Roof Purlins in Steel Structure
There are many components that contribute to the stability of a metal building. When it comes to roofing, metal purlins are a critical element needed to give the structure proper support.
Red Ocean Contracting has been providing clients with the roof purlins solutions for a successful installation for years.
Types of Metal Roof Purlins
Not all metal purlins are the same as they come in different types and sizes. Therefore, it is important for you to know the differences and use the right purlin for your project.
Purlins are an important component in a pre-engineered steel structural kit. These structural supports run perpendicular across the rafter beams.
Also known as “sheeting rails,” purlins create the roofing members of the secondary steel structure framing of a steel building.
Why are Purlins Used?
Metal building roof purlins provide three structural functions:
- First, the purlins support the roof.
- Secondly, purlins tie the rafters together, stabilizing and strengthening the structure’s rigid framing.
- Thirdly, purlins add additional support between the spans of the individual framing bays.
- As an added bonus, metal roof purlins increase the structure’s resistance to strong winds.
Steel Building vs. Wood Building Roofing
Wood framing employs decking to tie roof trusses together and support the roof. Decking is heavy and expensive. It is also time-consuming to install, driving up labor costs.
Steel building purlins eliminate the need for oriented strand board (OSB) or plywood decking. Consequently, a metal building system saves money on both building material and labor.
