The amount of lumber graded by machine stress rating (MSR) has continued to increase since the development of the technology in the early 1960s. Western Wood Products Association (WWPA) has provided procedures for the quality control of specific gravity of MSR lumber grades at mills since 1996. Our MSR (machine stress-rated) dimension lumber offers guaranteed strength and superior straightness, making it ideal for highly demanding engineering ... Machine Stress Rated lumber (MSR) is evaluated by mechanical stress rating equipment. MSR lumber differs from visually graded lumber in that each piece is ... Apr 29, 2021 ... MSR lumber can be assigned higher specified design strengths than visually graded dimension lumber. This information will appear on the MSR grade stamp with an ... 2 x 4 and 2 x 3 in. Lengths 6 to 9 ft. Grade SPS 3 (jointed for vertical use). MSR Lumber. ... MSR grades of lumber are not distributed as 2-parameter Weibulls. Instead, strength properties of grades of lumber must have “pseudo-truncated” distributions.
