CZ Purlin Machine - PLC Motor Control

Structural purlins need straight, twist-free sections because every bend error multiplies across a roof bay. This CZ Purlin forms the target purlin sections with driven stations sized to the material thickness you run, then straightens and cuts to length automatically, so the purlins you supply go up on site without forcing or re-drilling.

Overview

The CZ Purlin Machine is a fully automatic roll forming line designed to produce CZ purlins with PLC motor control. With 21KW 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/ISO9001 certified with a 2 years warranty. Every unit ships with a machinery test report and video outgoing-inspection.

Heavy-duty versions run thicker coil for main structural members, while lighter sections feed secondary framing. We help you match the forming station count and punching options to the section range you plan to sell, so you do not pay for capacity you will not use in the first two years.

Key Specifications of the CZ Purlin

The main drive is rated at 21KW, sized for continuous operation at full line speed without overheating on long shifts. Electrical supply is 220V-3P-50HZ 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 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/ISO9001 certified

Programmable punching is available as an option: bolt holes for end plates and bracing are punched during forming, so your customer assembles the frame faster on site and you can charge a premium for a ready-to-erect product instead of raw lengths.

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 21KW. 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 220V-3P-50HZ 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.

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.

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.
