Z Section PurlinsZ Section Purlins are generally manufactured from GALVASPAN® steel and are roll formed into Z Section. Metroll Z Section Purlins have one broad and one narrow flange. These are designed to fit neatly and are used for lapping at the internal supports producing structurally continuous lines of purlins for the length of the building. Structural continuity results in improved rigidity, but lapping doubles the thickness of the purlin over the supports where the bending movement is the greatest. This saves 30-50% of steel in purlins relative to C Section Purlins. When additional purlin strength is needed Z Section Purlins of the same depth but greater thickness can be lapped as needed. Structural applications include grain or coal handling facilities and manufacturing facilities.
