Gauges and thicknesses
| Gauge | Bare steel thickness (in) | Weight (lbs/ft) | Typical applications |
|---|---|---|---|
| 12 | 0.094 | Up to 6.78 lbs/ft | Heavy structural applications, large spans. |
| 14 | 0.075 | Up to 5.4 lbs/ft | Standard commercial structural support. |
| 16 | 0.059 | Up to 3.02 lbs/ft | Medium-duty roof and wall support. |
| 18 | 0.047 | Up to 1.94 lbs/ft | Light-duty applications. |
| 20 | 0.039 | Up to 1.35 lbs/ft | Light framing and small spans. |
Gauges 12 to 20 give you room to balance load against span. Use the heavier 12 and 14 gauges for big structural applications and heavy roofing loads. Where weight and cost efficiency come first, such as light framing and small spans, the lighter 18 and 20 gauges are the fit.
Finishes and coatings
| Finish | Details |
|---|---|
| Galvanized G60 | Zinc coating of 0.6 oz/ft². Recommended for general environments. |
| Galvanized G90 | Zinc coating of 0.9 oz/ft². Ideal for highly corrosive environments. |
| Prime-Painted | Provides a base coat for additional protection or paint adhesion. |
| Bare Steel | Unfinished; typically for indoor use or controlled environments. |
C purlins are supplied galvanized (G60 and G90) or prime-painted. G60 protects against corrosion in general environments, and G90 has a thicker zinc layer for coastal or high-humidity work. The prime-painted option supplies a base coat when additional coatings will follow.
Material and finish options
Our C purlins use 55 KSI high-strength steel. Finishes include corrosion-resistant galvanizing that meets ANSI standards, paint for a tailored appearance, and bare steel for custom applications, each designed to boost durability and performance on West Palm Beach projects.
Custom lengths
Lengths start at 6′-0″ for smaller jobs and stretch to 40′-0″ for large construction. We cut each piece precisely, so the purlins fit well and little material is wasted on West Palm Beach job sites.
C Purlin features
High strength-to-weight ratio, easy installation, and corrosion-resistant finishes make our C purlins a good fit for industrial buildings, solar panels, agricultural structures, and commercial roofing and wall systems.
High Strength-to-Weight Ratio
Carries heavy loads yet stays light, which lowers structural dead load and makes handling and installation easier.
Easy and Fast Installation
A lightweight, symmetrical section cuts labor hours and simplifies erection in roof and wall systems.
Galvanized or Prime-Painted Finish
Choose G60 or G90 galvanized, or prime-painted, for better durability and corrosion resistance.
Ideal for Custom Applications
Works across industrial buildings, solar panels, agricultural structures, and many other commercial structural uses.
Compliance with SDI Standards
Conforms to Steel Deck Institute and ANSI guidelines for quality and code compliance.
Versatile Design Options
Sizes from C4x2 to C12x3 and gauges 12 to 20 cover a wide spread of structural needs and loads.
Installation and connections
Installation practices
- Place C purlins perpendicular to primary structural supports.
- At each support, anchor with bolts, welds, or self-drilling screws.
- Overlapped purlins are secured with bolts or screws at 12" o.c.
Fasteners and attachments
- ½" Diameter Bolts for secure connection to primary frames
- #12 Self-Drilling Screws at 6" o.c. along supports and 12" o.c. at overlaps
- Overlapping joints fastened with #12 Self-Drilling Screws at 12" o.c.
Confirm the profile, gauge, span, loads and connections against your project drawings and the applicable product load tables before ordering.
Applications
Roof and Wall Structural Framing
Commercial and industrial buildings use C purlins as solid support for roofing and wall cladding, in vented and non-vented structures alike.
Mezzanine and Racking Support
Strong enough for mezzanine floors and industrial racking, they are a dependable option for warehouses and factories.
Standards and product documentation
This C purlin is built to SDI (Steel Deck Institute) specifications, which sets a high bar for design and performance.
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.
