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

Postech’s galvanizing process

STEP 1:  CREATING THE PILES

The black steel arrives at our factory in Sherbrooke in the form of raw plates and tubes. We then carve and weld these pieces into black piles.

Galvanizing process

STEP 2: GALVANIZING THE PILES

Our black piles are then sent to our partner, Corbec, where they will undergo several chemical baths before being immersed in liquid zinc to be fully galvanized.

STEP 3: APPROVING THE PILES

The galvanized piles return to our Sherbrooke plant where they go through a final quality check. Approved piles are sent to Postech dealers who will install them for customers.

Benefits

Why buy Postech 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.
