The CL-SSS Square Straight Steel Light Pole is a heavy-duty commercial lighting pole engineered for strength, durability, and long-term outdoor performance. Manufactured from cold-rolled, weldable carbon steel tubing conforming to ASTM A500 Grade B, this square steel pole delivers a minimum yield strength of 45,000 PSI for superior structural integrity.
Designed for parking lots, roadways, retail centers, municipal installations, campuses, and hospitality properties, the CL-SSS series features a reinforced 4-bolt steel base plate, internal ground lug welded opposite the hand hole, and a high-performance powder-coated finish for corrosion resistance.
Available in heights from 10 ft to 39 ft, multiple square profiles, and 11-gauge or 7-gauge wall thickness options, the CL-SSS provides exceptional wind load performance up to 140 MPH depending on configuration.
Backed by a 3-year manufacturer warranty, this square steel lighting pole is ideal for high-wind and high-traffic environments.
