Putting a large roller shutter door in the end of an Atcost Shed.

[flatlandfarmer]

Got a 45' span Atcost shed we are looking at putting in a 20ft wide x 18ft high roller shutter door in. Has anyone done something similar?
My lines of thinking would be to remove the two concrete end posts and replace with two steel columns, tying into the rafters with a bracket similar but stronger as shown in the photo? Would this be strong enough?
Would bolting these replacement columns down via a large base plate into the concrete floor be sufficient? At the moment the concrete columns are sunk into their own foundations as such.
Any guidance would be appreciated.

Can you not put channel iron down the sides of the concrete posts?

We did exactly that, but from the centre to one side and it was already open.
We put in two channel uprights, on the advice of the folks that we fitting the door. They then welded the runners to that.
It left space at the side for a personnel door.

Think @neilo was doing something similar unless I am guessing wrong

No, not that big. I'm having one put up that's 15' x 15'.

And you expected me to remember the dimensions ...

For a 20 foot door it needs to be insulated which gives it rigidity and strength, from experience we had two ordinary r/s and the wind constantly blew them out of the tracks, if they tell you that wind locks will stop that don’t believe them.
On our new yard we fitted a total of 14 doors all 20 x 20 and all insulated and we have never had one blow out in the wind in 20 years.

I have purchased the doors second hand and they are too wide too fit between the posts by about 3 foot. And I could really do with the extra width of the new doors.

Ah interesting. Like I said on the previous message I have purchased the doors second hand (although like new) so was looking on fitting them. we have insulated panelled doors on other sheds and never had a problem, so this didn't cross my mind. The wind isn't too bad given it's location. Just wanted to do this as cheaply as possible! It never seems to work out that way!

 

[chaffcutter]

Fair enough, just try to get as many wind locks fitted as you can.

I’ve got 7highx6m wide non insulated quite high ground on grain stores in n Scotland never been a probl

 

[britt]

Mine's 20ft non insulated with wind locks and has never blown in in the 30 odd years it's been there. But it's not particularly exposed.

 

[Exfarmer]

My experience was that it was not the wind did the damage , but pikies who found they could drive straight through

 

[tomlad]

Ive had dave put two shutters for me , no issues but only 10 ft wide .
Based N/W .
He'd give advice even if ur too far away.

[neilo]

He’s doing mine too, after a local recommendation. Very knowledgable fella and ‘proper’ way of doing business.

From near Wigan, he’s been to do a site visit (& measuring) in West Wales, will be coming back to fit it once we’re ready, and still at a very reasonable price compared to others.
Travels all over doing doors, even down as far as Cornwall.

 

[tomlad]

Indeed
So much cheaper than previous quote i was suspicious.
In out 2 hrs door done .

I've done a couple of these. New rsj uprights cut out and bolted round the rafters. End plate and bolted to floor. Neither though had existing concrete uprights.
