What Zip-O-Log Mills does

Zip-O-Log Mills is a fourth-generation, family-owned manufacturer of specialty Douglas Fir lumber products, headquartered in Eugene, Oregon since 1951 and operating the Goshen Mill (acquired 2013) as a downstream planer and sorting facility. The company's core product is long-length Douglas Fir timbers — produced in lengths up to 52 feet, in #1 & better grade with free of heart center (FOHC) specification — along with posts and beams, crossarms, specialty timbers, and stocking items serving exposed structural and timber frame construction end-uses. Underlying technology centers on physical manufacturing assets: log scanning equipment (installed 1980, upgraded 2002 for 52-foot capability), modern dehumidifying kilns, and surfacing capacity up to 20" x 30", with raw dimensions sawn up to 48" x 48". The company reports zero log waste, with bark, chips, shavings, and pallet-grade wood sold into landscaping, playground surfacing, agriculture, and pallet stock channels.

The business model is B2B wholesale-only: products are sold exclusively through wholesale stocking distributors and office wholesalers (with rail and truck delivery options including Union Pacific and Burlington Northern rail lines), never directly to contractors or end consumers. Pricing is not publicly disclosed and is negotiated per inquiry. Named wholesale customers include U.S. Lumber Group, Western Woods, Mid-Atlantic Timberframes, Allweather Wood, Weekes Forest Products, Taiga Building Products, and All-Coast Forest Products — with several relationships exceeding 20 years. In 2016 the company created sister brand Zip-O-Laminators (custom glulam beams), enabling combined truck-load shipments that reduce customer transportation costs. After divesting Pennington Crossarm in 2017 to focus on core operations, the company is now executing its largest capital expansion in company history: an approximately $18 million headquarters relocation and renovation in Eugene targeted for completion in late 2026, paired with planned Goshen Mill production capacity increases.

Revenue is not publicly disclosed; headcount is reported in the 101–250 range. Ownership remains entirely within the Hallstrom family, with Karl Hallstrom joined in 2021 by daughters KayCee and KelCee as co-owners, and professional management in place including CEO James Workman and COO John Redfield.
