“We’ve been using MSR pretty much since day one when SCS was founded in 1987. It’s a crucial element for roof and floor trusses, especially with today’s challenging designs for residential and commercial construction. By using MSR, we reduce the overall fiber required for the design of our products. For example, a top chord on a roof truss might require 2x6 if only #2 is available but that can often be replaced with a 2x4 in MSR. Likewise, floor trusses may require more webs if the chords are #2 but using MSR can allow us to reduce the number of webs and/or the size of the connector plates used.”

“Our lumber purchasing decisions are based on quality, strength and availability, so we choose MSR. With MSR lumber, we know the quality has been certified, and our lumber supplier is the best in the industry.”

John Nicholson, Deltec Homes, Inc.

“Because we can be confident in the higher design values and deflection properties of MSR, we can often use fewer trusses in the floor system as a whole – placing components 19.2 inches on center instead of 16. Less lineal footage of product to install means a lower installed cost, while delivering a high performance floor that doesn’t sacrifice loading capacity.”

“We’re able to stock less inventory, make less culls, and have a final product with a better appearance. The quality that MSR lumber provides is definitely a selling feature.”

Colin Penner, Penn-Truss Mfg. Inc.

“MSR lumber is a raw material that my company has been utilizing for many years.  It is a high quality lumber that allows my product to exceed industry standards giving my company and our customers a high level of confidence in the final manufactured product.”

Jeff from Minnesota

“MSR lumber is the only solution that a component manufacturer has to use in designs with strict engineering criteria.  Every piece we receive, we know it has the strength to perform.  Knowing those design values, MSR lets us get the full use of each piece of lumber.”

“Our designers are always looking to reduce the amount of web lateral bracing required by increasing the lumber grade to our MSR options. Reduced lateral bracing requirements reduce the installed cost and overall amount of lumber needed within a roof system. I think it’s one of the biggest benefits of using MSR lumber.”

“At A1 Roof Truss, we prefer to use MSR whenever we can versus any visual graded lumber. Consistency, quality and having a more scientific means for grading is our primary focus. We appreciate and request MSR products over any visual grade products.”

“We like using MSR because of the consistency and the reliable engineering values it brings us. This and due to the better appearance Lumber Specialties uses MSR in all its truss lumber.”

“We have been utilizing MSR SYP 2x4 through 2x12 and SPF 2x4 & 2x6 in our truss manufacturing process for many years. Several years ago when visually graded SYP experienced a dramatic reduction in its design values, we turned to MSR lumber as a more consistent product with higher structural capacities. These higher design values combined with the variety of available grades has proven to be a very valuable asset for our truss designers. MSR lumber gives our truss designers the ability to use smaller chord sizes, reduce lateral bracing, and achieve higher bearing capacities. Over the years, the number of MSR grades in our inventory has grown as has the percentage of our total lumber volume represented by MSR. As the demand continues to increase for larger structures and heavier wind and snow load capabilities, the use of MSR lumber becomes more of a necessity. Here at Rigidply Rafters, we have found MSR lumber to be a dependable product with a wide variety of uses.”
