

You need a trapezoid (or dual-layer) roll former plus tables or a stacker long enough for 3 m panels. The 3 m brake will not roll the ribs.

Is 3 m the coil width?

Unlikely. Roof feeds in this catalogue are 1000–1250 mm class, not 3 m wide strip.

Can the 3 m brake fold K-style gutters?

Within ≤2 mm and ≤3 m, as a blank folder. Volume K-style is the rain mill.
