C purlins in Tallahassee
High-strength C steel purlins in Tallahassee for efficient roof and wall support in commercial and industrial construction.
Supplying C Purlins in Tallahassee
General contractors and steel erectors in Tallahassee rely on Miami Metal Deck for C Purlins on projects across Leon County and the North Florida / Panhandle region. Deliveries to Tallahassee leave our Miami Gardens facility on a schedule set with your team, with 1-day service available to major Florida cities.
For inland Tallahassee projects, G60 galvanized is often sufficient for enclosed structures, while G90 remains available where the specifications call for more corrosion protection. Projects in Tallahassee follow the Florida Building Code wind-load requirements, so we work directly from your engineer's deck schedule, gauges and attachment details.

C Purlin
Roof and wall applications commonly use C purlin because it is both strong and light. This C-shaped section comes in depths and gauges from 12 GA to 20 GA, follows ANSI standards, and is finished with G60 or G90 galvanizing.

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 Tallahassee projects.
Custom lengths
Need 6′-0″ pieces for a smaller project or spans of up to 40′-0″ for a larger one? We handle every length precisely and efficiently. Custom cutting gives an optimal fit with minimal waste.
C Purlin features
Our C purlins pair a high strength-to-weight ratio with simple installation and corrosion-resistant finishes. Contractors in Tallahassee can specify them for industrial buildings, solar panel racking, agricultural structures, and commercial roofing and wall systems.
High Strength-to-Weight Ratio
Strong load-bearing performance in a light section means less dead load on the structure and easier installation.
Easy and Fast Installation
Because the section is light and symmetrical, crews spend less time and face fewer complications in roof and wall systems.
Galvanized or Prime-Painted Finish
G60 and G90 galvanized finishes, along with prime-painted, improve durability and corrosion resistance.
Ideal for Custom Applications
Fits industrial buildings, solar panels, agricultural structures, and a variety of other commercial structures.
Compliance with SDI Standards
Steel Deck Institute and ANSI guidelines are met, supporting quality and code compliance.
Versatile Design Options
Choose from C4x2 to C12x3 sizes in gauges 12 to 20 to suit different structural needs and load requirements.
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
SDI (Steel Deck Institute) specifications govern the C purlin, so design and performance meet a high standard.
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 Tallahassee?
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.
