steel beam

Sorry if this is a very obvious answer however I cannot find it in the archives or on Google. When fitting timber joists to steel. If I opt to notch the timber into the beam what stops it from falling out. On all the guides I’ve seen they are just plonked in the web with noggins and wall ties...

Hi all, Looking for some advice, please. I'm in the process of buying a house whilst going through the checks I noticed a pending building application from 2016. Long story short, the sellers had an internal supporting wall taken out to open up the cellar and create a large kitchen area. The...

Hi, We had a structural engineer visit and tell us the wall we wanted removed was load baring. It was a 3m wall between kitchen and dining room, front to back, parallel with joists. He said it was supporting the timber frame wall above (2.2m in length, directly above) and a joist sitting...

Please could I have an idea of what I should expect to pay for the supply and fit of: - 152x152x30 steel beam 9m span, or spliced in 3 with 200x120x10 end plates - 400x155x12 flange plates bolted to the steel - padstones either either end 330x140 - a single SHS support column 100x100x5 -...

Hi All, I have a first floor extension similar to the one in the photo below, but about half the span (~3.3m span with two columns). The photo shows that they used a steel beam with a plate welded to the underside, but installed the beam to carry the outer leaf rather than the inner one...

Anyone know what size and style lintel to go in a 3M wall where the patio door is 2.1M? Previously a window and block

Hi Currently have a builder doing an extension on my home and it requires a 305 steel being installed on posts. My aim/instruction was to 'hide' the beam but putting it higher in the property and the floor joists will then run into it. We have a 305mm steel beam but the cavity wall is 1980s...

Hi, just looking for some advice on something. I’m getting a sunroom/extension built at the back of my house and noticed the builders are using 120 mm thick Kingspan floor insulation boards (TP10/TF70/TW55) whilst the Architect’s Outline Specification states that it should be 150 mm thick...

Hi, I'm having a vaulted ceiling and a Ridge Steel has been fitted. Internally, I want a triangular ceiling. I was wondering how the rafters should be fitted on the steel. I've attached an image with two options. 1. where the rafter fits into web of steel with noggins 2. add a bolted timber...

Hi All, Can somebody help me? I am doing an extension rear single storey, side double storey 7.6X3.5m front single storey on a semi. My question is about a double-storey wall. On left side I got an old wall (existing) backside steel sitting on the goalpost, first floor wall I can build on...

We're looking to remove a load bearing wall, which is supporting one wall of a gabel, the floor above, ceiling above and roof above. I've sent our structural engineers calcs to my dad and we're both a bit concerned. The above image shows the wall (and chimney to be removed). The wall is...

No longer required thank you for replies

Hi Guys, i have a small lean-to outbuilding that currently has a door and a window next to each other, i want to enlarge the opening and use it as a garage. this would mean removing a central block column that is helping to support the rafters. Im trying to ascertain what size of steel to...

Hi Guys, Just wanting some advice on a loft chimney breast support. At this moment in time i haven't actually gone into the loft to measure it, but the breast runs down of course from the roof, loft, into bedroom 1 and the living room. The idea is to take it out of the bedroom to allow for...

Hi all, I am in the process of completing on a ground floor flat and wanted to do a rear and side return extension, but wanted to clarify some things before drawing up some plans for planning permission. The extension I have in mind would require the corner of the building demolished and...

My wonderful builder left me with this mess after not quite finishing my extension. This is the bathroom above the kitchen where an RSJ ended up encroaching into the room at floor level. I want to tackle the puzzle of fireboarding it myself, but am not quite sure on what needs to be done to...

We are considering replacing a bearer supporting one side of a bedroom floor. Yes I know that we will have to engage a structural engineer for formal calculations etc., but for now, I just want to get an idea of practicalities, sizes etc.. A builder has suggested using hollow rectangular steel...

Hi there, I am doing a loft conversion on a terraced house. Both neighbours have already done loft conversions (unfortunately). I say unfortunately as I believe this just makes my loft conversion slightly more complicated with regards to waterproofing and joining to their structures. Nither...

Without getting into complex engineering calculations, how can I make a reasonable assessment of the max compression load for an approx 2 M length of mild steel single angle 7mm thick and 80 mm each side. I would like to use it as a mid span "post" to give additional support to what appears to...

Hi everyone, I'm in the process of starting out with an extension to our property that will involve knocking through the rear wall, with the intent on creating a large open kitchen/diner/living area. Architect is on with the plans now, and we'll be getting an SE in to calculate steel...
