25G self supporting tower | 3 legged self-supporting commercial towers

Self-supporting towers, sometimes referred to as “free standing antenna towers” or “wireless communication towers” are the most popular and versatile type of structure used today in the wireless industry. At Nello, we specialize in self-supporting towers with the following features:
Available in solid leg, tubular leg and angle leg

 

Please inquire about custom designed steel self-supporting towers that are built to specifically suit your needs. Contact us now. 

Designed to latest EIA/TIA-222 standards (currently Revision F or G)

Galvanized per ASTM 123 standards

Extensive engineering package detailing member size and steel grade

Towers are available in other sizes and heights.

For larger self supporting towers, manufacturers often provide climbing provisions on each of the tower legs, step bolts being the most common. Since lighting fixtures and antennas may be distributed on any of the three tower legs, it must be practical to access each leg individually. Some designs provide for welded sections in the top 20’ to 80’.

There are multiple manufactured designs, each one having installation or shipping benefits, from tubular, solid and truss-style solid legs to back-to-back angles. When estimating your installation cost, identify whether the design will affect the total number of days budgeted. In example, an inexperienced crew erecting a back-to-back angle structure might take 5% to 10% longer to construct the tower.

Available in heights from 20’ to over 400’ (7m to over 140m)
Our in-house professional engineering team uses a proprietary design program that iterates through dozens of configurations to find the most cost-effective tower combined with the most efficient foundation design possible for each project. By utilizing this iterative design analysis, Nello is able to save our customers and their erection contractors both time and money.
