TAIBANG / EQUIPMENT
Form C, Z, U and Sigma structural purlins. Start with section sizes, thickness range and hole pattern.

APPLICATION & EQUIPMENT
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.
YOUR SPECIFICATION BRIEF
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
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 | Voltage, controls language, guarding and any destination electrical code are matched in the project offer. This page does not publish a fixed cabinet brand or a certified compliance mark. |
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.
* Engineering discussion range / workshop baseline; confirmed per signed project. Photographs and video on this page are reviewed workshop views of other forming equipment, not a catalog shot of this exact purlin model.
FROM BRIEF TO ACCEPTANCE
Confirm section family and size range
Review coil grade and thickness band
Map punching and cutting sequence
Agree changeover method
Measure trial members against the drawing
WORKSHOP VIEWS / PROJECT DISCUSSION
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
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.
Plan your machine inspection ↗Record trial material, sample measurements, the operating cycle and the documents needed for acceptance.
Inspection planning ↗BEFORE YOU REQUEST A QUOTE
Yes. Describe your intended panel or sheet in text. Contact info@tbrollforming.com to discuss sharing a sketch or reference image; this form does not upload files. Final tooling and pricing need an agreed technical brief.
Discuss the material, product geometry, length mix and full operating cycle. Forming speed alone does not describe finished output per shift.
Ask for a written offer that defines the equipment list, optional items, inspection, delivery terms, installation responsibilities and support scope.
Your next production line
Send your drawing, material, finished output target and destination. Build the equipment, inspection and delivery scope into one project brief.
