Our Products

Zip-O-Log Mills, Inc. has been a leading provider of quality Douglas Fir products for more than 75 years. We are a long length cutting sawmill with the capacity to produce up to 52′ in length. Because our products are produced for exposed structure applications, Zip-O specializes in #1 & better, free of heart center timbers. We also produce boxed heart timbers.

Anti-stain and application of a clear wax base end seal is applied to all rough products and we offer anti-stain treatment on surfaced products as well (all surfaced timbers are end sealed). Other available options to protect products during handling and shipping are paper wrapping, bottom boards, and stickers with lath or kiln stickers on every layer if the customer requires. We ship by Rail or Truck.

Zip-O’s wide-ranging product line, knowledgeable sales staff, and dedicated employees ensure that your order will have accurate tallies, on time shipments, and quality that exceeds your expectations. Contact our sales staff, we can fill your custom order needs.
