Any sources for plastic greenhouse-type glazing bars?

[Surfdude]

Got a greenhouse-type structure that was erected in 1999 - acrylic/polycarb sheets set in an aluminium frame. The green plastic glazing bars used to stabilise the panels are well past their sell-by dates, many have slipped out and most have lost their structural integrity.

 

The contractor who used them is long since gone so can't advise where I might find replacements for them. The aluminium framing is absolutely fine, it's just the plastic bars I'm looking for.

 

I did find a single white-plastic alternative that has been used on the roof.. it fits well. But again, I have no idea where it was sourced from. the only ones I can find now all come with the aluminium framing and are, in any case, invariably much wider and deeper.

 

Got quite a few of these to replace, any ideas as to where I could possibly source these things?

Thanks for the link. Could be an option if there's nothing off the shelf available. Not sure how they'd feel about manufacturing the sort of quantities I'd need, though.
