The basis for the fence can be made of brick, wood, metal, concrete. There is another option - fence posts made of asbestos-cement pipes. The most commonly used metal. How to protect metal poles from corrosion so that they will last for 50 years or more?
Sometimes, even after 3 months of building a fence, you can see traces of the first corrosion on the posts and logs. Many people complain that metal pipe poles rot after 10-20 years. Concrete can save pipes, then only if it is taken out above the ground level so that water does not get into and stagnate. How to avoid corrosion at the bottom of the structure?
You can treat the posts with a metal primer and then paint them with enamel or bitumen varnish (in cans). However, the enamel is fragile and not quite suitable for a fence. There are other, cheaper and more reliable ways.
Fence posts can be square, round, rectangular. There are screw. Round pipes are cheaper and more durable than profiles. Most often they use a size of 57x3.5. The thicker the pipes, the longer the service life.

Usually the pillars are done like this: a hole is dug, a pillar is installed (pre-coated with a primer) and the pit is filled with concrete. The lower part remains unprotected.
Primer and enamel will not save. Therefore, you can do this.
You will need an empty plastic bottle, cement mortar, trowel. A metal post is installed. The solution is poured into the pit. Formwork is made from a plastic bottle. Cut off the neck of the bottle and the bottom. Then cut the bottle lengthwise and put it on the pipe, when the solution has not yet frozen. Then the solution is poured into the formwork from the bottle. This method is useful for the construction of various structures, including fence posts.
2 way of protection
Do-it-yourself anti-corrosion coating made of plastic. Any pieces of plastic will be needed. For example, an old case from a computer system unit, etc. Prepare a container for preparing a liquid solution.
Use pliers to break the plastic (as small as possible). You can use plexiglass. Dissolve the plastic with xylene. If you are using plexiglass, then solvent 646 and a little xylene are suitable for it. It will dissolve overnight.
Fill the plastic with solvent and close the lid tightly. We leave for a day, two. If the mixture is too liquid, then leave with the lid open to allow the solvent to evaporate. If thick, add xylene.
