I am replacing a wooden deck with wrought iron posts and railings. The current beams are 4x8x8, but the wrought iron rails are welded in too close to the beam top for me to remove the beams without cutting them. (The wrought iron was added after the deck was built. I can cut the beams to remove them, no problem, but I won't have room to be able to angle in a replacement 4x8 beam.
- Would it be OK to instead use two 4x4 beams, one on top of the other? It looks like I have enough clearance to slide those into the beam hangers under the iron rails.
- If it is OK to use the two 4x4s, what you you recommend for how I connect the two beams to each other?
- Would I need to handle putting joist hangers onto the stacked beams in a particular way?
Thank you in advance.
