Well, 316 is proprietary.
Bad example. It's for severe environments. Never seen it drawn into rails, just high pressure pipe and casting or machined components. Remember too, a stanchion is a member of a "team". A team of them work together for strength. Kinda like trees.Oh, as far as costs, have you priced copper lately? The price of most metals is 'supply and demand' driven. Katrina has driven up our constructions costs here by 50%. Of course most of that is greed. The construction companies see what a huge profit was handed out to some companies by the Feds and they want their share. Maybe things will get better because of the election. Better quit now before Phil gets me.
