Quizplus · Accepted Answer

The term "finger-jointed" refers to a method of joining short pieces of solid wood together to create longer pieces. This technique is commonly used in the production of wood I-beams because it allows for greater use of smaller pieces of wood, reducing waste and increasing efficiency. Double and toe joints are not commonly used in the production of wood I-beams, and reciprocally jointed lumber is not typically used for flanges.
