MDPE polytunnel

[Blueberri]

Hi all
I am thinking of building a 6mx3m polytunnel using 26mm galvanized steel tubes and 32mm MDPE pipe, do you think this would be strong enough to stand up to our glorious UK weather if I used batons as bracing or should I look at getting thicker MDPE pipe?
Thanks

Think youd be better off with the thicker stuff

I bought a ready made frame that size off Ebay - didn't cost that much and I'm well known for being mean ( bought the polythene separately though)

I am picking up a 16foot trampoline this weekend, and I am planning to take that apart and build a poly tunnel with that. Hopefully I will find one more, to allow for four half-moons

I would advise using heat tape to protect the plastic, even if you're using plastic pipe for the structure.

I'd also advise to buy a big cover, so you can bury it all around, to hold the whole thing down and keep it secure and proper tight.

Please post pictures as you go along!

Whats the next size up in diameter of MDPE pipe?
Does it matter which pipe you choose?
Yellow (gas) Blue (water) Black (is this electric?)
Are they all the same price?
Building sites seem to have more of the yellow pipeing, maybe more obtainable at a cheaper price from a local builder

The thread at https://www.growfruitandveg.co.uk/gr...nel_64642.html is worth a look - especially redser's link in his first post.
