Introduction
Based in Hubbard, Oregon, The Purlin Mill is one of the region’s only manufacturers dedicated to producing precision secondary structural components for the pre-engineered metal building (PEMB) and structural steel component markets. With a focus on quality, efficiency, and regional expertise, The Purlin Mill supplies the backbone of countless commercial, agricultural, industrial, and residential steel structures throughout the Pacific Northwest.
Who We Are
Operating from a 17,000 sq. ft. production facility, The Purlin Mill is equipped with state-of-the-art machinery, including a 162-foot automated Mark II roll-forming line, Jorns Heavy Gauge Double Folding Machine, Schlebach MASTERCUT slitting system, and Stealth Night Hawk SS2015CP 8000-Watt Laser Cutting Machine. Together, these systems allow us to manufacture Z-purlins, C-purlins, eave struts, open channels, structural angles, trims, flat sheet products, roofing, wall systems, and custom steel components with unmatched precision and efficiency.
What We Offer
At the heart of The Purlin Mill’s product lineup are galvanized steel building components and architectural panel systems, designed to meet the structural and aesthetic needs of today’s construction market.
Structural Components
- Z Purlins & Girts — Structural “Z”-shaped members used to support roof loads.
- C Purlins & Girts — Versatile “C”-shaped members for purlins, girts, base channels, and framing.
- Eave Struts — Load-bearing members at the edges of roof systems.
- Open Track — C-shaped channels for end wall capping, base channels, and steel stud foundations.
- Structural Angle — Multi-purpose angles for a wide range of applications.
- Accessories — Including purlin & girt clips, nuts, bolts, custom clips, and fabricated parts.
Standing Seam Roofing: SSR-218 Panel
The Purlin Mill not only manufactures Zee and Cee purlins but also produces the SSR-218 Standing Seam Roofing Panel — a concealed fastener, mechanically seamed panel engineered for superior weather resistance. Each panel includes factory-applied non-skinning butyl mastic to ensure long-lasting protection against air and water infiltration.
The SSR-218 is commonly specified for low slope and architectural roofing applications, making it ideal for both commercial and residential projects. With its clean lines, energy efficiency, and proven durability, this panel offers both performance and visual appeal.

Core Features:
- Coverage Width: 12″
- Panel Rib Height: 1-1/4″
- Panel Attachment: Concealed fastener system
- Gauges: 24-gauge standard, 22-gauge optional
- Panel Lengths: Custom lengths from 4’–0” to 40’–0”
- Installations: Vertical or horizontal
- Finishes: Smooth
- Coatings: Zincalume Plus, Cool PVDF, and PVDF Printech Wood Grain Series
The High Caliber Series delivers a refined architectural appearance, ensuring every project achieves both the custom look and the long-term durability today’s builders and architects require.

Why Choose Steel Building Materials?
Steel is the future of construction, and The Purlin Mill provides the components that make it possible. Compared to traditional materials, steel building systems offer clear advantages:
- Durability & Low Maintenance — Resistant to mold, mildew, pests, and rot.
- Strength-to-Weight Efficiency — Among the highest strength-to-weight ratios of any building material.
- Design Flexibility — Works as a standalone system or in combination with other materials.
- Structural Integrity — Delivers stronger, more reliable connections than wood framing.
- Fire Resistance — Non-combustible, potentially reducing insurance costs.
That’s why The Purlin Mill’s products — purlins, girts, trims, roofing, wall systems, and architectural panels — are trusted across industries including commercial, industrial, retail, manufacturing, warehousing, recreational, and agricultural.
Advanced Roll Forming
Accuracy and consistency are built into every component we produce:
- Inkjet-Printed Identification — Job numbers and piece marks for easy assembly on-site.
- Computer-Controlled Hole Punching — Precision punching based on customer-supplied charts ensures accuracy and cost efficiency.
