Purlins are horizontal beams that serve as crucial structural supports. While they are commonly used for roofs, they can also be utilized on walls and floors. Their main purpose is to provide support on the roof deck, ensuring its durability against the elements and ability to bear its weight.

Common Types of Purlins
There are different types of purlins available, each tailored to specific applications. Understanding the characteristics and uses of these different types is essential to ensure the right choice for your project. These include the following:

C Purlins
As the name suggests, this type is shaped like the letter C with flattened sides. They’re lightweight and durable, making them perfect for supporting walls and floors. Because of their simpler shape and design, c purlins are easier to work with and install.
C purlins are great for simple span construction projects. Builders often use them to shape the shell and skeleton of the wall they’re building.
Z Purlins
The Z purlin type is specifically shaped like the letter Z, with one side broad and the other narrow. These types can be overlapped on top of each other for enhanced durability, making them much stronger than C purlins. Z purlins are ideal for larger and heavier structures.
In addition to their ability to bear heavier loads, the overlapping flanges also provide additional stability to the structure and improved resistance against bending. Their shape allows for versatility of use in roofing and other large-scale structures.

What To Consider When Buying Purlins?

It is crucial to consider the specific use case of the purlin before purchasing the right one. For larger constructions, the stronger z purlin is recommended, whereas if it is only a matter of supporting wall panels and floors, C purlins will suffice. Z purlins are better suited for heavier loads and larger projects, while C purlins are designed to handle less demanding loads.
