About to purchase an old farm on a few acres and I want to put up a 4' fence all around the 2 acres made out of corrogated iron post & rail. Problem is unless there is a raised concrete footing for the fence sheets to sit above the soil, the cheapness of todays iron means the sheets begin to rust in very short time (months). Because of the size of the property the raised concrete footing is a big job that I don't really want to do. The other alternative is to just dig the sheets of iron into the soil a few inches that I see a lot of other people do, which is where the rust starts. I do need to dig the sheets in because we have lots of snakes and I want a barrier to keep them at bay from our kids and animals. My question is: What can I treat the sheets of colourbond iron with before putting the bottom 6 " in the soil to stop rusting ? Not bothered if it starts to get eaten away in 10 years or so, but a few months is not on. I thought maybe getting some of that brushable bitumen coating for the part that goes in the soil. Would this work, or is there a better suggestion from members ? Re: Prevention of rusting fencing iron ? 3Nov 21, 2011 7:57 pm Problem I think with that Casa, is that the sheets are already painted (colorbond coating), painting a cold galv paint on it may just prevent the deteriation for a short period, before he rust process begins ? My thought is the bitumen coating is a thicker and more heavy duty process. I do remember years ago a bloke that I knew who coated his boat trailer in bitumen paint and it was immersed in salt water every time he launched his boat and it's protection quality was quite good. I am still open to suggestions, and yours is not yet rules out. I think once I have a few more suggestions I will then contact all the manufacturers and see what they think. Re: Prevention of rusting fencing iron ? 4Nov 21, 2011 9:00 pm You good thing about a cold galvanising paint coat is even if the area is cut, the zinc in the paint offers protection. If the bitumen coat is cut, it will rust at that area. Having said that the bitumen breaks would not be large enough to cause the sheet to break in two. So on second thoughts either the bitumen galvanising would work.
