Hi Deon, I hope you don't mind me commenting on your post. But i am Hayden Gleeson from Ceraform Bee Boxes and just found your post relating to our boxes. I realize this was in Nov last year but if you are keen to have a look at one of our boxes i will happily courier you one as a trial box.
Our boxes are made from a 100% lead/metal free eco composite U-PVC boarding, our boarding is the only PVC boarding that is guaranteed to be metal free and we have the verified reports to prove this. Most PVC made around the world is very weak low density signage board that claims to be lead free but the test reports are fake on the cheaper rip-off boarding.
Our boxes are also 2-3 degrees warmer than a painted and dipped wooden box, and they fit the Hive Doctor bases perfectly.
The boarding has been used all over the world for the last 30 years as a external trim or cladding material, it is HIGHLY UV stable and will never get brittle, warp, buckle or ever move from extreme cold or hot climates.
Trevor Gillbanks recently tested these and was happy enough to write me a quick report on his findings, ill attach it for your reference along with our brochure
Cheers Hayden, and if you want a free trial box please message me from our FB page @ Ceraform 100% Waterproof Bee Box NZ or email me at email@example.com
