<br /> Grade Options and Product Benefits Application Examples
<br /> Weyerhaeuser's line of truss products includes several grades of performance tested Example 1:
<br /> MEL and MSR lumber,plus a unique grade of Microllam®LVL produced specifically for All M-12,1650f,18001,
<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 2100f MSR SPF lumber and 1800f and 2400f MSR DFLN lumber come in Example 2:
<br /> 2x4 and 2x6 depths,making them versatile,multi-purpose truss chord products. M12,1650f,or 2400f webs �!
<br /> The 1650f SP product is available in 2x4 depth only. and top chords;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-load 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 or a reduced cross section is desired. 1800f,or 2400f
<br /> ■ 2.0E Microllam®LVL 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,1800f,or 2400f
<br /> MEL and MSR benefits: 21001,and 23,chords;, r80�'
<br /> • Both MEL and MSR lumber grades contain less wane than industry standards, Microllam®LVL
<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.
<br /> 2.0E Microllam®LVL manufacturing benefits: Examples Bonus Boom
<br /> M-12,1650f,1800f,
<br /> ■ Fewer plies are required in most girder assemblies. or 2400f webs and top
<br /> • Chords resists shrinking and splitting. or Micrhords;M23,®LVL
<br /> or Microllam LVL
<br /> ■ Standard depths(up to 14')match depths of adjoining floor systems;longer bottom chord
<br /> lengths(up to 60')reduce the need for chord splicing.
<br /> Note:To ensure appropriate specification and design,Microllam*LVL can be used
<br /> only by authorized truss manufacturers who use truss design software by the
<br /> following companies:ITW Building Components(Alpine Engineered Products and Wer�lfFh�rrrlIR/umrandZOELK
