C Purlin questions
What is a C purlin, and what is it used for?
It is a cold-formed steel member with a 'C' shaped section. Its main job is structural support in the roofs and walls of industrial, commercial, and agricultural buildings.
How does a C purlin differ from a Z purlin?
The C purlin has a symmetrical 'C' section that gives strength and stability, and it works best in simple-span applications. A Z purlin has a 'Z' section that lets pieces overlap, which adds rigidity on longer continuous spans.
Which gauges and materials do C purlins come in?
Gauges 12 to 20 are available. They are made from galvanized steel (G60/G90) or prime-painted steel, depending on what the project requires.
What are the benefits of C purlins in Jacksonville?
They offer high structural strength in a light profile, quick installation thanks to a standardized design, and flexibility across building types. Galvanizing adds corrosion resistance, and durability keeps maintenance and cost down.
Are custom C purlins available?
Yes. We make custom C purlins to order, with length (6' to 40'), gauge, and finish set to your project specifications.

Do you supply steel purlins in Jacksonville?
Yes. We deliver C and Z purlins to Jacksonville with 1-day delivery available. Contact us at 305-760-2575.
What is the difference between C and Z purlins?
Z purlins overlap and interlock at supports for continuous-span efficiency. C purlins suit simple-span applications where continuity is not required.
Why are steel purlins used?
They support roof and wall sheeting, moving load from the cladding into the main structural frame. Purlins run horizontally across the rafters or columns of a building.
What are the usual steel purlin types for Jacksonville buildings?
C and Z Purlins are the most common. Simple, non-overlapping spans suit C Purlins, and Z Purlins overlap and interlock for continuous spans with greater structural efficiency over long distances.
What is the main difference between C and Z Purlins?
Continuous beam behavior is more efficient with Z purlins, because they overlap and interlock at intermediate supports. C purlins serve simple spans, where continuity is not needed.
Can one purlin type serve both roofs and walls?
Yes. Both C and Z purlins serve as roof purlins that support roof panels and as wall girts that support wall cladding, which makes them flexible parts of metal building systems.
Which coatings come on purlins?
Purlins are all available in galvanized steel, with G90 or G60 coatings for corrosion resistance and lasting performance in commercial, industrial, and agricultural settings.
