DIY Netting frame

ispookie666

I'm looking for ideas or suggestions for building a frame over a few raised beds and ground-planted ones. I looked at a few sold but would instead make one myself. 

I was thinking 

To make them walk in(we are not tall!)

6ft angle irons, preferably galvanized ones, and bury them 1ft deep; size - 25mm x 25 mm and 3mm thick 

Drape them with butterfly-proofing nets, and use either ties or cable ties to fix them.  

Will I need horizontal angle irons to prevent the nets from sagging?

On the allotment members use lengths of blue water pipe and scaffolding netting. Geoffrey Hamilton gave instructions on Gardeners’ World. On our windy site I used Poundland metal tent pegs and bricks to hold it down. 
It was easy to raise one side to get access to the crop, and was easy to store in the shed.

I might borrow that idea partially.  Probably use PEX hose or galvanised steel conduit for the horizontal supports 
Are the blue pipes rigid or do that have to be made into arches?

Made into arches. It's appeared on gardening programmes for decades so tried and tested.
I made my fruit cages with wood  battens and angle bits to screw in. Then stapled the netting to the wood. Cheap and sturdy for years. 
Both you can walk in.
