Reviews
Daniel Herrera
I’ve used Steel City boxes on commercial projects for over a decade, and the consistency is what keeps me coming back. The floor boxes in particular hold up incredibly well during concrete pours—no shifting, no warping, and the service openings stay clean for final trim. Their knockouts punch cleanly every time, which saves my team hours across a project.

During a full mechanical room rebuild, I relied heavily on Steel City utility and handy boxes. The steel gauge feels sturdier than some competitors, and the grounding provisions made it simple to keep everything code-tight without extra hardware. Even after multiple conduit adjustments, the boxes kept their shape and threads stayed smooth.

As a residential remodeler, I appreciate the practicality of Steel City’s outlet and gang boxes. Mounting ears line up perfectly with old-work walls, and the welded construction doesn’t flex when tightening devices. I especially like their masonry boxes for basement conversions—the added depth and rigid structure make routing conduit through block walls much easier.
