Walker Telecomm holds a portfolio of manufacturing NAICS classifications that reflect the technical depth of our work as a low-voltage systems integrator and design-builder. These codes distinguish the assembly, integration, and modification services we provide alongside traditional installation and maintenance. Understanding this classification matters for procurement officers, architects, and program managers evaluating contractor scope and capability.
What the Classifications Cover
Our primary manufacturing classifications fall within Sector 33 (Manufacturing), spanning communications, computing, and electrical equipment:
- 334111 – Electronic Computer Manufacturing. Covers assembly and integration of personal computers, workstations, servers, and custom computing systems where we assemble or integrate processors, memory, storage, and input/output devices into user-programmable final products.
- 334112 – Computer Storage Device Manufacturing. Encompasses manufacturing of disk drives, tape storage units, solid-state drives, and storage subsystems used in data center and enterprise deployments.
- 334210 – Telephone Apparatus Manufacturing. Applies to manufacturing of wire telephone and data communications equipment, including PBX systems, telephone answering and switching equipment, data modems, routers, bridges, and gateways for telecommunications infrastructure.
- 334310 – Audio and Video Equipment Manufacturing. Covers manufacturing of electronic audio and video equipment, including digital video recorders, televisions, amplifiers, and public address systems integrated into facility infrastructure.
- 335999 – All Other Miscellaneous Electrical Equipment and Component Manufacturing. Includes power converters, power supplies, surge suppressors, and specialized electrical apparatus not otherwise classified—common in mission-critical and industrial installations.
- 336411 – Aircraft Manufacturing. Includes aircraft conversion involving major modifications to systems, used when our work involves substantial systems modifications and integration for aviation clients.
Why a Systems Integrator Holds Manufacturing Codes
The distinction between installation (238210 – Electrical Contractors and Other Wiring Installation Contractors) and manufacturing rests on primary business activity. A low-voltage contractor's work shifts into manufacturing classification when it crosses into assembly, modification, or integration of complex equipment rather than simple installation and wiring.
The Key Difference: Installation is about deploying finished products. Manufacturing—in this context—is about integrating components, assembling subsystems, or performing major modifications that transform equipment into customized solutions.
When Walker Telecomm designs and builds a data center, assembles custom computer systems, integrates telecommunications networks with switching equipment, or performs major system modifications on aircraft communications, we are manufacturing. We source components, integrate them to specification, test the assembled systems, and deliver a finished product tailored to the client's operational requirements. This work requires engineering, precision assembly, quality control, and often exceeds what standard installation contracting encompasses.
Federal contractors and GSA Schedule holders frequently hold multiple NAICS codes. The manufacturing classifications signal to federal and commercial buyers that we possess the technical capability, quality systems, and integration expertise required for complex equipment assembly and mission-critical system deployment.
Application in Division 27 and 28 Work
Division 27 (Communications) and Division 28 (Electronic Safety and Security) work—the backbone of our federal and commercial practice—inherently involves systems integration. When we design and build secure telecommunications infrastructure, data center networks, or integrated building security systems, we are not simply installing off-the-shelf equipment. We are assembling, testing, and integrating components into coherent systems that meet rigorous specifications for availability, redundancy, and performance.
Our manufacturing NAICS codes reflect that capability and distinguish us as a solution provider, not a parts installer. For procurement teams, architects, and program managers, these classifications serve as confirmation that Walker Telecomm can handle the technical complexity, quality standards, and systems integration depth required in federal, DoD, and mission-critical commercial environments.
