Hot-dip galvanizing

Postech strength

Did you know that all Postech Screw Piles go through the metallurgical process of hot-dip galvanizing?

It’s a level of protection that ensures our screw piles provide durable protection against corrosion, as well as an estimated useful life of at least 75 years. (CORBEC, Hot Dip Galvanizing, “Sustainable Development”, p.17.).

This is a major consideration when comparing Postech Screw Piles to others. You must be very aware of this to make an adequate comparison.

All Postech Screw Piles are galvanized according to ASTM A123M.

To help you get a better sense of the benefit of galvanized screw piles, we have compiled some guidance and information you might find useful.

Processes

Our screw piles are manufactured from black steel at our Sherbrooke facility.

Once welded, our screw piles are thoroughly washed before being dipped where they’ll undergo a series of physical and chemical transformations.

Lastly, Postech Screw Piles are entirely galvanized as part of a rigorous process under factory-controlled conditions.

Once galvanized, our screw piles go through a final verification, then they are ready to be professionally installed for your project by our expert installers.

Benefits

Why should you buy our galvanized screw piles?

Superior quality components

Galvanized steel’s useful life is predictable (75 years and more) when climate conditions are known. In comparison, non-galvanized black steel is generally unpredictable.

Great resistance to corrosion

Galvanic protection: in the event of a scratch to galvanized steel, the zinc coating will “sacrifice” itself to protect the steel underneath.

Eco-friendly choice

Less corrosion equals less waste. Because galvanized steel won’t rust, the base material can be conserved. Therefore, only minor quantities of metal are reintroduced into our environment.
