Sigma Purlin M Purlin Roll Forming Machine - Fully Automatic

Purlin lines are the backbone of steel-frame workshops: they convert coil into C, Z or sigma sections that carry roof and wall sheeting. This Sigma Purlin M Purlin is configured for the target section range and is delivered with the tooling set matched to your section sizes and thickness program.

Overview

The Sigma Purlin M Purlin Roll Forming Machine is a fully automatic roll forming line designed to produce Sigma (M) purlin profiles for steel structure buildings. With 22kw drive power, it delivers consistent, high quality production for building and construction applications.

Manufactured by Zhongtuo (ZTRFM) in Botou, Hebei, China, this machine uses high grade 45# steel shafts and rollers. PLC control ensures automatic operation. It is CE BV STV ISO certified with a 2 years warranty. Every unit ships with a machinery test report and video outgoing-inspection.

C and Z purlins from this machine go into portal-frame sheds, mezzanine floors, carports, warehouses and solar mounting structures. Z sections are typically specified where laps are needed over long spans; C sections are preferred for simpler connections. Offering both sections makes a workshop a one-stop supplier for steel-frame builders.

Key Specifications of the Sigma Purlin M Purlin

The main drive is rated at 22kw, sized for continuous operation at full line speed without overheating on long shifts. Electrical supply is 380V or Customized, and the control cabinet can be adapted to your local voltage when ordering. Length presets, counting and profile programs run on the PLC(imported Brand), so operators switch between jobs from the panel without mechanical re-setup. Forming rollers are Cr12, giving predictable profile accuracy and long intervals between re-grinds. The forming shafts are 45# High Grade Steel, selected for stiffness so the roller stack stays aligned under load. The machine is built to run Cr 12 High Grade Steel coil, and the tooling path is set up for these coated or galvanized materials without surface marking.

CE BV STV ISO certified

A purlin machine earns trust through section consistency. This Sigma Purlin M Purlin holds flange width and depth tolerance across the full run because each forming pass is calibrated to the material yield strength, and the cutting system is synchronized with line speed so every piece is the programmed length within roughly one millimetre.

FAQ

What is the minimum order quantity?

The MOQ is 1 set.

What material does this machine process?

It processes Cr12 coil.

What is the warranty period?

A 2 years warranty applies, with machinery test report and video outgoing-inspection provided.

Can the machine be customized for my profile?

Yes. Roller sets and profiles can be customized to your drawings, and OEM/ODM service is available.

What is the installed power of this machine?

The line is rated at 22kw. Power consumption in practice is lower than the rated figure for most running profiles, since the drive only loads under material.

What voltage does the machine require?

The standard configuration runs on 380V or Customized. We can adapt the electrical cabinet to your local supply, so confirm your site voltage when ordering.

Can it punch holes automatically?

Yes. The optional hydraulic or servo punching unit is synchronized with the PLC and can be programmed for end plates, bracing holes or slots. Hole positions stay aligned with the cut because both use the same program.

Do you supply lines for solar mounting profiles?

Yes, we build purlin and strut lines for solar mounting frames, including strut channel sections such as 41x21 and heavier rails. Specify the section drawing and coating and we will confirm the configuration.

Does it run both C and Z sections?

The two-in-one design runs C and Z profiles on one line by changing the roller arrangement and program. If you need both sections, this configuration usually costs less than two separate machines.

What thickness range is supported?

Standard purlin lines typically run 1.5-3.0 mm; heavy-duty versions extend to 4-6 mm depending on the model. The frame, gearbox and cutting unit are sized to the thickness you plan to run, so confirm your maximum gauge when requesting a quotation.
