C-section purlins are a type of purlins manufactured in the shape of the letter “C”.
They have flanges whose dimensions are equal and are mainly used in the support of wall joists and roofs.
The C-section purlins are used in single spans.
Zee purlins, also referred to as Zee Purlins, are named from the letter Z. They are Z shaped and have a significant difference from C purlins.
They are stronger compared to C-section purlins. Unlike the C-section purlins, the flanges are not the same.
In terms of usage, Zee purlins are ideal for large buildings and also smaller or light buildings and projects such as carports and garages.
