What Is Sequoia Wood Used For: Then and Now

Sequoia wood has been used for fence posts, shingles, vineyard stakes, lumber, and decorative items, though its applications have always been limited by the wood’s natural brittleness and, more recently, by legal protections on old-growth trees. Today, most sequoia wood in circulation is either reclaimed from old structures or harvested from younger, plantation-grown trees, and it finds its way into furniture, siding, and specialty woodworking.

Two Trees, Two Kinds of Wood

The word “sequoia” covers two distinct species, and the difference matters for woodworking. Coast redwood is the tall, slender tree that has been commercially logged for over a century and remains an important timber species. Giant sequoia is the massive, barrel-shaped tree found mostly in California’s Sierra Nevada. Coast redwood has always been the more commercially important of the two because its wood is more workable and more resistant to decay. Giant sequoia wood has a reputation for being very brash, meaning it snaps rather than bending, which makes it poorly suited for structural beams or anything that needs to absorb impact.

That said, US Forest Service research has found that younger giant sequoia trees produce wood with properties comparable to, or even slightly better than, coast redwood in terms of weight, strength, and natural chemical resistance. Young-growth giant sequoia is heavier and stronger than old-growth giant sequoia, which is the opposite pattern from coast redwood. So the brittleness problem is primarily an old-growth issue, and younger trees may eventually fill some of the same roles as redwood lumber.

Historical Uses During the Logging Era

During the late 1800s and early 1900s, loggers felled many giant sequoias, only to find that the massive trunks often shattered when they hit the ground. The wood that survived intact was too brittle for construction beams, so it was turned into products that didn’t require structural strength: fence posts, vineyard stakes, shakes, shingles, and occasionally dimension lumber for areas with high decay risk. The wood’s natural resistance to rot made it practical for anything that would sit in or near the ground.

Some sequoia wood was fashioned into novelty and decorative items. At the 1893 Chicago World’s Fair, visitors could see cigar boxes and souvenir canes made from sequoia wood, now part of a collection held by Stanford Libraries. These artifacts reflected the era’s fascination with the trees’ sheer size more than any particular quality of the lumber itself.

Coast redwood, by contrast, became a mainstream building material. Its old-growth wood was prized for low shrinkage, fine texture, and strong decay resistance. It was widely used for siding, doors, window sashes, blinds, and interior finish work. In settings where rot was a concern, redwood went into cooling towers, water tanks, silos, outdoor furniture, and split fence products. It also made excellent decorative plywood.

Why Sequoia Wood Resists Rot

Both sequoia species owe their durability to chemical compounds in the heartwood. The core wood of these trees contains extractives, naturally occurring substances that are toxic to fungi and insects. Coast redwood heartwood contains roughly 10% extractives by weight, which helps explain why it ranks among the most decay-resistant softwoods in the world. When researchers removed these extractives from redwood samples using a solvent, the wood’s resistance to white rot fungus dropped dramatically, with weight loss nearly doubling in lab tests.

Giant sequoia heartwood contains similar protective compounds, though its overall decay resistance is lower than coast redwood’s. This still puts it ahead of many common softwoods. The practical result is that sequoia wood holds up well in outdoor applications where moisture and soil contact would quickly destroy pine or fir.

Fire Resistance of Sequoia Bark

Sequoia trees are famous for surviving wildfires, and this is mostly a bark story rather than a wood story. Both species develop exceptionally thick bark, sometimes exceeding a foot on mature giant sequoias. This bark insulates the living tissue underneath during ground fires. Coast redwood bark thickness varies by tree size, stand density, and even latitude, with trees in drier, more fire-prone southern areas tending to develop thicker bark. The bark itself is often partially consumed in non-lethal fires, which means the thickest bark near the base of large trees may actually be thinner than bark higher up the trunk, because repeated fires have burned away the outer layers over centuries.

The wood itself is not fireproof, but the combination of thick bark and high moisture content in living trees gives sequoias a survival advantage that few other species can match.

Modern and Reclaimed Uses

Almost all old-growth giant sequoia groves are now protected within National Parks and other reserves, so fresh logging of these trees is essentially nonexistent. The giant sequoia wood available today comes from three sources: reclaimed lumber salvaged from old buildings and structures, wood from trees that fell naturally, and timber from younger plantation-grown trees.

Reclaimed sequoia wood is valued for its rich, reddish-brown color and straight grain. Craftsmen and specialty furniture makers use it for dining tables, shelving, wall paneling, and decorative pieces. The appeal is partly aesthetic and partly symbolic. A slab of old-growth sequoia carries visible history in its tight grain rings, and buyers are drawn to the story embedded in the material. Reclaimed wood shops, particularly in California, carefully deconstruct old sequoia lumber and repurpose it for flooring, furniture, and architectural details.

Young-growth giant sequoia has more practical potential. Forest Service research found that it works well as veneer, with properties comparable to coast redwood veneer, which is rated excellent for decorative siding. It also meets standards for dimension lumber in light construction. Researchers have recommended that giant sequoia be considered as planting stock in managed production forests to supplement the supply of decay-resistant softwood, a role traditionally filled by coast redwood, incense cedar, and western red cedar.

How It Compares to Other Softwoods

Young-growth giant sequoia matches or slightly exceeds white fir, incense cedar, western red cedar, and young-growth coast redwood in most mechanical properties. That places it solidly in the middle tier of construction softwoods: strong enough for framing, decking, and fencing, but not a replacement for Douglas fir or southern pine where high load-bearing capacity is needed.

Its real advantage is the same one that made redwood famous: natural resistance to decay without chemical treatment. In a market where pressure-treated lumber dominates outdoor construction, untreated wood that can handle ground contact and moisture has a clear niche. For garden beds, fence posts, planters, and outdoor furniture, sequoia wood offers a chemical-free alternative that weathers gracefully over decades.
