Structural Wood Corporation: Wood I-Joists

Wood I-Joists are engineered to be straighter, stiffer, stronger and more consistent in performance than solid sawn lumber. Engineered Wood I-Joists provide the owner with a superior floor, the builder with consistent quality for fewer call backs or complaints and the specifier with the confidence and versatility only Engineered Wood I-Joists can offer. See below for technical specifications. See the Inventory page for what's in stock.

When Structural Wood Corporation introduced the Engineered Wood I-Joist in 1969, it was perceived by many as a product of the future and today, it is the product of choice. During the 1980’s, most manufacturers decided to downsize their I-Joists and some continue to do so on a routine basis. Although these changes in profile and composition are mostly for competitive reasons, they often have a negative impact on the performance and benefits typically associated with an Engineered Wood I-Joist. Structural Wood Corporation took a different approach, promoting a wider flange and higher performance wood I-Joist. When determining what product is best for the application, L/480 deflection is not the only standard. We review factors such as actual deflection, vibration and economies of scale.
