<br /> Grade Options and Product Benefits Application Examples
<br /> Weyerhaeuser's line of truss products includes several grades of performance tested Example 1: /�- •r�M
<br /> MEL and MSR lumber,plus a unique grade of Microllani®LVL produced specifically for an M-12,1650f,1800f, .
<br /> plated-truss applications. or 2400f
<br /> • M-12 is our newest performance tested MEL product.Made from Southern Pine,it's
<br /> designed to meet the requirements of most truss applications.
<br /> • 1650f and 21001 MSR SPF lumber and 1800f and 2400f MSR pFLN lumber come in Example 2:
<br /> 2x4 and 2x6 depths,making them versatile,multi-purpose truss chord products, M12,1650f,or 2400f webs
<br /> , ir2::: ,
<br /> The 1650f SP product is available in 2x4 depth only. and top chards;2100f,2400f,
<br /> or M-23'bottom chord
<br /> • M-23 MEL SP lumber provides more strength than M-12 and is available in deeper
<br /> nominal sizes.It performs well in high-road applications,and when limited
<br /> deflection is critical or a reduced cross section is desired.
<br /> • 2400f lumber is our strongest Southern Pine MSR product and is available in Example 3:
<br /> deeper nominal sizes.It performs well in high-load applications,and when limited All M-12,1650f,
<br /> deflection is critical ora reduced cross section is desired. 1800f,or 1400E
<br /> a 2,0E Microllam®LVI.Grade is our premium chord product,designed for plate
<br /> connected truss applications that require high-stress members—such as bottom Example 4
<br /> chords in girder trusses,bonus room trusses,or top chords in tail-bearing trusses. M12,1650f,1800E or 2400f

<br /> MEL and MSR benefits: 2100f,M-23,2400f.orb
<br /> ■ Both MEL and MSR lumber grades contain less wane than industry standards, bottom
<br /> a hord 1 ®
<br /> providing a superior plating surface and an appealing appearance while also bottom chord
<br /> reducing material waste.
<br /> ■The consistent strength of MEL and MSR lumber—something you can't count on
<br /> with visually graded lumber—means trusses will deflect similarly under load,
<br /> resulting in smoother ceilings and ridgelines.
