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.

Hot-dip galvanizing

Why is hot-dip galvanizing important?

Hot-dip galvanizing is one of the most effective ways to protect steel and metal from rust. During this industrial process, clean steel is dipped in a basin filled with molten zinc heated to 450°C. This creates 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 abrasion resistance.

The smooth and clean outer layer of zinc absorbs shocks, while the underlying layers provide excellent corrosion protection.

What is the lifespan of a Postech Screw Piles

Lifetime

The usefull life of our helical piles will vary depending on the type of soil. In fact, the more the soil is dry the more the screw piles will have longevity of life. Our screw piles can indeed last between 75 and 865 years.

The soil and it’s moisture content will have the greatest impact on how well your screw piles will do once installed. They are the main factors of corrosion. One must not worry, we can still offer a lifetime warranty!

Postech’s galvanizing process

Step 1

The black steel arrives at our manufacturing facility in the form of raw plates and tubes.

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.

Superior quality

Galvanized steel has a service life of 75 years or more under known climatic conditions. In comparison, the life 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 means less waste. Because galvanized steel doesn’t rust, the base material can be conserved. This means minimal metal is returned to the environment.

Galvanizing makes all the difference

Galvanizing, the added value of Postech

Our galvanized screw piles are the better choice for your foundation – for quality of materials, corrosion resistance and environmental impact.

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 think the answer is obvious.

When you do business with Postech, you’re buying more than galvanized screw piles. You are buying the peace of mind of knowing that your project will be supported on a solid and durable foundation for years to come.

Working with Postech means starting stronger on a solid, long-lasting foundation!
