Indeed, all Postech piles are hot-dipped galvanized according to the standard ASTM A123M. This standard is especially designed for the addition of a zinc coating (hot galvanization) on steel and iron products.

What exactly is galvanizing?

Hot-dip galvanizing is an industrial process that involves submerging clean steel in a 450oC molten zinc basin to create a metallurgical bond of zinc alloys covered by a layer of pure zinc.

Rust undermines scratched paint, but not galvanization

Corbec, one of our galvanisation partners, tells us this: « Here’s what happens to a scratch on painted steel. The exposed part of the steel corrodes and forms a rust bubble. This rust bubble, larger than visible, swells and lifts paint from the surface of the metal forming a blister. Meanwhile, the corrosion cavity and blister continue to progress. »


So always make sure you have a galvanized pile, welds made by certified welders and quality steel so you can keep your investment for a long time without rust.
