Corrosive enviorment, but the customer doesnt want something plastic.
Its actually to replace galavanised MK metalclad sockets mounted on Granite that has rusted to peices after 10 yrs.
Well if the galv lasted 10 years I'd suggest just replace it with the same. Also with stainless steel you need to stick to 316 or better, nowadays they have a habit of calling 3CR12 stainless and it will corrode as fast as mild steel in some environments. The fashionable type domestic stainless stuff won't pass muster in an industrial environment, they look pretty but that's where it ends. Decent grade industrial stainless products cost a small fortune, check out the web for a manufacturer who caters to the dairy or food production industry.
When I say 10 yrs, they began to rust after a couple of years. Its actually in a church fixed to the granite colums. As soon as they rust they begin the mark the souding areas. I was looking for a better product than standard metal clad sockets.
Nor did i until I saw the 2ft circle of brown rust stain around each of the sockets. Its not damp, but the metalclad sockets and fixings seemed to have reacted with the Granite.
First time ever seen it, but its there. The normal m/clad sockets work well, the supply cables are MICC so need a 20mm entry. Like the other replies said, I think the domestic type decorative sockets wont last.
