Loft steel undersized?

[Leofric]

Thanks for the reply, much appreciated. In regards to tighting up the HSFG bolts, how tight should you get them? is there a special tool that allows you to set the torque?

Also one more question, in regards to the padstones for these beams, I was looking to use steel plates instead of padstones due to thesize specified by my SE which were250x10x215. This would mean going below ceiling level in the bedroom below which we want to avoid.

Are steel plates as an alternative to padstones as effective? I was think of using steel plates that are 450 wide, and 100mm, 30mm thick and 100mm wide.
