I am new to beekeeping, only been at it for 12 months or so. I inherited a hive or 2 and I am in the process of slowly increasing the number, and with limited knowledge I have done a lot of research and looking at hives, and I decided to head down the plastic path to supplement the aging wood supers of varying age and robustness.
After many hours of looking at the various plastics out there, I decided on Nuplas, partly due to cost and I have Nuplas water tanks, so I guess they know how to mold plastic :-D
(Search for Nuplas bee hives)
I ordered 6 10 frame supers and they arrived quickly from Melbourne, and were really easy to construct, only 12 stainless screws and a battery drill and the job was done within 1/2 hour.
They fit perfectly with the wooden supers, base boards and lids that I have (Nuplas don't have plastic bases and lids yet for 10 frame, but they did assure me that they are one the way later this year).
So far I am happy with the choice, they haven't warped or changed colour yet,and the bees don't seem to notice, they produce the same in wood or plastic as far as i can tell. As soon as the bases and lids are ready I will be purchasing them and some more supers to build up some more hives.
