Woodfold Manufacturing is a Portland-based producer of custom-built space-dividing solutions, including accordion doors, acoustic partitions, security doors, elevator doors and roll-up doors. Operating since 1957, they specialise in high-quality hardwood products for commercial, residential, institutional and industrial settings. The company is employee-owned and sells exclusively through a dealer network, so referrals work best if you direct clients to their dealer locator rather than approaching them directly.
