loft floor steelwork
 

You know there's always a crane, holes in roof etc. to get loft floor
steelwork in.
Any reason why the RSJs etc couldn't be supplied in 2 pieces with great
big metal plates to
bolt them together ? Then I could carry the bits up there myself ! May
be cheaper than a crane.
I plan to do a structural loft floor, then a dormer conversion later.
Cheers,
Simon.

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.

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.

May be cheaper than a crane.

Cranes are actually rather good value.

I plan to do a structural loft floor, then a dormer conversion later.

Hi, i converted my loft 15years ago,i had my rsj cut in half and then

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 to increase in order to conteract the moment induced in the beam. Stick a joint at mid-span and you are asking for trouble with a splice plate as the beams capacity is suddenly transfered to the bolts capacity to not shear/fail in bending. Welding is good, but again unless you do it yourself, up goes the price.
