Allegheny Industries, Inc. is an industry leading privately held construction company focused on cellular communications systems.

Our expertise includes tower erection, stealth, DAS, in-building wireless, maintenance, logistics and services. Originally founded in 1996 as Allegheny Builders (a single trade contractor) the company expanded from its core specialty trade to a full spectrum of construction and design services.

What we offer

Allegheny offers logistic and warehousing services from our corporate facility. We stock steel, rebar, mounts and miscellaneous parts necessary for prompt completion of projects. All warehouse and storage areas are restricted, alarmed and monitored by security cameras.

For markets outside of those serviced by our corporate office we prefer to set up on site with an office and warehouse. However, traveling crews are available as an option.

From cellular sites and in-building wireless to maintenance, inspection and service, we are here to assist you in every facet of your project.


Our objective is to take your design concept and transform it into a successful project on time and within budget.

Emphasis is placed on advanced technical training and management skills to ensure you that Allegheny performs at the highest level.

In-house staffing gives us the ability to control scheduling and maintain the quality that you demand.

Allegheny upholds the highest standards for safe operations while providing job completion at the highest level of satisfaction. Guaranteed!
