ROGUE TROOPER Posted September 12, 2006 Share Posted September 12, 2006 So whats the best coating for a 25mm x 25mm x 10mm mild steel with 4 holes each corner 2 with M10 threads 2 straight through holes that will be clamped? My thoughs are: Powder coated Galvanised Anodised Painted Or make it out of Stainless! It will be a high stress pull apart area lengthways!

Jon White Posted September 12, 2006 Share Posted September 12, 2006 Whats the application and environment? How nice does it have to look? Jon Quote Link to comment Share on other sites More sharing options...
sgnas Posted September 12, 2006 Share Posted September 12, 2006 If it's threaded I would go for electrogalv/anodized if I were paying. Painted if I were being tight or Stainless if I had a bit the right size, pretty unlikely if it's 10mm thick! Quote Link to comment Share on other sites More sharing options...
gaf lad Posted September 12, 2006 Share Posted September 12, 2006 galv. if its out in the elememts. zinc plate and passivation for general use and you could paint it later when the passivation looks tired/worn. as zinc and pass only lasts about 120hrs in a continuos salt spray test. powder coat is ok if you use external powder and you dont chip it with wear as it will rust and flake in no time.

bishbosh Posted September 12, 2006 Share Posted September 12, 2006 Hot dip galv for me. You'll just have to clean out / re tap the threads afterwards. Quote Link to comment Share on other sites More sharing options...

Les Henson Posted September 12, 2006 Share Posted September 12, 2006 Painted if I were being tight Richard will be using a can of emulsion from the pound shop then Les. Quote Link to comment Share on other sites More sharing options...

If I were you I wouldn't worry too much what finish you put on it, there won't be much metal left after you drill 4 10mm holes in a piece of 25x25x10mm steel. Seriously, if it is that small I can probably send you a bit of stainless, the cost of any professional finish will be preclusive. Quote Link to comment Share on other sites More sharing options...

white90 Posted September 14, 2006 Share Posted September 14, 2006 properly applied POR 15. if it's good enough fot ship hulls then it's good enough for me POR15 should be POS15 it is utter rubbish applied exactly as instucted peels off in sheets biggest waste of time/effort ever. I only use: zinc rich red oxide primer topped with Halfords matt black enamel lasts longer and is harder wearing Quote Link to comment Share on other sites More sharing options...
s2hotdog Posted September 14, 2006 Share Posted September 14, 2006 Go for stainless - The galvanisers wil lose a small pice that that Cheers Steve Quote Link to comment Share on other sites More sharing options...
