Final answer:

Lightweight wooden I-beams, also known as I joists, are comprised of Laminated Veneer Lumber (LVL) for the flanges and Oriented Strand Board (OSB) for the web, creating a strong and flexible beam used in construction.

Step-by-step explanation:

The lightweight wooden I-beams, commonly referred to as I joists, are a combination of two engineered wood products: Laminated Veneer Lumber (LVL) and Oriented Strand Board (OSB). These materials are used together to create a strong and lightweight structural beam. The LVL is typically used for the flanges of the I-beam, providing the strength necessary to support loads, while the OSB is used for the web, the part of the beam that separates the flanges and provides stability. These I-beams are favored in construction due to their strength, consistency, and the fact that they can be manufactured in longer lengths than traditional lumber.
