Heavy Duty CZ Purlin Machine - PLC Gear Motor

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 Heavy Duty CZ 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 Heavy Duty CZ Purlin Machine is a fully automatic roll forming line designed to produce heavy duty CZ purlins with PLC gear motor. With 30Kw 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 Heavy Duty CZ Purlin

The main drive is rated at 30Kw, sized for continuous operation at full line speed without overheating on long shifts. Electrical supply is 480V 60Hz 3P, 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 PPGI PPGL GI GL coil, and the tooling path is set up for these coated or galvanized materials without surface marking.

Key Features

Processes PPGI PPGL GI GL raw material
PLC(imported Brand) for automatic operation
Machinery test report and video outgoing-inspection provided
CE BV STV ISO certified

A purlin machine earns trust through section consistency. This Heavy Duty CZ 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 PPGI PPGL GI GL 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 30Kw. 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 480V 60Hz 3P. We can adapt the electrical cabinet to your local supply, so confirm your site voltage when ordering.

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.

What section sizes can this machine form?

The machine is tooled for your section range, typically C and Z purlins from 80 mm to 350 mm web depth; heavy-duty versions handle thicker material up to 6 mm. Send your section drawings or size list and we confirm the forming stations and tooling.

How accurate is the cut length?

The cutting system is synchronized with the line encoder, and finished lengths are held to approximately plus or minus 1 mm. Longer programs run continuously with the PLC tracking the count.

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.
