Steel rather than Timber

[Triassic]

When I had the structural calculations done for the balcony the structural engineer specified timber rather than steel.

 

If I now want to use steel rather than timber, do I need to redo the structural calculations, or is there some sort equivalences chart for steel versus timber?

 

In normal circumstances I'd ask the structural engineer, however he retired during Covid and his web site and email no longer work.

Why steel...its sky high price at the moment. I just recently swapped steel to KERTO beams in build as steel was £1100 and 2 x 220 x 90 x 5350 Keto beams £150.

To answer your question, structural calcs would need to be redone

@gravelrash Do you have a link to Keto beams?

 

Ah just realised you mean Kerto!     All I got searching Keto was beans!

Mainly because the balcony is 2.5m wide and 16m long with 20mm glazing the three sides. I was'nt sure if timber was the way to go?

that's a room...?
