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.
What is hot-dip galvanizing?
Hot-dip galvanizing is an industrial process that involves dipping clean steel in a basin filled with molten zinc heated to 450°C, creating a metallurgical bond between the steel and zinc alloys that results in a pure layer of zinc.
The first alloy created is as strong as the base metal. This is what gives galvanizing its excellent resistance to abrasion.
The smooth and clean outer layer of zinc absorbs shocks, while the underlying layers provide excellent corrosion protection.
Our screw piles are manufactured from black steel at our 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.
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.
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.
Galvanizing, the added value of Postech
As you can see, our entirely galvanized screw piles offer indisputable advantages to your foundations when it comes to the quality of the material used, to corrosion resistance and to the ecological footprint.
Still not convinced? Take a good look at these two pictures and imagine 10 or 15 years after your initial project. Which pile would you choose?
We believe the answer is obvious.
By doing business with Postech, you’re buying more than galvanized screw piles. You are securing your peace of mind knowing your project is supported on a solid and durable foundation for years to come.
