4 Inch Zee Purlin Roll Forming Machine - US Style Line

Structural purlins need straight, twist-free sections because every bend error multiplies across a roof bay. This 4 Inch Zee 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 4 Inch Zee Purlin Machine is a fully automatic roll forming line designed to produce 4 inch zee purlins for US style framing. 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 ISO CE 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 4 Inch Zee 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
ISO CE 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 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.

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.

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.

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.

Zee Purlin Roll Forming Machine FAQ

What is a zee purlin roll forming machine?

A zee purlin roll forming machine is a cold forming production line that turns galvanized steel coil into Z-shaped (zee) purlins in one continuous process. This 4 inch US style zee purlin machine is engineered for the American market profile standard, running pre-punched or plain strip through a precision roller station sequence, then cutting to length on the fly.

What profiles can a purlin zee roll forming machine produce?

Depending on the roller sets installed, a purlin zee roll forming machine can run different zee depths, lip heights and steel thicknesses. The same machine frame can be re-tooled to change profile dimensions, which makes it flexible for structural steel fabricators and building material traders.
