Structural Composite Lumber (SCL)

What is Structural Composite Lumber?

Structural Composite Lumber (SCL)

Structural composite lumber (SCL) is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture-resistant adhesive into blocks of material known as billets, which are subsequently resawn into specified sizes.

SCL includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL). The term SCL was coined to capture a wide array of products, some of which are proprietary or unique to one manufacturer. In SCL billets, the grain of each layer of veneer or flakes runs primarily in the same direction.

SCL is a solid, highly predictable, and uniform engineered wood product that is sawn to consistent sizes and is virtually free from warping and splitting.
