We offers a variety of Steel Pole types to meet your specific communication tower needs. Our Tapered Steel Poles and Flanged Steel Poles feature designs that are aesthetically pleasing and blend well into the environment while requiring minimum space for installation.
All of our Steel Poles are hot-dip galvanized after fabrication to ensure years of corrosion free use.
Tapered Steel Poles are designed with base diameters from 2' to 6'. These minimal site requirements lower lease rates and/or acquisition costs.
Tapered Steel Poles are designed for rapid installation, making them ready for service quickly while meeting the demands of today's PCS, cellular, and other communication tower environments.
We provide structure and foundation design services with approved engineering documents, in any state, by a registered professional engineer.
Flanged Steel Poles are easy to handle and install. Precision fitted connections allow quick assembly of the modular sections and the top platform, sidearms or mounting frame.
Our Steel Poles can be modified with an inside flange for better aesthetics.
Internal Flanged Steel Poles are one continuous pole. Sections from 5' to 50' can easily be added should future expansion be required.
Our broadband Light Duty Poles are a series of pre-engineered, light application poles.
Light Duty Poles are designed for direct embedment at the base with a quick aggregate backfill.
Poles are available in heights from 30 feet to 150 feet.
Typical uses include
• Broadband Communication Poles
• Wifi
• Security Camera Mounts
...and other lightweight communication pole applications.

concentrated caustic solution elevated to a temperature ranging from 150 to 190-
degrees Fahrenheit. It is then pickled by immersion in a heated sulfuric acid solution
of 6%-13% concentration, controlling the temperature between 150 and 190-degrees
Fahrenheit. It is next rinsed clean from any residual effects of the caustic or acid
solutions by immersion in a circulating fresh water bath.

flux solution heated to 130-degrees Fahrenheit. The solution's acidity content is
maintained between 4.5-5.0 pH. The assembly is air dried to remove any moisture
remaining in the flux coat and/or trapped within the product.
