I have one of those mounted on a heavy pedestal base. It has spent at least 5 years outside in the weather and as many years inside. I use it often to hold welding projects during welding and heavy hammering, and it just keeps on keeping on. I never expected it to last this long as it is abused regularly but I have occasionally had to brush off a bit of rust and apply grease and another layer of paint. It's currently coated with Rustoleum stainless spray paint.
