Galvanized Screening & silicons... your thoughts?

[CpnObvious]

I feel the need to preface this with a disclaimer that I know and understand the "risks" to humans about consuming foods prepared on galvanized material...

That being said, I have a few questions:

1) I'll be making some screened bottom boards of my own design.  For this purpose does anyone see any potential harm by using 1/8" galvanized hardware cloth as the screening?

2) I was given (and like the design of) a feeder.  It has 1/8" galvanized hardware cloth for bees to climb on to get the syrup.  Should I replace the mesh with a different material?  If so, do you have any recommendations?

3) Do you like movies about gladiators?

Uhhhm... Not sure how #3 got in there....  Uhm, yeah.
Thanks for the advice!

I have some hive-top feeders that I had to run a bead of silicone calk around the screen because the bees were crawling under the screen and getting into the syrup and drowning.

(not a great picture, but if you look closely you can see the white bead of calk around the screen)

the problem with Galvanized is when it remains in contact with honey, and through the chemical process leaches into the honey. I wouldn't hesitate to use it for screens.

    It depends on the gladiator movie.

Exactly what Scott said.

I thought I'd post the combination Landing/Screened Bottom Boards I made.  The removable tray underneath can hold a pan of oil (not sure if hive beetles are an issue in my neck of the woods).  The "tray" is made of 3/16" melamine shower/marker board with the smooth/sealed side down to help prevent moisture damage.  I also figured if it gets super hot that it can be removed to improve air circulation.  I'm just not sure how hot is "too" hot that I'd have to worry about that.

Nice work, but either keep oil in it or remove it. You may or may not have SHB, but you definitely do have wax moths. That will be a haven for them to raise if there's no oil in it.

The galvanizing will not come into contact with the honey so that is not an issue. Depending on the chemicals used and application methods in mite treatment, some of the chemicals can cause a reaction and cause the galvanizing to erode and the screen to rust. but other than looks the service ability of the screen is not effected, nor are the bees from this deodorization.

Galvanized screen wire won't hurt anything. Neither will silicon. The clear, 100% silicone is approved for food contact.
I work in the BioTech industry. We manufacture grafts for human implantation. Our lowest rated clean room is infinitely cleaner than a hospital operating room. Clear silicone is approved for use in these rooms. It will not support biological growth and is non-particulating. I think it will be fine in a beehive.
