Greenhouse shelving - where to get it from?

Hi,

Greenhouse is full to bursting so I am looking to get some of the high integral shelves (which would be about shoulder height). I've been through the link on here but they are really expensive and I'm looking to replace the greenhouse at some point so it's not worth the cost.

Has anyone managed to make this or has any ideas what else I could use?

Thank you

Not quite what you asked but I use a mini greenhouse in mine as extra shelves,this year I've got one of the extra wide ones as my others got trashed in the freak hailstorm we had last year,Sweetpea you will know the one I refer to.

How about these kind of brackets?

quite a few suppliers on-line 

Thanks mum, they are perfect - I looked and looked for an alternative but didn't come up with anything!

Snowdrops - yes I remember that storm, took out most of the panes in my greenhouse and left a rather nice pattern on the bonnet of my old car! I think you got it worse in Burbage though.
