Hi all, looking for recommendations on who can replace RSJ/wall beam with a longer one because we just both a house and there is a wall left like 1.5m long on the entrance to the extension we want to remove to have more open plan space, this wall been removed 10 years ago by the previous owner but they told as the steel beam don't go all the way the wall only door gap so we want to replace it with long one and remove this 1.5m wall. Thanks in advance
