CZ Purlin Roll Forming Machine – C/Z/U/Sigma Structural Line (C80-300)
Custom C, Z, U and Sigma structural purlin roll forming lines (1.5-3.0 mm Q235/Q355 coil, C80-C300 & Z120-Z300 web sizes). Multi-station hydraulic punching, width changeover & 7-step FAT protocol.
APPLICATION & EQUIPMENT
Define the product you need to sell.
Structural purlin equipment is discussed from the finished member, not from a brochure model number. Share the C, Z, U or Sigma section family, web and flange sizes, thickness range, and whether width changeover must be manual, motorized or servo-assisted. Hole patterns, lip geometry and cut lengths belong in the same brief. This page uses reviewed workshop photographs of coil-handling equipment and a factory-hall forming line; those views show general shop arrangements, not a named purlin model.
Typical applications
- Roof purlins and wall girts
- C, Z, U and Sigma structural members
- Primary and secondary steel framing workshops
Decisions to make early
- List every section that must run on the same equipment.
- Treat punching pitch as part of the product, not an accessory.
- State how often the line must change width during a shift.
YOUR SPECIFICATION BRIEF
Five inputs for a useful quotation.
Share the details you have. If a dimension or requirement is undecided, describe the intended finished product.
| Project item | What to include |
|---|---|
| Section family | C, Z, U and/or Sigma; web, flange and lip dimensions; size range that must share one line. |
| Coil specification | Steel grade, coating, thickness range and strip width for the heaviest and lightest members. |
| Hole pattern | Web and flange holes, slots, pitch, edge margins and measurement points. |
| Changeover | Manual spacer, motorized screw or servo width changeover; expected size mix per shift. |
| Workshop | Coil mass, floor space, power supply and discharge / stacking method. |
Speed, power, tooling, tolerances and control components belong in the agreed machine specification. They are not fixed across this equipment category.
ENGINEERING REFERENCE PARAMETERS
Engineering discussion ranges — confirmed per project
The following engineering baseline reflects measured workshop machine parameters and tooling standards. These figures are category references, not a fixed machine specification.
| Engineering Subsystem | Design Range & Workshop Baseline |
|---|---|
| Section Discussion Range | C, Z, U and Sigma structural members. Engineering discussion range often starts around C80 to C300 and Z120 to Z300 web sizes; the shared size family is confirmed per signed project. |
| Material & Thickness Baseline | Workshop baseline discussion commonly covers commercial and high-yield structural coil in a thickness band around 1.5 to 3.0 mm. Heavier strip, higher yield grades and coating systems are confirmed per signed project, not from this page. |
| Changeover & Tooling Layout | Width and flange changeover may be discussed as manual spacers, motorized lead screws or servo adjustment. Stand count, shaft diameter and roll material are sized from the heaviest section and the required changeover method. |
| Punching & Cutoff Sequence | Web and flange holes may be pre-punched on flat strip or punched in line. Cutoff may be a universal post-shear or a profiled blade set. Sequence, station count and measurement points are workshop baseline topics until the drawing is agreed. |
| Line Speed Discussion Range | Forming and punching cycle discussion often sits in a range of about 8 to 20 meters per minute depending on thickness, hole density and cut length. Finished members per shift must include punching dwell, changeover and stacking time. |
| Electrical & Destination Requirements | Drive motors carry CE attestation (Certificate M.2023.206.C82549) under EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU, verified by UDEM International through March 2028. Voltage, controls language, guarding and any destination electrical code are matched in the project offer. |
SPECIFICATION BOUNDARY
Specifications on this page are either verified brochure baselines or engineering discussion ranges. Final line layout, drive sizing, roll-stand count, tooling material, tolerances and acceptance criteria are confirmed in your signed project offer — they are not fixed by this page. Workshop photos and video show general shop arrangements and mechanical motion; they are not images of a named, quoted machine model.

WORKSHOP VIEWS / PROJECT DISCUSSION
Look at the details. Define your requirements.
Supplied workshop photos are reviewed shop views of coil-handling equipment and a factory-hall forming line. They are not photographs of a named C/Z/U/Sigma purlin model. Use them to discuss layout only. Confirm section family, changeover method and acceptance measurements in the project offer.
WORKSHOP VERIFICATION / CUTOFF AND DISCHARGE

FACTORY VERIFICATION
Workshop trial footage.
Reviewed workshop footage of profile cutoff and discharge on forming equipment in the shop. It illustrates mechanical motion, not a named C/Z purlin model or a measured output rate.
Silent workshop footage; it shows mechanical motion, not a quoted machine's output.

Common buying questions.
What is the size adjustment range and changeover method between C and Z purlins?
The line handles web widths from C80 to C300 and Z120 to Z300 with 40 to 80 mm flanges. Motorized or servo-driven stepless sizing adjusts dimensions via HMI touchscreen commands, while 180-degree rotating roller cassettes enable C-to-Z profile transitions without manual tooling disassembly. Operational changeover duration depends on section size differences and operator routine, verified during factory acceptance trials.
How does the machine handle purlin web and flange hole punching?
The line integrates multi-station hydraulic punching units with independent cylinders for web slots and flange holes. The PLC controls hole positions and center-to-center distances along the purlin length according to steel building connection drawings.
What steel thickness and yield strength can this purlin line form?
Standard structural framing tooling processes galvanized and structural steel strip from 1.5 mm up to 3.0 mm thickness (Q235, Q355, ASTM A653 Gr50). Heavier gauges up to 3.5 mm or higher-tensile coil require project-specific verification of shaft diameters, station counts, and motor sizing.
How is the machine packed and loaded into containers?
The machine body is protected with anti-rust oil, wrapped in waterproof film and shock-absorbent foam, and securely braced inside 20GP or 40HQ containers. Sensitive PLC control cabinets and hydraulic pump stations are packed in seaworthy wooden crates.
What is the typical lead time for this machine?
Typical fabrication lead time commonly ranges from 30 to 60 working days after receipt of the deposit and formal sign-off on tooling profile drawings. Multi-profile configurations or custom electrical specifications are scheduled per project agreement.
What after-sales support do you provide?
We provide technical assistance including remote video troubleshooting, rapid express delivery of spare parts, and on-site engineer dispatch for commissioning or repairs where agreed in the project contract.
What spare parts are included with the machine?
Each line ships with a standard wearable parts kit including limit switches, relay fuses, hydraulic seals, and adjusting tools. Custom spare packages including profile shear blades and punch die inserts are quoted per project requirements.
Can you customize the voltage for my country?
Yes, all drive motors and electrical cabinets are customized to match your local industrial grid, such as 380V, 415V, 440V, or 220V 3-phase at 50Hz or 60Hz. We configure industrial electrical components from recognized suppliers with proper thermal overloads to ensure stable operation.
Do you provide installation and commissioning service?
We provide comprehensive step-by-step video manuals and remote video technical support for machine setup and trial runs. On-site engineer dispatch for commissioning and operator training is available upon request and confirmed in the sales agreement.
What is the minimum order quantity?
Our minimum order quantity is 1 set. Whether you are starting a new fabrication workshop or adding a specialized line to an existing plant, we design, test, and ship complete custom roll forming lines with full technical documentation for single-machine orders.
What payment terms do you accept?
We accept T/T with a 30% advance deposit upon contract signing and 70% balance payment after factory trial acceptance and prior to sea shipment. Irrevocable letters of credit (L/C at sight) are also accepted upon mutual financial agreement.
