IBR roofing panels can display a variety of structural properties in a variety of materials.
It should be noted that the load span characteristics are used only as a broad guideline, as the purlin spacing depends on other factors such as:
The prevailing wind in a given area,
Snow during winter periods,
The presence of dust and other particles in industrial areas, as well as the types of structures being established
Therefore, we recommend consulting a qualified engineer to determine the purlin spacing for a particular application.
