Hi all,

I have a nice bit of plate that I've been meaning to use for a welding table. I'm just currently stuck trying to think of what would be suitable specifications of the steel for the frame.

The main concern is the plate is 1500x1000x25, so around 300kg on its lonesome. Since I want it on caster wheels as well, it'll have a few directions of force on it at times.

I don't suppose anyone has a simple rule of thumb for calculating what would be suitable frame material?
50x50x5 or 65x65x4 SHS is what I've been considering, would that be suitable for ~600kg of loading?

Drat, now that I think about it, my 150kg rated ebay casters might not be the best for my small fear of being crushed

Thanks in advance!
