WebAug 1, 2024 · Compression test specimens of nominal dimensions: 14 mm (tangential) × 7 mm (longitudinal) × one complete annual ring with one more latewood section (radial) … The machine grading process sorts dimension lumber by strength and stiffness to improve consistency. The table below shows four common MSR grades and design … See more MSR lumber simplifies many design considerations because a grade such as 1650f-1.5E maintains the same Fb, Ft, Fc, and E values regardless of the species or size considered. Other properties, however, change by … See more
