30 gauge unuff?

["Eric" <lukehart@mis.net>]

Hello list,
I am repairing a couple of holes in my floors.  The holes are about 6 inches
long and about 3 inches wide.  Someone at work gave me a roll of 30 gauge
aluminum and said it would work for my needs.  When I asked him if it was
strong enuff he said it would be very strong once it was pop riveted.  The
metal seems a little flimsy to me.  Any thoughts on this topic.
TIA
