C Purlin Selection: Don't Look Only at the Thickness
A C purlin's performance depends on the complete section, not just its steel thickness. Web height, flange size, lip size and thickness work together to determine the section's stiffness and load capacity. Emaar offers C purlins with 152–302 mm web heights, different flange and lip sizes, 1.5–3.0 mm thicknesses and customized punching options.

What is the advantage of a C purlin over a Z purlin?
