Galvanising a butt hinge

[neilgrahamirwin@hotmail.c]

Hi Guys, I am making a product that is for use out doors and it requires a butt hinge like below-it's a bit like a hinged bollard type of thing

http://www.ironmongeryonline.com/product/75mm-Double-Pressed-Butt-Hinges-to-Weld---Self-Colour/724/

The butt hinge will be at ground level so will be subject to a lot of rain/moisture etc so I am thinking it (and the whole product) will need to be galvanised-is it possible to galvanise a butt hinge like this given that it is preassembled or is there a better way of doing this? Any suggestions appreciated
many thanks

Neil

No chance to galv one after buildup. and even then you will have wear contact surfaces that will rust.

Fit a stainless one

Use Brass hinges, the pin is still steel but if you oil it well it will last. Decent steel ones will last years with a coat of paint in our climate, the hinge is not exposed much if it's fitted properly.

hinges

Stainless not an option??-- brass bushed, stainless pins

Yes, i thought about stainless-I guess I would have to screw the hinge to the to pieces being hinged or can you weld stainless to mild steel? I wouldn't want to make it all out of stainless?

No Problem welding SS to Mild

You wouldn't really want to weld the hinge onto the galved post....would you....

not without a bloody good extractor!

That aside, the anti rust coating you have put on it will be compromised.

cant u send it for galv'partly assembled,with adequate clearances for zinc,then assemble it on-site.If you did mark the surface & expose the steel,zinc posseses sacrificial action so to a large extent it will self heal although you often get a brown stain line.
