Why Choose Spartan Posts?
Fence posts rot underground because of moisture, soil conditions, and biological activity.
Spartan Posts have a fiberglass rot protection layer which makes them stand the test of time.
The fiberglass creates a dual-layer, airtight seal that penetrates deep into the wood, locking in preservatives and keeping out moisture and fungi – the primary culprits of rot.
This means long-lasting, reliable fence posts that will not let you down.
