While there are 46 total grades of MSR and MEL, only a handful of these grades are currently produced by sawmills. The MSR Lumber Producers Council compiles a handy survey each year which identifies volumes produced by species, size, and grade. The most common MSR grades are 1650f-1.5E, 2100f-1.8E and 2400f-2.0E. Calling local lumber suppliers will identify the grades available in local markets. Below are U.S. and Canadian design values for popular grades of MSR and MEL.
