Section Sizes, Dimensions & Properties

Z Sections:

Z Section Duro Purlins can be lapped over interior supports of multi-bay buildings to produce a structurally continuous line throughout the length of the building. Lapping results in better economy and provides double thickness of material over interior supports, thus improving their load rigidity, and increasing the capacity of the sections to resist bending moments.
