1. Dimensions and geometrical properties
The Z-section has one wide and one narrow wing, sized so that two sections of the same size can overlap making them suitable for overlapping.
Purlins with continuous lengths are more economical, but overlapping joints double the metal thickness at mid span supports. Overlapping increases the strength of the section at the position with the greatest bending moment and shear force, thereby increasing the load capacity and rigidity of the system.
Z-purlins of the same height but different thicknesses can be superimposed with any combination.
Z-beams can also be used in simple spans. For shorter spans, two or more spans can be used continuously without overlapping, thus reducing the deflection compared to a simple span but without giving the strength advantage of a superimposed system.
2. Outstanding advantages
– The ability to overcome great beats
– Simple installation, low cost
– Sustainable beauty
– Wide range of sizes and thicknesses, suitable for all apertures and designs
– Warranty against corrosion
Things to note when choosing to buy Z purlins
