What are C purlins?
A C purlin is a steel material used for the construction and structural integrity of walls and roofs. The “C” shape of the purlin supports the load either from the roof or the wall.
C purlins are often made using cold rolling. Cold-rolling helps to form strong steel, which is necessary for the safety of a new construction project. When using steel, it is important to use specific grades, typically DX51 to S350-S550. These are the best and most conventional for welding, as they are lightweight and durable.
How do Purlins hold up wall and floor joists?
Purlins hold up wall and floor joists with their special “C” shape edges. They are horizontal and supported by struts, which work to hold them in place against the wall, roof, or floor,
When put into place, purlins help to carry the load from the roof onto the strut.
To understand what floor and wall joists are, it is simply a frame that supports the opposing wall or floor. For instance, when constructing new mezzanine flooring, C purlins are used to take the load off of the new floor and struts. They provide support and help to improve structural integrity.
What is the difference between a beam and a purlin?
It is important not to get beams and purlins confused. A beam is used as a secondary source of support. Whereas a purlin is the first source of support to hold up a structure and support the load.
Beams are used for walls, floors, and roofs. Whereas purlins are mostly used for roofs.
How Far Apart Should C Purlins Be Spaced for ultimate structural integrity?
It is important to space C purlins correctly for ultimate structural integrity.
The minimum spacing is 900 mm (0.9 metres) and the maximum is 1,200 mm (1.2 metres).
Importance of Correct Spacing for C Purlins in The Construction Industry
It is essential to space these correctly in the construction industry as it helps with counting the number of purlins that could be needed.
Furthermore, proper spacing that meets industry standards will work to improve structural integrity.
