can anyone tell me is there such a thing as an average thickness off powder coating say 1mm thick or more i dont hence the question

Depends where you go I guess. The guys I use in Newbury, Berks are pretty industrial -which is good cos you get a nice thick coating, but the quality sometimes isn't perfect. They tell me their coating's 5 times thicker than normal paint. 100 microns rings a bell. I must admit, I usually over bore all the mounting holes on parts to be coated to allow for the extra thickness. For example, if I'm bolting something together with 8mm bolts, I drill the holes to 9mm.

how much is 100 microns in feet and inches ,seroiusly no idea how much 1000 microns is anybody help

1 micron = 0.001 millimetres

It will also tend to gather on corners! ;) Bit like hooded youths!  ;D

And yes its hard to remove it out of holes thread etc

hi the right answer to is if it is industrial powder coaters you are going to and it works of a conveyer belt system in some cases they will use a rust inhibitor called keyfoss before coating and it may be actually thinner than going to someone who deals with just wheels and frames a more smaller powdercoaters as they have to lift it in and out of oven and when they spray the powder on it can actually be put on thicker as on conveyor belt system they have only certain amount of time to pain item before it goes on you can only realy pause the conveyor belt for certain time before it goes to next painter to get other side painted
i worked in both types of system and preferred the small oven type more powder on and is normally a lot thicker coat if memory serves me right it was 185 for the industrial conveyor belt system but i can honestly say 1 never unless it was going to marine use did i ever check how thick the lift out system as it is always a lot thicker it tends to be thicker at corners sometimes is realy due to the painter getting a run but for someone not covering a bolt hole is just lazy or a finished surface is just lazy it takes no time to put bung in
i still get certain things powdercoated but if a frame i still just paint with smoothrite powder coating getting to dear (ok im a stingy c***)

hi thanks for that my original post was for the thickness off powder coating as i am turning some s/steel sleeves to hold the mudguards on and wanted to know how much metal to take out

hi turbomangler
your right about industrial powdercoating most of them use a three or four stage chemical bath to so called degrease and allow a better electric charge togo through although that keefoss cant remember how to spell it but know it worked out about a grand for 45 gallon drum for rust prevention is sh** hot for that got a wee stash of that hidden in my shed your right dont take your stuff to an industrial pc it might be a couple of quid dearer in small coaters but worth it as very few have chemical baths and so everything has to be blasted so alot better for staying on
i took fork legs and casings in to a place in glasgow to get done even took out the oil glass window so it was done right went to pick them up do you know they never even masked up inside casing and even when they had blasted it they never wire brushed it so can see wee bits of blast on tiny amount of powder  refused to pay spent 2 hours fixing their muck-up   

sorry was going to finish but posted before i could that was someone that i trained who opened up his own pc but would never go back turbomangler is right go with someone someone who has stuff done and they are happy with.

Just to clarify -& give my local guys a much deserved plug, Albie & Craig of A & C Shotblasting in Newbury, Berkshire, do indeed blast and coat. Everything's hung in spray booths & sprayed by hand, not conveyored. Industrial as in industrial products -they normally coat Aga cookers, Victorian radiators etc. I've even seen them working on North Sea oil rig fittings, but they also handle a lot of car wheels, plus parts for the local custom shop, Valley Gas Speed Shop. They usually spray basic colours, but can do metallics by special order, (they did the metallic silver wheels on my trike). The boys can coat anything up to car chassis size & will be guys I take my truck frame to when it's ready.

As in all things in this life, there's good, bad, and downright indifferent, and"you pays yer money..... etc" however, from what I have seen of Mr. M's projects, they are always of the highest standard of finish, soooo......, use who he uses, simple!!!  Morrag

i have known  a the md of a powder coaters for about 20 years now and due to location are heavily involved in the oil sector and i have to say they do a good job for me , theres a new owner now and ive already got a good connection with him due to work and he just done some more stuff for me and made a superb job , hes also willing to give a shot a coating my new frame in a material i thought id have to go to areocoat for and the plus is hes gona do it as a test so ill only get charged for materials , if it comes out with the odd mark i think i can live with that and lets face it im never gona be on the pages of BSH receiving a cheque for 5 k am i   :P

Why not?  ;D

erm .............cause ....... self doubt and cash and time and and and you know

Its all relative, when Grum was having his Pinto frame done he sent it from Stockport to the coaters that Desperate uses. Was a real qaulity job too. Uses Smoothrite myself though cos I is a cheapskate too ;)

Never been impressed with any powder coat finish, Two-pack paint is a lot more durable especially for the underside of trikes which take a battering..

Powder-coat's quite soft. It tends to dent or scuff, rather than chip & flake like paint, & is usually thick enough to be able to buff surface damage out.
It's also reasonably petrol & brake fluid proof -prolonged exposure to either will soften it, but if you wipe it off with a wet cloth it usually survives unharmed. Any discolouration can be brought back with a spot of T Cut. Coating normally works out at about half the cost of paint. Biggest fault is the way water gets underneath it through any damaged areas & lifts it away from the metal.
As you say, it's down to personal choice, but I powder-coat everything I can these days.
