steel or laminated timber beam?
Hi
I am having a 6 panelled stacking sliding door installed with a panel of louvres at each end. The total length of the doors/window will be 6.2m and 2.1m high. The actual opening space is around 3.75m. (Louvres FXXXXXF Louvres) I have had quotes from 2 builders. Builder #1 suggested a steel support beam 300m high with steel support posts at either end. Builder #2 has suggested 2 laminated timber beams 240mm deep, 45mm thick, nailed together with no additional support posts. Obviously the timber option is cheaper, requiring less labour to install. My questions are which option is structurally the best? and which would you opt for?
Thanks!
