Why Convert to Steel Pipe?

  • Zero Ground Rot: Galvanized Schedule 40 steel never rots in wet coastal North Carolina soil.
  • Preserves Existing Panels: Re-uses your good wood pickets and rails—saving thousands compared to a full rebuild.
  • Eliminates Gate Sag: Heavy 3" and 4" posts stop sagging vehicle gates permanently.

Why Wood 4x4 Posts Fail & How We Fix It

In coastal Southeast NC and the humid Piedmont, soil moisture and termites attack wood right at the ground level transition zone. A single failing post places immense shear load on neighboring posts, causing entire fence lines to lean.

Ground-Line Rot & Termite DamageWood rots inside the concrete collar where water pools. Our heavy-wall galvanized pipe is impervious to water, fungal decay, and insects.
Gate Hinge Post Bending & SaggingStandard 4x4 posts flex and twist under gate loads. Upgrading to a 3" or 4" Schedule 40 post provides rigid leverage so your gate latches smoothly every time.
