Open web joists in UK
(OP)
Guys,
Are open web joists used in the UK? we have a project in Dubai and we are trying to use DLH joists for a roof framing, however, during a meeting with a local steel supplier, it seemed that they are not used to such trusses.
Can anyone give me more information regarding the use of joists and joist girders in UK?
Thanks

You can call a caastellated beam a verendreel (dont think I spelt that right) truss because technically it has no cross members.
In the UK I dont know the last time I specified a castellated beam, we generally use a cellform or cellular beam. I understand from a chat with a westok representative that they cut the beams to be holes instead of hexagonal shapes because there is less material waste.
If you mean a joist - as in it has tapered edges on its flanges and the flange thins from web to tip then we dont really use "joists" at all as they are incredably weak.
Also why are you asking for UK information when the project is in Dubai? Are you going to export the beams to Dubai from the UK?
If you need any information on light trusses call metsec, or if you need any on cellbeams give westok a call. Both are very helpful.

Based on a meeting with a big local fabricator, the steel sections etc are imported from outside Dubai. BS5950 is the code of choice and hence all sections have to be British sections. I am surprised that this is the case as ACI, ASCE and UBC are used extensively.
