Square Tapered Steel Poles

The lighting standards listed here are designed for ground-mounted applications. Standards mounted on structures require factory consultation. All of our products are available as direct-burial poles — contact our Project Management team for exact catalog numbers and pricing of such poles.

Pole Shaft Specifications

The pole shaft is fabricated from United States coil stock.  It is a weldable-grade, hot-rolled commercial quality carbon steel ASTM A-595 Grade A with a guaranteed minimum yield strength of 55,000 psi after fabrication. It is a one-piece construction with a full-length, longitudinal, high-frequency resistance weld and is square in cross section, having a uniform taper of approximately 0.10″ per foot in length.

Base Plate Cover

A full base plate cover is supplied. For 25′ and 30′ poles, the base cover is steel. For 20′, 25′, and 39′ poles, the base cover is made of two-piece formed sheet steel.
