Heavy-Duty CZ Purlin Machine for Steel Structure & Solar Mounting Production

This C75-300 / Z120-300 automatic CZ purlin roll forming machine is our star models of Beenew’s machines, they are designed for manufacturers who require stable performance, fast production speed, and reliable long-term operation when producing C and Z purlins, it is widely used in steel structure industry and solar mounting system industry.

This CZ purlin machine is suitable for continuous production of:

1.5-3.0mm Q355 / 345MPA carbon steel
1.5-2.5mm 550MPA high-strength steel

It is widely used for producing structural purlins and support profiles for steel structure buildings, warehouses, workshops, logistics centers, and photovoltaic solar mounting systems.

The CZ purlin roll forming machine matches with 30KW servo motor driving and small servo motor quick size change, customized online punching different holes, and universal cutting technology. So this CZ purlin forming machine combines C or Z purlin producing flexibility with high efficiency and durable producing for daily needs.

 

 

Stable Production for Thick & High-Strength Steel

Many standard metal purlin machines struggle when running thick material continuously. This model is specially built for heavy-duty production and stable long-hour operation.

This C75-300/Z120-300 steel purlin forming machine frame is made from H400 steel construction, combined with large-diameter shafts and gear/sprocket transmission, providing stronger driving force and smoother operation during forming.

 

Suitable for carbon steel coil as:

3.0mm Q355 steel
2.5mm 550MPA high tensile steel
PLC Control Automatic Size Change

 

Supports automatic size adjustment through the PLC touch screen system.

Operators can quickly change directly from the control panel without complicated manual adjustments.
(1) Web width
(2) Flange height
(3) Lip size
(4) Production length
(5) Hole vertical distance

Available Size Range

(1) C Purlin
Web Width: 75-300mm
Flange: 40-80mm
Lip: 12-25mm

(2)Z Purlin
Web Width: 120-300mm
Flange: 50-80mm
Lip: 12-25mm

For changing between C and Z profiles, the machine uses manual cassette exchange. Compared with complicated automatic switching systemsit is the most reliable structure and easier maintenance .
