Product Descriptions
In the steel industry, different purlin structural shapes were given representative names to facilitate the easy description of drawings and documents. Channel sections, with or without flange stiffeners, are usually referenced as C purlin; The channel section without flange stiffeners is also called U purlin. Point symmetry with a shape similar to the letter Z is called a Z purlin.
Automatic change CZ purlin roll forming machine can produce any specifications of the C&Z profiles (during the width 100~300), no need changing any parts of the machine. It takes one hour to change C shape to Z shape.

Application
In steel construction, purlins generally refer to the roof framing members that run parallel to the eaves span of a building and support the roof deck or decking. Purlins are supported by beams or walls. Purlins are most commonly used in metal building systems, where they are used in a Z-shape to allow for flexural continuity between spans.
Auxiliary members such as purlins (roofs) and ring frames (walls) are usually C-shaped, Z- shaped or U- shaped steel (or rolled) C- shaped steel.
