HI,
I hope this is the right area to post this question, if not I am sorry. I am looking to change the 100 year old wood beam in my basement with a new beam. However there is very little room in the basement to maneuver a new I beam in place. I also considered building a beam out of 2x6 planks but I have been thinking there may be something better. What I would really like is a beam that is made from composite materials such as carbon fiber. Since the span is 20 feet and a jack post would be required at 10 feet if I use steel or wood, I was looking for a two section beam, both 10 feet in length with the jack post supporting both where they meet. If there are made from composite materials then the beams would be less labour intensive to put in place.
I was also wondering if it is possible to build a beam the doesn't have the top on it. This probably doesn't work but if it does then I can cut what ever inches are necessary into the girders and recess the beam with the girders sitting on the bottom lip of the beam. This would also give enough clearance to finish my basement as the only object that I end up hitting my head is the beam and I wouldn't have to dig out the basement more.
Do such building materials exist? I have been googling for some time now but no luck.
Thanks,
Carl
