Galvanized steel purlins are they easy to get.

Hugh 2

Aspiring to building a shed to house new bulk tank over Christmas and new-year
To make the roof simpler I am looking for purlins that need to be 20 foot.

Are galvanized ones easy to get in a hardware or are they more specialised ?

Hope to get them tomorrow to have shed weather proofed by first few days of January.

Hope to use insulated sandwich sheeting for roof (Might need to use Google to find out what these are called).

I am in Co. Waterford

Thanks

I'm sure any good roofing place would get them for you.

On the Z purlins search donedeal for "purlins" and you will get some results.
Don't imagine you can get them everywhere.

The insulated cladding is dear. Its just called "insulated cladding" as far as I know.
I got the insulated cladding from skyclad (dot) ie/cladding (dot) html
Its cheaper than the kingspan stuff, as the insulation is the white aeroboard type.
It has a nice white inside metal skin which would be ideal for over the bulk tank.
(outside layer of ordinary cladding - sandwich of insulation - inside thin white metal skin)

If you do go with the insulated cladding, make sure you fix it in the ridges (high part) of the cladding. NOT in the valleys as in the image you posted!
If you secure it in the valleys with insulated cladding, it will deform and make a dent/indentation where water can get in (speaking from experience!)
(With ordinary cladding, you fix it in the valleys, as the valleys are directly supported on the purlin).

Z or C ? Do they have different lengths?

Cloke brothers out in caim can get you anything you need or Kellys in borrow

Why do you need a 20ft span? Could you go 15ft and use timber?

It will be over bulk tank and looking for clean finisin the old dairy we had to sheet over timber ceiling to pass coop criteria on washable surfaces

New building will have 20 gables and steel would span it in one go ( that's the theory anyway )

The exercise is turning academic as the bigger hardwares are closed till January 4 or 5

How many are you looking for what height and what load might be in force.

On normal roof claddy you also only fix on the ridge. Its doing side sheeting you fix in the valley. Otherwise you will have water getting in through your roof

Suir Roofing near Carrick on Suir might be worth a call.

Most dairy's around here have just got timber beams and purlines, all painted and that seems to be good enough

If metal purlins turn out to be cost prohibitive I might consider timber (painted before putting up) but when going to the effort to build new tank house I will try to have things looking nice.

6 maybe 8

Load and force?

6 purloins should be enough and 8 might be over spec

20ft purloins will cost 50 euro each at 150mm height, you need to put a stay on every second one as support
Really never needed but if you get a 3ft snow fall the weight ofthe snow cut cause the purloin to buckle.
Spacing should be no more than 1250 between them

I have 20ft Purlin, available at €37.50 each incl vat

Thanks.
I have the purlins up at this stage
I went for 7 meter ones so as not to cut insulated sheeting that was going on them.
As I got the whole roof gutters and all delivered in one load I am not sure what I ended up paying for the multi beam purlins .
Blockwork was slow over Christmas /new year - last blocks and purlins went up Sunday and just have to wait for things to dry out before putting up sheeting.
