Galvanising questions

Will they galv rusty metal?

They seem to either media blast or Acid dip as routine before galv, so rust shouldnt be a problem

heavy surface rust ok it strips in the acid but takes a little longer ,paint oil and grease will not strip so all need to be removed before sending to galvanizers

remember any hollow section going to galvanizer has to have all the vent holes correctly drilled or they will charge for each hole they have to drill

and they know how to charge for drilling

Hiya.Is there a hot dip galv place in the North West-Lancs area.I have a small sprayer I was gonna galv.been painted once over original with Hammerite,failed. Would like to take tank n bits bobs off and sort the frame properly.The band around the middle of it is the worst. Drilled holes in it underneath to let water out,as didn't have any,but still rusting badly.
Any help please.
Thanks.

thanks for the replies guys. tried painting things before and not had much luck with it near cow muck , so im thinking proper job this time.

Cows muck will strip galvanizing fairly quickly too.
land rover chassis that are galvanized rust where the mud sits.
It's not a permanent coating.

I rather think there is galvanising and galvanising. I suspect chassis part are in the dip for a few seconds.

Nah, well galvanised Chassis, besides, does it matter how long it's in the tank for?
it's a sacrificial coating it doesn't last forever. Same as zinc flashings getting thin and then leakig.
i think zinc played may be different though.

in the uk galvanised coating is used up at a rate of up to 2.5 µm / year outside but on a farm etc this rate can be far greater and you can spec a extra heavy galvanised coating

small jig work (stuff that needs hanging with wire on frames to dip) should be about £350 with the zinc surcharge
