LVL’s very high tension parallel to grain strength makes it ideally suited as an outermost tension lamination for glulam. LVL has better mechanical properties and dimensional stability than sawn lumber. And, because it is manufactured in long lengths, it is not necessary to introduce an end joint into these laminations. This eliminates one of the key variables controlling the strength of conventional glulams. Design properties of 30F-2.1E means that GL3000 has an allowable bending stress of 3000 psi, which is 24% higher than conventional glulam, and a modulus of elasticity of 2,100,000 psi or about 17% higher than traditional glulam.
