What is the common size for LWP Beams?

Explanation:
The main idea is that a beam’s strength in bending largely comes from its depth. A cross-section that is 36 inches deep provides a much larger moment of inertia than the other options, giving higher bending capacity for typical long-span loads. In laminated or built-up wood beam applications, this deep 6-by-36 inch section is a standard, widely stocked size that balances strong performance with practical handling and availability. The other dimensions either don’t offer enough depth to meet common load requirements or are less practical from sourcing and weight perspectives, making them less typical as a standard LWP beam size.
