beams and headers
This Technical Resource Sheet is a supplement to the Trus Joist® Beams, Headers and Columns Specifier's Guide, TJ-9000.
Please refer to TJ-9000 for additional design, construction, and product handling information for Microllam® LVL beams and headers.
Trus Joist® 2.0E Microllam® LVL
Weyerhaeuser is pleased to announce the availability of 2.0E Microllam® LVL.
During the design process, many factors are considered when determining
the size of a beam. Modulus of elasticity — commonly referred to as beam
stiffness — plays a very important role when it comes to achieving maximum
member span and an efficient, cost-effective design.
Market Availability
2.0E grade Microllam® LVL will soon be available in all U.S.
­markets. Consult with your local Weyerhaeuser representative
for timing.
Available Sizes
Widths: 1¾"
Depths: 5½", 7¼", 9¼", 9½", 11¼", 11⅞", 14", 16", 18", 20", 22"
and 24".

(1) Unless otherwise noted, adjustment to the design stresses for duration of load
are permitted in accordance with the applicable code
(2) For lateral connection design, use an equivalent specific gravity of 0.50

(4) For 12" depth. For other depths, multiply Fb by d
(5) Ft has been adjusted to reflect the volume effects for most standard applications
(6) Fc⊥ must not be increased for duration of load
