Single steel or double steel?

[sparkymartin]

Hi there, I have a structural engineers drawing showing a steel beam spanning a knockthrough for an extension.

When I showed the drawing to the steel fabricator he said that the drawing suggested it was two beams running in parallel. However I had been under the impression that I only needed one beam. It will be sitting on and supporting a solid brick wall approx. 230mm thick.

The beam(s) are noted on the plans as 203uc46 if that helps.

Does this sound like I need a single or double beam?

Do you need more information to answer this?

(Engineer is no on holiday for a couple of weeks so can't go straight back to him)

cheers,
martin

It's a 203mm wide column, so you won't fit two on the wall, so it must be a single beam

That's exactly what i thought. The engineer must have done it last thing on a friday i think!

So a 203 wide beam sounds acceptable for a 230 thick wall?

Aye... the wall will only overhang the beam half an inch each side
