All About Lumber Stamps

Lumber stamps are designed to give you a quick, at-a-glance summary of the type of wood you’re looking at. It also proves that each piece of wood has gone through the standardized grading process.

  • Stand & BTR – This means that the wood as standard and better for light framing. While it meets the standards, it could also be considered constructon grade.
  • S-DRY – An S-DRY stamp on your lumber means that the wood met surfaced dry standards and had a moisture level of less than 19%.
  • Triangle – The triangle stamp will tell you the type of wood your lumber was made from. For example, if you see D-FIR inside the triangle, it means that the wood came from a Douglas Fir.
