Spruce wood is generally not considered highly rot-resistant compared to other types of wood, such as cedar or redwood. It has a moderate durability rating and is susceptible to decay when exposed to moisture. To enhance its longevity, spruce should be treated with preservatives or used in conditions where it remains dry. Proper maintenance and finishing can also help protect it from rot.

Titanium is highly corrosion-resistant.
Redwood and Wolmanized Lumber
