loft floor steelwork

Some loft conversion companies do choose to do this, but when you take the cost of fabricating the beam splices and the labour of assembling them it probably end up costing more. Of course in some places overhead cables and/or trees makes craning in beams impossible.

Yep. WIth me doing the labour, I wonder how the price works out. I suppose the cost of drilling etc, may make up the difference. Simon.

No reason at all - they often are. But of course cost more. They have to be 'spliced' at the suppliers.

I somehow doubt it. Steels are heavy.

Cranes are actually rather good value.

Hi, i converted my loft 15years ago,i had my rsj cut in half and then welded them in situ taking great care,i am a skilled welder,it is possible. Good luck. Paul

It can be done, the Strutrial Engineer needs to design the steels with the joins you propose.

And the cost of the steel suddenly goes up :-(

It depends where the joint is as to whether the steel size needs t increase in order to conteract the moment induced in the beam. Stick joint at mid-span and you are asking for trouble with a splice plate a the beams capacity is suddenly transfered to the bolts capacity to no shear/fail in bending. Welding is good, but again unless you do i yourself, up goes the price
