One more question, one factory said they will use raw steel tubes for the fence and the other said they need to use low carbon steel tubes, because they will hot dip galvanize them. Is a certain type of steel better for bonding/adhesion?
Also they have the pre galvanized G60 that I mentioned...
I will look into the etch primer and see if they can apply it, but not sure if I can trust them to do it properly or use the correct one. A lot of the time they will say they will use a certain brand (AkzoNobel powder coat) for example but in reality they use some chinese brand you've never...
Thanks everyone for all the replies and information.
I have received a sample and now in the process of trying to verify the thickness of the galvanization, and I saw a cheap option would be the "PosiPen". It has a 10% margin for error which is large but will still work for my application. The...
Thank you, definitely would not have been able to calculate that myself.
Looks like tech99 proposed .003 thickness of coating and the company in China can offer .0023 which is about a third less of the thickness proposed.
Their other (standard) option was 1/8th of the .0023!(at 50 g/m2). Just...
Very helpful, thank you.
If not electoplated zinc, what other kinds are there? I am not familiar with the terms.
These will be welded and then dipped in zinc I believe. The company said they offer 50 g/m2 thickness of coating and 400 g/m2 of coating. Do you have any idea how to convert this to...
Good point, however I am not too worried about the powder coat peeling off. It can easily be touched up but I am more worried about the lack of oxidation or crevice corrosion. As long as it doesn't rust and it oxidizes, touching up with paint will not be an issue.
If it does rust then it will...
Thank you for the idea. I will also try to find a company that does only the dipping part to find out how many times it is dipped.
From what I've read is that it's dipped twice during production; not during it's life, at least for powder coated fencing. I don't know if they let it cool and...
I need help with a galvanized steel fence that will be powder coated black. I am ordering it from China and I don't know what specs to ask for in order to make sure it lasts 25+ years easy without maintenance.
I need ideas to fullproof the longevity factor on this fence. I am aiming to get to...
