2.0E Microllam LVL Technical Resource Sheet

­ .0E Microllam® lvl
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.
