what would the steel sizes be for a 100ft wide shed be? Thanks
Hi,
For shed of that size I would advise use 533 x 210 x 82kg Posts and 457 x 191 x 67kg Rafters if up to 16 foot to eaves really.
If you do require a quotation please send me details and I would be more than happy to send you a quotation out.
Many Thanks
Kind Regards

Roof pitch ,roof materials ,location ,bay crs ,height to eaves, use of building and details of side cladding and doors all information you will need to make a calculation on steel sizes. The one we will be erecting tomorrow 83 ft span 21 ft bays posts 457x191x89 rafters 457x191x67,100ft span 406x178x64 rafters ,posts 533x210x82 if less than 16ft eaves
@Agri Design I had covered that one by asking the "location" your right sorting out all these details could save quite a lot of money on a big shed if it happens to be in a favourable location , i have seen a farm building with 20" of snow on the roof ,it does make you thinkGlad its not only me that post a list of questions as a reply. I would add it also depends where in the country it is as the wind - snow loading differs. All shed should now be CE certified which should force shed suppliers to take all these points into account at the quote - initial design stage.

in that case can you do a span and lean toosCheers for the replies. Was just trying to gage the sizes needed, to see if what I was thinking on was even feasible without wasting anyone's time getting a quote. Made me realise that it's not a job to be bodged up as such and will need a designs done.
For sheds that width would there be any benefit in using posts to support the trusses if possible to reduce size of the steels or would any saving be minimal.

I have seen a number of your posts. I work on behalf of a number of contractors throughout the UK who supply and erect agricultural structures. I am a member of this forum in a personnel capacity.
It appears to me that your are posting, as some others do, in contravention of the forum rules in that you are advertising the company Graham Heath Construction Ltd.
I joined this forum earlier in the year. My intention was to inform an advise the Farming Community on a pro bono basis with impartiality.
As you are promoting the company you represent in contravention of the rules perhaps you could enlighten us all to the deflection limits your Engineers and thus Graham Heath Construction Ltd are applying to the structures you supply. This, I my view would be beneficial to all, particularly if you can confirm that you are working within the Steel Construction Institute Guidelines. In particular I am interested to know what are; the eaves horizontal deflections limits, the apex deflection limits relative to the gable and the purlin deflection limits.
I’m sure that your company will have this information readily at hand. I’m also sure that as a reputable company you will embrace my view that we should provide accurate information which will enable the Farming community to make informed commercial decisions.
To all: Engineers design to basic criteria. The first is safety –this means it won’t fall down and kill people. The second is serviceability – this means that the building should not be so flexible that it jambs the doors for example and voids the warranty on the cladding – when the frame flexes it over stresses the cladding fixings, ovals the fixing holes and causes leaks in the roof.
The new amended BS 5502 Agricultural directly refers to the Eurocode and buried in the code is a statement that deflection limits should be agreed with the client ie the Farmer! If this is not explained to the Farmer who is a client just like any other client what then?
This was not made clear in the guidance issued to all Farmers following the major storms earlier in this century ie after 2000
