Metal fencing is several mills: Euro picket, dual-fence overlap, square/special panel, W-beam. Voltages 50 Hz and 60 Hz on named builds stay labeled. Picket ratings on this page follow the named Euro paling mill.
A triple-layer roof mill is three profile stacks on one frame. Thickness, speed and power stay with that drawing. Dual-layer builds such as 18.5 kW HS40 keep their own two-deck ratings.
Barrel / horizontal-arc corrugated is a change-gear host with Ø500 rolls, not a K-span and not a roof-tile mill. Named: Al 2 mm / GI 1 mm, 22 kW ×2, 10–15 pcs/min. Embosser stays off this page.
Frame-making here is light-gauge steel: villa LGS, high-speed stud/track, U-stud. Not a hot I-beam mill. Named MF-2500T, 4+16 stud line, and U-stud hosts stay labeled.
Shear on a roll-forming line is stop-cut, flying/tracking, guillotine, pedal, or a leveling-shear cell. Named 3.8 kW flying, 4×4000 guillotine 7.5 kW, and 15-roll leveling-shear stay labeled.
A folder bends blanks. A roll former profiles coil continuously. 8 m CNC folder (~7.5/8 kW, ~125°) is not a roof mill. 3 m press brake ≤2 mm is a third crate.
Straightening on ZTRFM files is usually a station on a forming or CTL line, not a standalone bar straightener mill. U-stud, square-tube, special-section and heavy CTL each name their own straightener. A dedicated tube-straightener kW is not published here.
Roll formers run pre-galvanized or pre-painted coil. A continuous galvanizing line (zinc pot, CGL) is a steel mill, not a roll-forming accessory. Pot temperature and CGL line speed live on mill OEM sheets. Use EN 10346 coating mass language.
