Product Overview
The Steel Tech Lights 20FT × 4-Inch Square Steel Light Pole is a commercial-grade outdoor lighting pole designed for parking lots, retail centers, industrial properties, schools, campuses, office buildings, public areas, and other exterior area-lighting applications.
Constructed from high-strength steel tubing, this straight square pole conforms to ASTM A500 Grade B specifications with a minimum yield strength of 46,000 PSI. The 20FT model features 11-gauge steel construction with a 4-inch square profile.
For exterior durability, the pole receives hot-dip galvanizing and a textured architectural bronze powder-coat finish.
The pole includes anchor bolts, a two-piece formed steel base cover, and a reinforced hand hole and cover with ground screw. Standard poles are predrilled on four sides and include a polycarbonate top cover and plugs for unused mounting locations.
