I'm considering using Aluminum (I beams or other shapes) instead of Framing Lumber as the material for the floor joists in a residential remodeling job. The finished floor I intend to support with these joists is traditional hardwood and I would be seeking residential code compliance; nothing more demanding than that.
Can anyone point me to authoritative documents that would allow me to compare the strength (pounds per linear foot), and weight of the two different materials in several shapes (I beam or other)?
I'm certain that Aluminum will have higher strength and lower weight than typical Framing Lumber, but I'd like to see specific numbers.
I'm really just looking to try and get a feeling for options (materials and shapes) and to understand the implications of each option.
