30F V IJC GLULAMS

ROSBORO BIG BEAM 30F

Rosboro Big Beam DF Glulam is the perfect choice for high strength engineered beam and header applications. The full 3½″ and 5½″ widths make it ideal for wall framing while I-joist depths are compatible in EWP floor systems. Because it is a glulam product, Rosboro Big Beam DF is dry, stable, easy to cut, easy to install, and cost effective. Manufactured with a balanced layup of LVL in the top and bottom chords, Big Beam is the go to solution for multi-span applications.

CALVERT GL3000

The GL3000 beam’s LVL top and bottom cord 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.
