C Purlin Machine

C Section Production

C Purlin Roll Forming Machines for Steel Structures

We supply C purlin forming equipment for galvanized steel sections used in roof framing, wall supports and steel-building projects. Our range includes adjustable C purlin lines and machines for defined channel sizes. The right configuration depends on web, flange and lip dimensions, steel grade, sheet thickness, punching layout and the number of size changes per shift.

Profile Geometry

Web, Flange and Lip Dimensions Come First

A C section is defined by its web, two flanges and return lips. Two drawings with the same web dimension can require different roll settings if flange height, lip length or steel strength changes.

For a customized C purlin roll forming machine, we review the smallest and largest sections together rather than approving the line against a single drawing. The required profile range affects roller adjustment, edge forming, straightening and cutting clearance.

  • Web: overall section depth, including the dimensional range to be covered
  • Flange: top and bottom leg dimensions and squareness requirements
  • Lip: return-edge dimensions, bend radius and available adjustment
  • Steel: grade or yield strength, coating and minimum/maximum thickness

What to Mark on the Section Drawing

Use the same units for all dimensions. Identify the inside or outside dimension convention, bend radii, hole centers and the tolerances that matter for assembly.

For roof purlins and wall girts, include connection details for cleats, braces or other supports. These can determine where holes must be punched along the web or flange.

Documented Model Data

Compare the Published C-Section Specifications

The C100-300 structural channel line and the lighter C32.5×35.5-75 channel machine have different material and dimensional limits. Their specifications should not be treated as interchangeable.

Technical Item C100-300 Structural C Line C32.5×35.5-75 Channel Line

The figures above belong to the linked models only. Actual material limits, production speed, dimensions and tolerances must be confirmed for the ordered configuration.

Size Changeover

Make Size Adjustment Match Your Production Schedule

An adjustable C purlin line can change the web and flange settings without replacing every forming roller. The benefit is most noticeable where one factory produces many C sizes in shorter batches.

For a quotation, list every section produced during a normal week, not only the largest profile. Changeover frequency, the preferred adjustment method and the first-piece inspection requirement all affect the appropriate machine arrangement.

  • Control-based size adjustment for supported ranges
  • Alignment and lip forming after dimension changes
  • Repeatability checks after switching between two sizes
  • Clear distinction between C-only and C/Z interchange capability

Line Operations

Punching and Cut Length Must Match the Drawing

A line that forms the correct C section can still create assembly problems if bolt holes, cut positions or finished lengths do not match the steelwork schedule.

01

Hole Pattern

Confirm diameter, quantity, web or flange location, edge distance and spacing for each section size. Different projects may use different connection patterns.

02

Cutting Method

Pre-cut and post-cut arrangements affect tooling and line coordination. Specify the shortest and longest finished lengths and any restrictions at the cut end.

03

Real Output

Compare the complete cycle with punching, cutting and receiving included. A forming-speed figure measured without punching is not the finished-output rate.

Factory Test

Inspect the First Piece After Every Critical Adjustment

At factory acceptance, the important result is not only that the machine runs. The approved C sections need to be checked against the drawings, particularly after changing from the smallest to the largest scheduled size.

  • Measure web, flange, lip and finished section angles
  • Check straightness over the agreed sample length
  • Confirm the hole-to-end distance and hole spacing
  • Check cut length and the shape of cut edges
  • Review controls, protective devices and receiving arrangements

We can discuss a test sequence using representative coil material and your accepted drawing tolerances before the machine specification is finalized.

What We Need to Quote Your C Purlin Line

For steel-structure fabricators comparing C purlin machine manufacturers in China, a profile drawing and production schedule are more useful than a single target speed.

  • C section drawings or CAD files
  • Web, flange and lip range
  • Material grade and thickness
  • Hole positions and diameter
  • Length and tolerance needs
  • Batch size and changeover rate
  • Expected output per shift
  • Destination power supply
One C line or a C/Z interchangeable line?

If your factory regularly supplies both C and Z purlins, we should review an interchangeable system instead of assuming that a dedicated C machine will cover both profiles.

Questions from Steelwork Buyers

C Purlin Forming Machine FAQ

WDoes a 300 mm web capacity cover every C profile? +

No. Web width is only one limit. The flange, lip, steel grade, thickness and forming geometry must also fit the same machine configuration.

↔Can the web and flange be adjusted without changing rollers? +

An adjustable C purlin machine can change the supported dimensions through its adjustment system. The exact automatic functions and the permitted size combinations depend on the ordered model.

◎Can holes be punched before the C section is formed? +

Pre-punching can be part of the line arrangement. The required positions, hole sizes, spacing and relationship to the cut length must be included in the project drawings.

mIs the advertised forming speed the finished production speed? +

Not necessarily. For example, the published 25 m/min figure for the C100-300 line is specified without punching. Actual output depends on the ordered punching, cutting and receiving cycle.

∠Which dimensions should be checked at acceptance? +

Check web, flange, lip, angles, straightness, hole positions and cut length against the approved drawings. Test representative dimensions across the ordered range.

C/ZShould I choose a C-only or C/Z interchangeable line? +

Choose around your production mix. If most orders are C sections, a dedicated C line may suit the operation. If both C and Z sections are routine orders, compare the changeover requirements of an interchangeable line.
