I bought a electric staple gun at Sears over 20 years ago that shoots 3/8ths staples with up to 1/2 inch legs. I did the entire roof of our house (2400 square feet) 4 layers of 15 and 30 pound roofing felt with it. It still works though it misfires fairly often. I think something like that would work as long as the load does not put the staples in tension.
