True this. Chrome and nickel content will dictate quality and rust protection. We have some tri-clamps that don't rust but when you put a magnet on them, it will stick. Columns are usually good stainless and the same magnet will not stick at all. Do the magnet test.

Yup, I confirm! Thank you for your quick response!

Hi Paul, I've sent you a request through your email a month or two ago but I guess it fell in spam. I just sent another one now that our project has gained momentum. Look for an adress with a domain name @rocketmail.com. Thanks!
