Step-by-step explanation:
Headers, beams, and portions of wood I-joists can be cut from lumber. Lumber is versatile and can be cut into various stock shapes and sizes to meet the specific requirements of construction projects.
For example, headers are typically made from dimensional lumber, such as 2x4 or 2x6 boards. Beam size and shape depend on the load-bearing requirements and span of the structure. Common materials used for beams include solid lumber, laminated veneer lumber (LVL), and engineered wood products like glulam beams.
Wood I-joists, which are often used in residential construction, consist of an engineered wood flange and a structural panel web. They are manufactured in standard stock sizes, but can also be cut to specific lengths to accommodate different construction needs.
