C & Z Purlin Roll Forming Machine - Standard Model

Structural purlins need straight, twist-free sections because every bend error multiplies across a roof bay. This C & Z 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 C & Z Purlin Roll Forming Machine is a fully automatic roll forming line designed to produce C and Z purlin profiles for light steel structures. With Roller stations :20 rows forming stations, 1-3mm( 15-9 gauge ) material, feeding width max 500mm, 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 ISO 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 C & Z Purlin

The profile is formed progressively through Roller stations :20 rows, which spreads the bending load over many passes and keeps section dimensions steady across long runs. The line is set up for coil in the 1-3mm( 15-9 gauge ) thickness range, with roller clearances and cutting capacity matched to that material program. Feeding width is max 500mm, which determines the widest profile this machine can produce and the coil sizes you can buy economically. Electrical supply is 380v/50hz/3p (As Requested), 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 High grade 45# forged steel, giving predictable profile accuracy and long intervals between re-grinds.

Key Features

Roller stations :20 rows forming stations for stable, precise profile shaping
Processes PPGI,PPGL raw material
Handles 1-3mm( 15-9 gauge ) material thickness
Feeding width up to max 500mm
PLC(imported Brand) for automatic operation
Machinery test report and video outgoing-inspection provided
CE ISO 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 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.

How many forming stations does this machine have?

This model is equipped with Roller stations :20 rows. The station count is matched to the profile complexity, so each pass adds only a small bend and the section holds its shape without spring-back issues.

What material thickness can this machine process?

The machine is configured for coil thickness in the 1-3mm( 15-9 gauge ) range. If you plan to run material outside this range, tell us in advance so we can adjust the roller stations and cutting unit.

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.

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.
