203 x 203 uc steel

[Ashworth1]

Hi I have just had my calculations/ drawings back from my SE. Above the by fold door he has put to fit a 203x203 x 60kg uc with 300x12mm plate welded to bottom flange. This was only drawn to be fitted on the inner leaf. A universal beam will be supported from this uc but my question is what about the outer leaf?

Cavity wall? Normally the beam will sit on the inner skin with the flange on bottom taking the outer skin. Not much info tbh?

Is the plate on the bottom intended to support an outer skin of brickwork, perhaps?
That's usually the case if he's shown the beam on the inner skin.
Quite a hefty beam - what's the span?

A 203mm beam can not sit on just a 100mm wall. The welded plate is a spreader to load both skins of the cavity wall

Beam that size must be about 8m!

Hi thanks guys. It's 4600 but building above it and taking another steel off this beam. All makes sense now.
Is it possible once the beam is fitted to drop the height underneath as I am looking into bi fold doors and the max height is around 2500. This is borderline where the bottom of the beam will fit- there might be another 50/100 mm. Is there a way of dropping this height, bearing in mind It will be internal/external. Outside to be peppble dashed. Cheers

How would you drop the height once the beam is fitted?

I am assuming that the bottom of the beam will be sitting at plate height. So from my floor to the bottom of the beam will be over 2500mm. Is there anything that can be fitted under the beam to make up space ?

Why can't you put the beam in at frame height?
