Metal Folding Machines: Folding vs Roll Forming
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.
Metal Embossing Machines: Types, Applications and Selection
What a metal embossing machine is, how dual-roll coil lines differ from stand-alone heads and roof mills, where patterned sheet is used, and how to specify thickness, width and exit.
Barrel Corrugated Roof Sheet Machines
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.
Double Head / Dual Side Decoilers Explained
What a dual-head decoiler is: two mandrels on one base with a rotate index. How that differs from two independent decoilers on a sandwich line. Per-side tonnage stays per-side.
Hat Purlin Machines: Profiles, Applications and Selection
Hat, omega, furring and solar-strut lines are different machines that share a hat-shaped section. Structural hat/sigma purlin duty is not a light-gauge furring mill. Named builds stay labeled.
Sigma Purlin Roll Forming Machines Explained
A sigma (Σ) channel is not a C, Z, or hat. Flower design uses more bend lines in the web. Station-count bands from tooling wiki are guidelines, not a named mill quotation.
I Purlin vs C/Z Purlin Machines
Search traffic for I purlin usually wants either a hot-rolled I-beam or a cold-formed C/Z. They are different equipment classes. Named C, Z, CZ and CUZ builds stay on their own pages.
Hydraulic Purlin Machines: Features and Benefits
Hydraulic on a purlin line is usually three systems: mandrel expand, pre-punch, and cut. They are not the main mill drive. Named C, CZ and CUZ packs keep punch kW and host kW apart.
Standing Seam Lock Roof Machines
A lock roof is a panel mill plus, on mechanical seam, a seamer and clips. Snap-lock and mechanical lock are different packages. KR18, slide, and the 0.8–1.2 mm wiki host each keep their own ratings.
Gutter Elbow Machines
A gutter elbow search usually wants a downpipe pipe-bender (~2.2 kW, ~90°), not the eaves-trough mill. Necking/reducer pair is a third quotation. The 2.2 kW figure is the bender, not the mill main motor.
