An engineered structural wood product finished on 4 sides is known as?

• A. LBL I beam
• B. laminated strand beam
• C. architectural grade beam
• D. laminated veneer lumber beam

Answer: (C)

Architectural-grade beams are designed to be finished on all four faces (S4S), making them suitable for exposed use where appearance matters. This four-sided finishing provides a smooth, uniform surface on every side, ensuring consistent staining or painting and a clean look from any angle. In engineered wood, the term architectural grade signals not just the material, but that the beam commits to higher surface quality and defect control for visible structural elements. The other product names describe the beam’s type or construction (such as I-beams made from laminated veneer lumber or laminated strand lumber) but do not inherently denote four-sides finishing. So when the criterion is being finished on four sides, architectural-grade beam is the best match.
