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 West Palm Beach?
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.

Z Purlin questions
What is a Z purlin used for?
A Z purlin is a cold-formed steel structural member shaped like the letter 'Z'. Roof purlins and wall girts in commercial, industrial, and agricultural metal buildings are its main uses.
What does a Z purlin do better than a C purlin?
It overlaps and interlocks at intermediate supports, which creates continuous-beam behavior. Compared with simple-span C purlins, that means greater efficiency and load capacity across longer spans.
Which sizes and gauges are available for Z purlins?
They run from Z6x2.5 to Z12x3 in gauges 12 through 18, with web depths from 6 to 12 inches and flanges from 2.5 to 3 inches.

Frequently Asked Questions
Do you supply steel purlins in West Palm Beach?
Yes. We deliver C and Z purlins to West Palm Beach 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.
What is the function of a steel purlin?
A steel purlin supports roof and wall sheeting. It transfers loads from the cladding to the main structural frame and runs horizontally across the rafters or columns of the building.
Which purlin types do most buildings use?
Most use C or Z Purlins. C Purlins are chosen for simple, non-overlapping spans. Z Purlins overlap and interlock to form continuous spans, giving better structural efficiency over long distances.
What distinguishes a C Purlin from a Z Purlin?
At intermediate supports, Z purlins can overlap and interlock, giving more efficient continuous beam behavior. C purlins are used in simple spans where that continuity is not required.
Are purlins suitable for roof and wall support?
They are. C and Z purlins serve as roof purlins for roof panels and as wall girts for wall cladding, which is why metal building systems use them so widely. Contractors in West Palm Beach use both.
Which materials and coatings can I order?
Galvanized steel with G90 or G60 coatings is available for every purlin, giving corrosion resistance and long-term performance in commercial, industrial, and agricultural environments.
