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 and agricultural buildings. |
Z Purlins are available in gauges 12 through 18, providing options for varying load and span requirements. Heavier gauges (12 and 14) are ideal for large structural applications. Lighter gauges (16 and 18) suit medium to light-duty applications in commercial and agricultural structures.
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. |
Z Purlins come in galvanized (G60 and G90) and prime-painted finishes. G60 provides corrosion resistance for general environments. G90 offers enhanced zinc coating for coastal or high-humidity applications. Prime-painted adds a protective base coat for projects requiring additional coatings.

Z Purlin features
Elevate your projects with our Z Purlins, featuring superior load-bearing capacity, overlapping design for extended spans, and corrosion-resistant finishes. Ideal for large-scale commercial, industrial, and agricultural roofing and wall systems.
Superior Load-Bearing Capacity
Engineered to handle higher structural loads with the overlapping design providing continuous-span structural efficiency.
Overlapping for Extended Spans
Z purlins overlap and interlock at intermediate supports, creating continuous-beam behavior for greater structural efficiency over longer distances.
Corrosion-Resistant Finishes
Available in G60 and G90 galvanized or prime-painted finishes for excellent durability and resistance to harsh environmental conditions.
Cost-Effective
Longer spans with fewer intermediate supports reduce material and labor costs for large-scale roofing and wall systems.
Compliance with SDI Standards
Meets Steel Deck Institute and ANSI guidelines, ensuring quality and code compliance.
Versatile Applications
Multiple sizes (Z6x2.5 to Z12x3) and gauges (12–18) for commercial, industrial, and agricultural structural applications.
Installation and connections
Installation practices
- Install Z Purlins perpendicular to primary structural supports.
- Anchor at each support using bolts, welds, or self-drilling screws.
- Overlap and interlock purlins at intermediate supports, secured 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
Long-Span Roofing Systems
Z purlins are ideal for large-scale commercial and industrial roofing systems requiring continuous spans and fewer intermediate supports. The overlapping design maximizes structural efficiency across long roof runs.
Continuous Wall Cladding Support
Z purlins provide continuous wall girt support for metal cladding systems in industrial, commercial, and agricultural buildings, offering superior lateral stability through the interlocking profile.
Standards and product documentation
The Z Purlin complies with SDI (Steel Deck Institute) specifications, ensuring high standards for design and performance.
Z Purlin questions
What is a Z Purlin and what is it used for?
A Z Purlin is a cold-formed steel structural member shaped like the letter 'Z', used primarily as roof purlins and wall girts in commercial, industrial, and agricultural metal building systems.
What is the advantage of Z Purlins over C Purlins?
Z purlins can overlap and interlock at intermediate supports, creating continuous-beam behavior that provides greater structural efficiency and load capacity over longer spans compared to simple-span C purlins.
What sizes and gauges are Z Purlins available in?
Available 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.
What finishes are available for Z Purlins?
Available in G60 and G90 galvanized finishes for corrosion resistance and prime-painted finishes for projects requiring additional coatings.
Can Z Purlins be customized?
Yes, custom Z Purlins are offered tailored in length (6' to 40'), gauge, and finish to meet specific project specifications.
