Laminate Beams

What is the difference between micro-lam, glulam, and LVL beams? If there is a difference, which type is the strongest?

Thanks in advance,

A mico-lam is a small scale Glu-Lam which is several boards laminated together to form a much stronger timber. A glu-lam can be fabricated in arches and curves and can be exposed to the weather. Glu-lams are typically found in modern churches and small arenas.

An LVL, laminated veneer lumber, are thin vertical sheets joined together resembling plywood, however the laminations are all parallel. Not as strong as a glu-lam, but still stronger than sawn lumber LSL (laminated strand lumber).

If aesthetics is not a problem, than Parallel Strand Lumber (Parallam) is a good choice. It is fabricated from parallel strands of material with more adhesives.
