In structural engineering, construction and architecture, a purlin is a horizontal beam that will provide structural support for the roof and wall system in a building.
Just like C purlins, Z purlins derive the name from the shape of the letter Z.
The shape of the purlins helps in overlapping the joints that, make them sturdier and stronger compared to the C purlins. Because of their strength, Z purlins are used for large span structures.
Purlin span is the distance between the centers of each purlin. Each type of span represents a complete purlin system. There are three types of purlin span systems.
Advantages of Z purlins
Z purlins can be overlapped
Significantly saves material by reducing the height of the purlins
