Hi,
Hopeing someone can point me in the right direction. I'm wanting to replace a sliding door with stacker doors and increase the size of the opening from 1.8 to approx. 3.6m. Its an external wall where the dining opens up to the patio.
I want to find out what size beam I will need for the new span. Where do I find the appropriate span tables and how do I read them? What is the process for this situation? Is there a mobile app I can use?
I'l post some pic's up if I can work out how to do it...
Fyi - My house is a 70's brick veneer low set concrete tile roof. As for the roof structure I cannot say at this point in time as I cannot get access without removing tiles.
Appreciate your advice.
