Instead of beams and girders, you may wind up using decking and joists instead. LVL offer several advantages over technical milled lumber, it is made in factory under control specification and it is more stronger straighter and more uniform in size. Regardless of what material is specified, there needs to be adequate stiffness, strength, and shear resistance. Such was a recent experience when I was looking for a beam for a renovation project. UMass Amherst | Department of Environmental Conservation, Home / Publications / Articles / Sizing Engineered Beams and Headers. Differences (5) Most mills, however, employ a continuous press line. Totally the load for that wall will be twice as much as whatever the load would be for buildings that have a center wall.
