Know Your Product
C Purlins vs Z Purlins
Both profiles serve structural roofing — understanding the difference helps you specify the right purlin for your project.
C Purlins
Shape:Cross-section looks like the letter "C" — single-web with two flanges on the same side.
Applications
- •Ideal for simple roof and wall structures.
- •Commonly used in supporting walls, beams, and floor joists.
- •Typically installed at the ends or corners of a structure.
Advantages
- •Lightweight yet strong — reduces dead load on the structure.
- •Easy to install and transport to site.
- •Good for short to medium span roofing support.
Z Purlins
Shape:Cross-section shaped like the letter "Z" — asymmetric flanges allow nesting and lapping at joints.
Applications
- •Ideal for long-span roofing where extra strength is needed.
- •Used in intermediate spans where overlapping sections are required.
- •Allows easy lapping or nesting, giving extra strength to joints.
Advantages
- •Stronger than C purlins due to lapping design at joints.
- •Excellent for large-span warehouses and industrial sheds.
- •More economical in overlapping sections — less material for the same span.
