Hello Forum
My first post,
looking for a bit of advice and peoples thoughts
Rust & Strainer posts made from eg Galvanised Scaffold Tube or larger diameter.
Basically, a 9 foot galvanized tube, concrete foot/base plate (eg set in a bucket), and further up a breastplate to go to a dug 4-foot deep hole (earth rammed back in).
No thinking of the strut at this stage if any.
Why problems with the Wooden posts rotting including creosoted eg reused utility poles and used concrete sleepers weigh 250kg so not practical.
Lot of work to get old posts out digging holes so want a solution that lasts.
With regards to rust no problems I can see with the concrete and can put plastic on the pole top (prevent rain from going down the tube).
However, would like to drill holes in the galvanized pole to fit stainless or galvanized bolts to hold pieces of timber above ground to fix stock fencing.
Will, there be a lot of rust if the holes in the tube are not treated, how long service life, sorry for my naivety?
Dissimilar metals steel, Zinc, and eg stainless bolts increase corrosion, maybe, therefore, galvanized bolts best?
To try to extend the service life of cut/drilled exposed galvanized steel could paint the holes cut areas with a primer (believe epoxy is the best) after, (after cleaning, and T wash for Galvanised area).
However, I have noticed even the epoxy paint surface has been compromised with steel rope rubbing the surface in a related application.
Also, sourcing a larger than diameter tube than scaffold pole might be advantageous for End Strainers (tieing off) at a fair price?
thank you
