Engineered Lumber

Start with the job the member performs: beams and headers, or floor and roof joists. Compare the exact product series and the documents for your region.

Before choosing your setup

  • Identify the product family, grade, series, and member dimensions specified for the project.
  • Check that the manufacturer guide covers your region and exact product.
  • Keep structural sizing, connections, and modifications tied to the project design and manufacturer documents.
