rsj

I need to move a 6.6 meter RSJ @ 97Kg per meter. For clarity - I cannot use a crane due to overhead wires, I know that I can list with genie lifts latter My plan is to move it from my uneven drive using 3-inch fence posts using a hand winch (rated at 4 ton) to pull it onto the block and beam...

I’ve had some major renovation on our house with large RSJs being installed, among other things. The builders’ left and I’m now getting on with the improvements/repairs I can make myself. One of the jobs is replacing the floorboards they’d ‘fixed’ using smaller metric boards with the correct...

Hi all, I’ve recently had some major renovation on our house with a number of walls removed and RSJs installed on the lower ground floor. The builders have now gone and building control signed off the work. There’s still a lot to be done, however. I need to fix some rotten joists by the front...

As per title really - is it ok to hang joists on a joist which is already supported at either end on joist hangers? I'm looking to get rid of the ugly timbers which are below ceiling level under a flat roof which is part of an extension from many years ago (1980's). It's a bungalow and the...

Hi, Just after some thoughts on Rsj sizes for a flat garage roof Garage is new built single skin 6.5m x 6.5m and its got 2 pillars on the left wall and 2 pillars on the right wall evenly spaced out @ 1/3rd & 2/3rds of the way, So will need 2 Rsj's to support 6"x2" joists (400 centers) with 18mm...

Hi - I am feeling a bit lost and would love some advice! I had French doors put in place of a window on my first floor about 2 years ago. There had previously been a window of this size in place as the brickwork was different (although a much smaller one was in place when I moved in) so the...

Hi, I’m installing a 4m 152*152 23 rsj in a double skinned internal wall with no cavity. Both sides internal as it used to separate the garage. This is a bungalow so only has a triangle of brick above it which supports purlin. Because of existing lintel when I put the padstones in the steel...

Hi, I understand the need for calculations but also understand the difficulties when the lintel is cast in place? I would like to remove the single brick partition to the left. This is the old pantry. The lintle is holding the side of the house (3 bed semi detached) the pantry is part of a flat...

Very soon we are intending on creating an open plan kitchen/diner by holding up the gable end of the house using "picture frame" type steels. The calculations mention considering to use scaffolding/racking shores? Are these necessary? We were intending on using plenty of Strongboy XLs (on a...

Hi I have a single storey extension going in with a 4m long bifold to the garden, it is likely that due to this span we would be installing this steel with welded plate as you’ve shown in your detail drawing. My question is: Where this steel is supported at either side of the bifold, will the...

Ok, guys here is quite a specific question and know I maybe should get an engineer to calculate my steel, however, thought would try as there is there some great help & info available here. What we are trying to achieve is to take most of the back of the house, to extend our kitchen. Looking...

Hey, We are investigating the possibility of removing 3 internal walls (sections of walls) to make 3 small rooms into one large room. One 6.5 meters, Holding up floor joists and stud walls One 3.5 meters, No joists but a “vertical beam” that is under a roof purlin One 1.5 meters, Holding up a...

Hi, I am having an extension and have 2 parallel rsj ( one for inner wall and one for outer wall ) with a 100 cm gap in between. I want to leave the beams exposed as I have designed the kitchen around this idea. What can I use in-between the beams so when I paint them they look like one beam...

Recently had an rsj installed as dinning wall has been removed. Rsj sits on internal skin on a pass time, but only has 80mm bearing on each side? Will this be okay?? Thanks in advance

Hi All We are in the process of self building a single storey extension on the rear of our property. We are aware we need a steel ridge beam for our gable roof and have had calcs agreed by building control for this. 152x89x16 at 4.2m being deemed sufficient. Situated approx 750mm Below each...

Hi guys, was wondering whether anyone could offer some advise regarding RSJs that our builder has installed. The job was done at breakneck speed and as a result the RSJs weren't level which I challenged builder over. Subsequently, they've decided to try lowering them by 10mm to get them level...

I've had a set of bi-folds installed which required a 5m RSj to be installed too. The RSJ has been installed onto two pieces of cut steel and not padstones due to my exposed brick outer wall. The RSJ over it's length has in excess of 10mm difference in install height and the RSJ is not level...

I'm nocking though into what was an old outside toilet, the two are separated by a solid brick wall. Sent this info off to an SE to get the steel specified and they came back with 178 x 102 mm UB. It's cranked, so a bit more complicated than the standard. Do you think they missed that it was a...

Please can anyone give advice on this rsj installation. I think we might have issues with building control on this one. The joist hangers haven’t been put on correctly and have been cut off instead of bent over the top. Is this safe and will it pass building control inspection? Thanks

The outside of my unusual conservatory needs finishing. Above the doors is a 152 mm steel beam (approx. 4.3 m), which has the grey factory coating. On top of the steel are aluminium window frames - with no sill - in RAL 7016. They are only a few mm behind the front of the flange of the steel...
