C Z  Purlin Roll Forming Machine

What’s C and Z Purlin?

In steel construction, the term purlin commonly refers to roof structure members that span parallel to the building ridge , and support the roof sheets, wall panels .. The purlins are in turn supported by beams or walls. Purlins are most commonly used in Steel Building Systems, where C -Shapes or Z-shapes are used in a manner that allows flexural continuity between spans. BELI® C Z Purlin Roll forming Machine can form different sizes of C-shape U-shape, Z-shape purlins.

How to change the machine to produce different sizes of C or Z purlin?

Channel or Purlin sections, with or without flange, are usually referenced as C shapes; Channel sections without flange stiffeners are also referenced as U shapes; Point symmetric sections that are shaped similar to the letter C are referenced as C shapes. Section designations can be customized and even specific to a manufacturer. In steel building construction industry, secondary members such as purlins (roof) and girts (wall) are frequently cold-formed steel C, Z or U sections,

C Z Purlin Roll Forming Machine always adopt duplex roll forming mills. It is very easy to change the dimension of the product; for example, the web height (“H”) or the leg length (“L”) of “C” Purlins. If both dimensions have to be changed web height and leg length, marked “H” and “L” respectively then two independently adjustable duplex mills can be combined, using a common drive. Changing the width in the first mill will change the leg length “L”, and changing the second mill will change the web height “H”. BELI® C Z Purlin Roll Forming Machine can form 80-350 mm width C and Z Shape Purlins. and thickness can be up to 5mm.

c and z purlin size and holes design

The two mills have one common centerline. The third dimension, the lip width , can also be changed by adjusting the strip width that enters into the first mill. Or by having a third duplex mill incorporated into the unit . Our C and Z Purlin Roll Forming Machine can produce both C and U Purlin without any change of the rollers. The entry guides and the straighteners are attached to the mill stands. Therefore changing the product dimensions is very simple and quick. Some of these mills are equipped with servo motors and PLC controllers or computers.

Punching holes device on C&Z Purlin Machine

The whole line is containing prepunching or post punch and cutting presses can produce infinite kinds of “C” channels (studs) and “U” channels (tracks) within the parameter of the machine without tool change. Frequently, the only requirement is to enter the part number (or dimensions)and the required quantities into the PLC or Computer system by Touch Screen . The product dimension changeover time can be as low as 1 to 2 min.

How to adjust C Z Purlin Roll Forming Machine

Another quick-change “C” and “Z” purlin mill is forming one edge of the product up. At the other edge no need adjust, the top and bottom rolls can be easily exchanged by either rotating each stand 180º around a shaft or deflecting one leg up for the C Purlin or down for the Z Purlin . These designs enable the production of “C” and “Z” Purlins on the same machine without tool change.
