rsj

We are in the process of having the chimney removed. So the builders have just put in two RSJs (152x152x23-5350mm). They sit on engineering bricks and steel plates at both ends. One end was chamfered to fit the roofline. The RSJs sit on 10mm steel plates at the roof side and 15mm plates at the...

Hi all I have started drilling into the wall above our French doors downstairs to try and fit a curtain pole, and appear to have hit an I-Beam/RSJ. No idea when it was installed - the house is early 1900s, so any time after then. At this juncture, I’m wondering what the risks are of me...

Guys - hoping someone can provide some advice on an issue spotted whilst completing a garage conversion. 3 years ago a previous builder cut a door space into an internal wall. At the time, i had no reason to question it. I recently contracted another builder to complete the work - he mentioned...

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.

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...

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...
