For sale structural steelwork for shed 78ft9in (5 bay) x 40ft x 14 ft eaves
4 No. gable posts
4 No. wind bracing roof bars
Steelwork 8x5
Gable posts 7x4
All steelwork shotblasted and painted
4300 sterling plus vat

Now I am actually going to go back to him and ask for the shed to be 16ft to eaves so price will go up a fraction. But more so than the importance of price, I am wondering what do ye think of the metal size for this size shed? Is it adequate? Anything further I need to check. Where I live can get windy at times.

How much more for bigger main stanchon girders and Galvanized?

Steel on small side. In any case you need structural calcs doing for your postcode What may be ok one place won’t be another

Increasing my height by 2' on 12 uprights cost me £200 about 9 months ago. I believe steel has gone up since.

If the section on the uprights is on the light side they may need enlarging for the extra height.

I.m no expert but it looks light enough steel to me and if you go higher (which is sensible imo) it would require heavier steel I think

We are currently on with a building pretty much matching these dimensions, same span anyhow. I've calculated 254mmx146mm or 10x6ish and I'm still thinking of going the next size up to 305x165 to future proof and make the building stronger than it needs to be. Steel is the cheaper part of the job...

So I'd be thinking you'd need bigger steels than quoted but like others have posted, you really need a survey based on your location, wind direction, elevations etc, all need to be calculated to spec the correct steel sizes.

Yes good advice. For £200...£300 he could have all calcs and steel sizes worked out for his location to CE standard
He’ll not get insurance without it

8x5 seems light for a 40 foot span. 10 would be nearer the mark
