The Purlin Mill located in Hubbard, Oregon is the only manufacturer of purlins and girts specializing in the
pre-engineered steel building market in Oregon.

After experiencing decades of quality and service issues from other vendors, the current owners dreamed to someday start their own purlin manufacturing facility; A business incomparable to the vendors of the past employing people of integrity who actually care for the customer and take pride in the quality and service they provide.

The owners dreams finally came true in January 2008 when The Purlin Mill ( TPM ) opened its doors for business in a brand new 17,000 square foot manufacturing facility with a small team of exceptional people who are still with us today and a new automated roll former capable of manufacturing multiple profiles with fast changeovers.

Shortly after opening, TPM purchased another new roll form machine to manufacture their our own Architectural Standing Seam Roofing (SSR-18) panel.

TPM currently manufactures: Zee’s, Cee’s, Eave Struts, Open Channel, Angle, Purlin & Girt Clips and our SSR-218 roofing panel.

Located in the Pacific Northwest, TPM takes extra precautions to protect our steel products from corrosion. Our steel is hot dipped galvanized to a G-90 classification to ensure the longevity of our product. This is a heavier galvanized coating than many other manufacturers.

The Purlin Mill manufacturers components for: The pre-engineered steel building market, other component manufacturers, sheet metal companies, mini storages, door companies, carports, modular buildings, mining conveyor systems, mezzanines, floor joists and many other uses.
