More About Steel City

Steel City is an electrical box brand with more than 120 years of manufacturing history, currently produced in Athens, Tennessee. The line covers steel enclosures for switches, receptacles, and fixtures used across residential and commercial electrical installations.

Steel City boxes are designed to meet or exceed National Electrical Code and Underwriters Laboratories requirements, giving electricians a code-compliant option across both new construction and renovation work.

Product Lines

The Steel City lineup includes floor service boxes for concrete, wood, and raised floor construction. These support power, data, and audio and video connections. The line also includes utility and handy boxes and welded outlet and device boxes. Masonry boxes are built for block and brick construction.

Covers, brackets, and prefabricated assemblies round out the accessory side of the line. Boxes use pre-galvanized steel construction as part of their corrosion resistance.

Why Contractors Specify Steel City

Electricians specify Steel City boxes for drawn steel and welded construction built to meet or exceed NEC and UL requirements. That suits both new construction and renovation work.

The masonry box line is built specifically for block and brick wall installations, a construction type that many generic outlet boxes are not designed for. Having floor boxes, wall boxes, and masonry boxes under one brand lets a contractor standardize box specifications across a job that mixes construction types.

How to Choose Steel City Products

Picking the right Steel City box starts with the wall or floor construction type. Masonry boxes are built for block and brick, while standard utility and handy boxes fit typical stud wall framing.

Floor service boxes suit installations that route power, data, or audio and video connections up through a concrete, wood, or raised floor rather than out of a wall. Outlet and device box selection then depends on how many devices, switches, or fixtures the box needs to support. Matching the box's knockout pattern to the conduit or cable being run into it also affects installation time in the field.

Frequently Asked Questions
