Multi Function Sigma M Purlin Machine - U & C Profiles

Structural purlins need straight, twist-free sections because every bend error multiplies across a roof bay. This Multi Function Sigma M 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 Multi Function Sigma M Purlin Machine is a fully automatic roll forming line designed to produce sigma M purlins plus U and C profiles on one line. With 20 forming stations, forming speed 10-15 m/min, 1.9-2.6 mm material, 18.5 kW 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. 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 Multi Function Sigma M Purlin

The profile is formed progressively through 20, which spreads the bending load over many passes and keeps section dimensions steady across long runs. Rated forming speed is 10-15 m/min, which sets the practical daily output of the line and makes production planning straightforward for the sizes you run. The line is set up for coil in the 1.9-2.6 mm thickness range, with roller clearances and cutting capacity matched to that material program. The main drive is rated at 18.5 kW, sized for continuous operation at full line speed without overheating on long shifts. Electrical supply is 380 V, and the control cabinet can be adapted to your local voltage when ordering. The forming shafts are 74mm, selected for stiffness so the roller stack stays aligned under load.

Key Features

20 forming stations for stable, precise profile shaping
Forming speed 10-15 m/min for high productivity
Processes Galvanized Steel Coil raw material
Handles 1.9-2.6 mm material thickness
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 Galvanized Steel Coil 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 20. 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 is the forming speed of this machine?

The rated forming speed is 10-15 m/min. Actual output depends on the profile, material gauge and cutting cycle; we confirm the tested speed for your configuration in the quotation.

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.
