An Automatic Transverse CZ-Type Steel Roll Forming Machine refers to a roll forming line designed to manufacture C-purlins and Z-purlins (or similar channel shapes) with features that allow automatic/quick size changes, profile type interchange (C ↔ Z), punching/cutting, etc.
This machine processes flat strip metal (steel, galvanized steel, etc.) and produces structural channel profiles (“C” and “Z”). Key functions:
1.Decoiling: Unwinding coil of steel.
2.Leveling / Straightening: Remove curvature or coil set so the strip is flat before forming.
3.Feeding & Guiding: To properly align the strip into the roll forming stations.
4.Roll Forming: Series of rollers gradually bend the strip into the desired web, flange, lip to make “C” or “Z” shapes.
5.Punching / Perforation: Make holes, slots in web or flanges (for bolts, fasteners) either before or after forming.
6.Cutting / Shearing (Transverse Cut): Cut the formed profile to length. Could be a hydraulic shear, flying shear, or similar.
7.Automatic Profile Interchange / Size Change: Ability to switch between different profile sizes or types (C vs Z) quickly with little or no manual adjustment. Might involve adjustable rollers, cassette systems, etc.
8.Control System: PLC/HMI to set parameters (length, count, punching positions), monitor operations, automate adjustments.
9. Output / Table / Stacking: For collection of cut pieces, stacking or packaging.
From real examples, here are what automatic transverse CZ-type roll forming machines tend to offer. These give you a sense of what “good” looks like.
Parameter | Typical Values / Range |
Material thickness | ~1.0 mm up to around 4.5 mm depending on structural requirements. E.g. one FX450 model handles up to 4.5 mm thickness. |
Web / flange / lip size / profile range | Web widths (C-profile) from ~80–350 mm,Z from ~120–350 mm in many machines. |
Forming Speed | Often in the range of ~ 15–35 m/min (depending on thickness,punching/cutting actions). Without punching/cutting,speed might be higher. |
Roller / Shaft materials &steps | Hardened steel rollers (e.g. Cr-12,GCr15),shafts often 40Cr with quenching &tempering. Number of roller stands (steps) ~15-26 or more in fully automatic/high speed machines. |
Cutting &Punching | Hydraulic punching,pre- or post-forming;hydraulic or servo-controlled cutting. Transverse cut (“shear”) to length. Some flying cut (non-stop cutting) in high speed models. |
Profile Interchange / Size Change | Automatic or quick interchange between C &Z profiles;some machines can change widths,lip/flange sizes via PLC or servo,or cassette type modules;changeover time in some models ~5–15 minutes for typical size changes. |
Power / Drive System | Drive by gearboxes or chains;main motors power the forming,auxiliary motors for cutting/punching. Example:22-30 kW motors common in 1.0-3.0 mm machines. |
Tolerance / Accuracy | Cutting &punching positional tolerances typically a few mm (e.g.,+/-1-3mm) depending on machine. |
The Automatic Transverse CZ Type Steel Roll Forming Machine has a wide range of industrial and construction applications, mainly related to steel structure fabrication. Below is a detailed explanation of its applications, industries served, and the benefits it provides in each.
A. Steel Structure Buildings
Used to produce C and Z purlins, which are the main structural members in steel frame buildings.
These purlins act as horizontal supports for roof panels and wall claddings.
Widely used in:
Factories
Warehouses
Workshops
Industrial sheds
Logistics centers
B. Solar Panel Mounting Systems (Photovoltaic Structures)
CZ purlins serve as support beams or mounting rails in solar photovoltaic (PV) structures.
Their strength-to-weight ratio and ease of installation make them ideal for solar farm frameworks and roof-mounted solar supports.
C. Prefabricated & Modular Buildings
Used for lightweight steel frameworks in modular homes, portable cabins, and prefab offices.
The machine’s automated size adjustment helps produce custom-length purlins efficiently for modular assembly.
D. Infrastructure & Public Projects
C/Z sections produced are used in:
Highway guardrails
Bridges and sheds
Airport terminals
Bus stations
Railway stations
E. Industrial Shelving and Racking Systems
Roll-formed CZ sections are also applied in storage racks, shelving, and logistics equipment due to their high load-bearing capacity.
