Hi,
Every house I have ever owned has had a steel I beam supporting the floor. Why not a GlueLam if it strong enough? Seems to me that it would be easier to work with as far as other framing. Any comments?
Thanks, Walt

Steek, Glulams, or simply laminated 2x10s or 2x12s glued, screwed and laminated can and will meet minimum deflection rates for loads in question.

What this means is that you can have several different types of materials give you the same load bearing factor.

The problem is that each factor has a different cost and use.

Although steel can give the best overall bang for the buck, steel has it drawbacks.

Given a fire, steel performs abysmally compared to structural lumber or even OSB.


Lot more to this equation than meets the initial eye.

Steel is usually the least expensive option for long spans and generally uses up less headroom but connecting to it can take extra labor.

Other options include LVLs and flitchplate assenblies or short span beams on posts.
An engineer will weigh the options and the cost.
