Help with Load Limits of 28 ga. Steel?
Im in the middle of designing a chimney cap which I will build myself out of steel. I am making the top and bottom out of ready made galvanized steel trash can lids. (Reason: cheap!)
I'm concerned in my design whether or not I will need to support the center of the top to take more weight (from snow and ice)
The manufacturer says that the lids are made from 28 - 30 gauge steel. If the lid is 21" round and only supported at the edges, what is the weight limit?
There will; be 8 supports between the top and bottom, along with a full 360 degree mesh made of hardware cloth.

I wouldn't want to try standing on it (as 280 pounds) but I can't imagine any snow or ice load would damage the lid itself - as Born says, the supports are the critical area.
