Postech Screw Pile Durability
Screw piles are NOT all equal. Postech screw piles are built to last. All Postech® Screw Piles are hot-dip galvanized according to ASTM A123M. This metallurgical process protects the pile against corrosion, resulting in an estimated minimum useful life of 75 years.
Galvanizing
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.
Processes
Step 1
Our screw piles are manufactured from black steel at our facility.
Step 2
Once welded, our screw piles are thoroughly washed before being dipped where they’ll undergo a series of physical and chemical transformations.
Step 3
Our Postech Screw Piles are entirely galvanized as part of a rigorous process under factory-controlled conditions.
Step 4
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
Galvanized steel has a useful life of 75 years and more when climate conditions are known. In comparison, the lifespan of non-galvanized black steel is generally unpredictable.
Greater resistance to corrosion
If Postech galvanized steel screw piles are scratched, the zinc coating will “sacrifice” itself to protect the steel underneath (a process known as “galvanic protection”).
Eco-friendly choice
Less corrosion equals less waste. Because galvanized steel won’t rust, the base material can be conserved. This means only minimal amounts of metal are reintroduced into the environment.
Galvanizing makes all the difference
Galvanizing, the added value of Postech
Our galvanized screw piles make the better choice for your foundation – for quality of materials used, corrosion resistance, and environmental 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.
Working with Postech means starting stronger on a solid, long lasting foundation!
