Most wood structures are of a redundant nature, with the load forces distributed among multiple components. This results in more of the load being applied to fewer components which reduces the overall rigidity of the structure and reduces reliability. Better uniformity between suppliers. Because MSR lumber uses a consistent rating system throughout the industry, an end user can work with multiple suppliers without worrying about compromising lumber quality. An MSR grade is produced to the same quality standard by all the producers.
End users can therefore shop for the best price from a number of suppliers.
Ability to substitute species. MSR grades can be produced from a multitude of wood species from a number of different sources. A grade produced from Spruce Pine Fir in Canada can also be produced from a Western or Southern species Lumber design values for MSR grades are more species independent than design values for visual grades. This means that the end user may switch to a less expensive supply without worrying about compromising quality. Savings for distributors.
