Fiber Products

Sierra Pacific Industries continues to seek new and innovative methods to utilize 100% of its forest resource. During each sawing and milling operation, state-of-the-art technology, machinery, and skilled operators yield the maximum wood fiber from the logs or lumber. Chips, bark, shavings, and sawdust are the by-products that are produced from lumber and millwork manufacturing. Today, 100% of the wood fiber coming from the forest is used in one form or another to provide products for consumers.
