Hi all
Could anyone please advise.
I am planning to change my conservatory to a single storey extension,it will be 7mtrs wide(width of house) x 3mtrs depth with a 30 degree pitched roof from the house using concrete roof tiles.We intend to have a bi-fold door set installed which are 4.5mtrs wide.Can I use a heavy duty steel lintel (Catnic,IG) above the door set or should it be a steel beam.
Any help would be greatly appreciated
