I’ve attached a drawing to show the existing, temporary and final diagrams to help show the question. The structural engineer has designed our loft with 2 floor steels and a ridge steel. The installation of the first floor steel (beam A) is simple, as nothing needs to be removed to install it...

Needing some advice. I'm. In Scotland and we got plans and drawings etc to knock a load bearing wall down and put up Rsj, got all the permissions, structural e gineers sizing and all that. Had loads of problems with the job, loads, turns out the wall wasn't made of brick it was poured concrete...

We are planning an extension that will abut to our pitched roof. This will involve cutting back rafters and replacing the roof plate with an I-Beam. I would like to understand how this should be installed to continue to support existing rafters please. The below shows 2 options of how I envisage...

Hi, I’ve a 4M sliding door with a universal steel beam above it and I’m trying to hang curtains by drilling into the underside of the steel and affixing the mountings. I’ve bought HSS drip bits (dewalt) and self drilling (not self tapping) screws (4.2mm x 50mm). Nothing seems to work. This is a...

Hi folks, I'm ripping out two sets of old patio doors to be replaced next week with aluminium bifolds. The RSJ across the top of the apeture has been rendered externally in a way which doesn't match the style of the rest of the house. I've realised there might be an opportunity to fix this...

Hello, today I've seen some patches on plasterboards and it was getting wet without any leakage. Upon further investigation, condensation on steel beems were seen.. before plastering it over, please can someone recommend what it needs to be done? (Appreciate if you can give me a name or link to...

Hi All, New to the forum so apologies if that has been covered in an earlier post, but I couldn’t find anything! I have a 2 storey Victorian built house and I’m looking to move the doorway to our lounge more towards the centre of the room. But my problem is, there is an RSJ around 3.4m long...

We've been having a Dorma loft conversion done, the build included the need for 5 RSJ's. One of the main issues we had been facing was freshly plastered ceilings cracking on the 1st floor, which effectively were directly below 3 of the 5 RSJ's. I decided to rip the ceilings down, I found that...

Hi all, hoping someone can help with some concern I have with a wall in our flat roof garage. There are cracks in the brickwork where the previous owner looks to have drilled some holes. The issue is there is the door frame and RSJ above which looks like it could collapse. Trying to understand...

Hi, New here. Need some advice on a project I’m working on. Iv had a 5meter RSJ put in across the back of my house. I have some bifolds ready to go in for now but In 6-8 months time I am having an extension. When I do the bifolds will move to the new extension. The problem is the RSJ...

Universal Beam 1.8m length 1.46 opening in single leaf wall. Supporting walls are 350mm and 400mm wide. SE has specified 3 courses of blue bricks rather than a padstone. Do I get the brickie to lay the 3 courses in normal brick pattern, or are they stacked one on top of the other? Given...

Hi, we're doing up a stone house, and have lots of vapour-related potential problems. Today's problem: we have an RSJ across a room, both ends in external stone walls, supporting the first floor joists. We're installing internal insulation (stud etc.) on all external walls, so the RSJ is a cold...

I have the spec of my padstones from my SE - but he has gone AWOL and I am unable to clarify with him what exactly he means. This is a single RSJ, with top plate, that will be supporting an old, standard brick cavity wall (approx. 300mm wide). The structural calcs refer to "Padstone 1 & 2" -...
