Description
The 100 × 75mm hardwood post is denser, harder, and far more resistant to physical damage than its pine equivalent.
Treated to H4 Hazard Class with CCA preservative — rated for direct in-ground contact. H4 hardwood posts combine the natural durability of hardwood species with additional chemical protection against fungal decay and subterranean termite attack.
Pine vs Hardwood Posts — Which Should I Choose?
Pine posts are lighter, easier to handle, and more affordable — a solid choice for standard residential fencing. Hardwood posts are significantly heavier and denser. If budget is the primary concern, pine is fine. If longevity and durability are the priority, hardwood is worth the investment.
