Key Features
One-Piece Square Steel Shaft
Fabricated from hot-rolled welded steel tubing in a square profile with a minimum yield strength of 55 KSI. Available in 11-gauge (0.120\u{2033}) wall thickness.
Direct Embed Installation
No anchor bolts or base plate required. The pole is embedded directly into a concrete or gravel foundation — 3 ft deep for 10'–15' heights, 5 ft deep for 20'–25' heights.
Anti-Rotation Aluminum Wings
Welded aluminum wings at the base of the embedded section prevent rotation and ensure secure, stable placement within the concrete foundation.
Pre-Drilled Four Sides
Factory pre-drilled on four sides with UV-stabilized polycarbonate plugs and removable pole cap. Supports 2@180\u{00B0} or 4@90\u{00B0} side-mount luminaire configurations.
Dual-Zone Finish Protection
Above-grade surface: powder-coat over galvanization. Below-grade section: asphaltum coating for long-term corrosion resistance in direct-burial conditions.
5-Year Structural Warranty
Every SSSE pole is backed by a five-year structural warranty. The finish and paint are covered by a separate three-year warranty for lasting performance assurance.
