These are the beam clamps I normally use: https://www.garvinindustries.com/jfc-3816 With flat staves, they tend to not sit quite as far onto the bands as I'd like, but it does work, and we've had dozens of them hanging on that type of silos for years with no issues. The parallel beam clamps Chuck mentioned do look like they might work better with flat staves though (or they might not work at all... it's hard to say just based on pictures).
