Z Purlin Forming Machine

In construction, purlins are used in tall walls, large ridge beams and floor structuring. They are also used to bridge the gaps left in the construction process. Manufacturers produce purlins with the help of cold roll forming machine. Cold form steel is formed or bent in a or forming machine, which in turn makes Cee and Zee sections out of the formed steel. These sections or profiles are called girts in the building industry. There is a rising demand for girts and to meet this demand a c purlin machine manufacturer needs to work more or buy such steel purlin machines, which produce both the profiles. A cold roll forming machine makes c as well as z purlins simultaneously by switching back and forth quickly. But the c purlin machine manufacturer should take utmost care while using single machine for making both the profiles as a simple mistake can result in poor quality purlins.       

Purlin Shapes, Sizes and Profiles

Roll forming machine and steel purlin machine are used in making purlins. These machines form or bend cold-formed steel in to Cee and Zee sections. For convenience, the construction industry has named them as C and Z purlins or 'girts'. To keep pace with the increasing demand of girts, now manufacturers are producing both Cee and Zee sections on the same machine. The latest cold roll forming machine switches back and forth quickly thus producing both Cee and Zee profiles at the same time. But the c purlin machine manufacturer needs to be extra cautious while producing girts on the same machine. It must be noted that the slightest neglect can lead to poor quality girts which are of no use. 

How Steel Purlin's are Formed During Manufacturing

Advent of roll forming machines has made it much easier for manufacturers to produce purlin rails and other purlin products. Purlin is made by bending cold formed steel into Cee and Zee sections. In terminology, the Cee and Zee purlins are called girts. With a quick change over process, the manufacturer even produces both the profiles on the same roll forming machine. It helps the manufacturer in saving a lot of time and labor. But switching between two very different profiles need prudence because even a slight negligence can lead to poor quality produce, which is of no use for either party. Roll forming machines are not only used in making purlins but they are also used for punching holes in purlins. Sometimes roll forming machines have to be carried to the construction site for much accurate hole-punching in purlins.   

Girts and Purlin manufacturing machine

In metal construction for building roof systems purlins are frequently used and are manufactured by forming (or bending) cold-formed steel in to Cee and Zee (or Zed) sections.  Another name used for Cee and Zed (or Zee) sections in a wall construction is ‘girts’.

Top quality roll forming machines utilize a quick change over process for forming both profiles (Cee and Zee) on the same machine.  Because of this ability to switch between profile shapes it is very important to select a roll forming manufacture that has a history of providing Purlin Machines.  Switching back and fourth from shape to shape can lead to poor part quality if the equipment is poorly designed.  Top roll forming manufactures such as the Samco Machinery (Purlin Master) have proven their ability to produce both types of purlins on one machine. 

Mounting options for the common and not so common Purlin

Purlins are used to bridge a gap in the construction process and require a varity of mounting configurations.  Holes are punched in to the Purlin to provide standard mounting options for the installer.  The placement of these holes is critical and requires a well engineered rollforming machines that provides high accuracy.  Imagine the holes punched in to a Purlin with a large tolerance.  During installation on the job site they would have to modify and create new mounting assemblies.  This inefficient process would cause havoc at the construction site holding up delivery and increasing costs.  To overcome this some roll forming manufactures (http://www.industrial-machinery-news.com/roll-forming/smi) have developed specialized hole punching to solve this problem.  Samco Machinery offers a range of hole punching options to accommodate any pattern requirement.  From simple standard punching to flexible Punch Anywhere systems accurate hole punching is as critical as the trueness of any Purlin.
