Z purlin roll forming machine works in the same principle as a c purlin roll forming machine does when the purlins are used in metal building systems, only the purlins’ shapes make difference.

Z steel purlins can be used for a variety of applications, but 90% for steel structural building system, and 10% for other usages (some people use z steel purlins as the supporting clip inside sandwich panels, while some others put z steel purlins on a samples racks etc). Different applications of Z purlins decides different specifications or configurations on a z purlin roll forming machine.

Brief Introduction of Z steel purlin roll forming machine:

As steel purlins for steel structural building, Zed shaped section channels as well as Cee shaped section channels (more at c purlin roll forming machine) always come to the mind of architects. There are different situations about which ones to choose, Cee steel purlins or Zed steel purlins (we will have an articles describing the difference between C purlins and Z purlins later), but a z shaped steel channel roll forming machine will never be absent from the purchasing list.

We have designed traditional z shaped section channel roll forming machine for the production of z steel purlins, and also a light-gauge z purlin roll forming machine was built before for the production of z shaped rack tables. A traditional z purlin roll forming machine always produces punching holes or slots on both the Z purlin webs and flanges, while a light-gauge z purlins have only holes on z channels flanges, and some light-gauge z purlins z purlins have only holes on z channel webs. Both light gagues and high gauge z steel purlins are usually made out of hot-dip galvanized steel or cold rolled steel.

Like c purlin roll forming machine, z steel purlin roll formers also is designed to produce the section channels of different sizes, but the change to make a different size z purlin is manual. Clients need to manually change the spacers installed between the rolling tools, and manually change cutting dies as well. Nowadays there are c/z purlin roll forming machines which automatic change the sizes of C steel purlins or Z steel purlins quickly (more at interchangeable c/z purlin rol forming macine), it could save more production because it takes only 10 minutes at most to change for production of z steel purlin with a different size. Z steel section channel roll forming machine usually consists of a manual decoiler, feeding guide with leveling device, hydraulic punching tools, roll forming part, hydraulic cutting, transmission system, a PLC control cabinet, a hydraulic oil pump and runout tables.
