Believe Industry Company have below machines for different requirements of purlins
All abover machines have various design for specific demands.
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.
Governing Factor: The calculator automatically compares strength versus stiffness. Usually, for longer spans (e.g., > 6m), deflection (sagging) is the limiting factor rather than the steel actually breaking.
Section Properties: The tool uses simplified Moment of Inertia (I) and Section Modulus (S) values for common C/Z sizes. For a professional website, these values can be updated to match your specific roll-formed profile geometry.
Units:
Span: Input in meters.
Load Output: kN/m (kiloNewtons per linear meter). To convert to kg/m, multiply the result by approximately 101.97.
Assumptions: This model assumes a “Simple Span” (purlin supported at both ends but not continuous). For Z-purlins that are lapped, the load capacity can increase by up to 30-50% due to continuity over the rafters.
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.
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.
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.
A C and Z Purlin Roll Forming Machine requires precise hole punching. Beli RollForming offers 3 core methods to achieve this:
Independent Servo Feeder and Punch Device: The fastest solution for high-volume production and complex hole patterns, utilizing a separate system before forming.
Pre-cutting Device: Integrated punching before forming, often used for simple flange holes, offering a cost-effective setup.
Post Punch Device: Punching is done after the profile is fully formed. This provides maximum flexibility for switching between different C and Z profiles and sizes.
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.
