What Cerro Wire does
Cerro Wire, operating under the Cerrowire brand, is a US-based manufacturer of copper and aluminum electrical building wire and cable products headquartered in Hartselle, Alabama. The company's core technology covers Metal-Clad (MC) cables with interlocking aluminum armor, nonmetallic sheathed cables (CerroMax NM-B and UF-B), service entrance cables (SER and SEU), THHN/THWN-2 building wire, flexible cords (SJOOW), and specialty products such as annunciator bell wire, lamp wire, landscape cable, and healthcare- and fire-alarm-rated MC assemblies. Differentiated features include a UL-verified 5.09 lb average installation pull force, a patent-pending Armor Coding System with sequential footage and chevron indicators, and CerroMax color-coded jackets on 14/3 and 12/3 NM-B products.
Cerro Wire generates revenue through one-time product sales of wire and cable, manufactured at four facilities in Alabama (two: Thompson Road and Byrd Road), Georgia (Carrollton), Indiana (Crothersville), and Utah (Ogden), with an additional retail distribution office in Kennesaw, Georgia. Pricing is not publicly disclosed; customers are directed to distributors and retailers for quotes. The company is a wholly-owned subsidiary of Marmon, itself a portfolio company of Berkshire Hathaway, providing corporate backing and procurement scale.
The go-to-market is dual-channel: commercial and industrial customers are served through electrical wholesale distributors and a nationwide network of manufacturer's representatives, while residential customers, licensed electricians, homebuilders, and DIY homeowners purchase through national retailers including Home Depot and Menards and regional outlets like House-Hasson Hardware and Rural King. Customer segmentation is horizontal across residential, commercial, and industrial applications with no named end-customer dependencies in the disclosed data.

Cerro Wire competitors and assessment
Company assessmentDirect peers
- Southwire Company: Southwire is the largest US-based manufacturer of wire and cable, including building wire, MC cable, and portable cord products sold through identical electrical wholesale and retail channels. It is the most direct competitor to Cerro Wire across residential, commercial, and industrial segments.
- Encore Wire (Prysmian): Encore Wire, acquired by Prysmian in 2024, is a leading US building wire manufacturer focused on NM-B, THHN, and MC cable products serving electrical distributors. Its product mix and channel strategy directly overlap Cerro's residential and commercial building wire business.
- Service Wire Co. Service Wire is a US manufacturer of building wire, MC cable, and portable cord products serving electrical wholesale distribution. It is a direct mid-tier competitor to Cerro with overlapping customer base and channel strategy.
- Houston Wire & Cable (Genuine Cable Group): Houston Wire & Cable, now operating as Genuine Cable Group, distributes and supplies building wire, portable cord, and cable products through the same electrical wholesale channel as Cerro. While more distribution-focused, it competes directly for distributor shelf space and contractor specification.
- Omni Cable: Omni Cable is a US master distributor of electrical wire and cable, including building wire and MC cable products from multiple manufacturers. It is a critical channel partner and competitor for shelf space at electrical distributors, comparable to Cerro's distribution positioning.
- American Wire Group: American Wire Group is a US-based manufacturer and supplier of building wire, including aluminum and copper conductors for residential, commercial, and utility markets. It is a direct mid-tier competitor, particularly in aluminum building wire where Cerro also competes.
- Republic Wire: Republic Wire is a US manufacturer of copper building wire and cable products serving electrical distribution. Its product portfolio (NM-B, THHN, MC cable) overlaps directly with Cerro's core residential and commercial building wire offerings.
Broad incumbents
- Prysmian Group: Prysmian is the world's largest cable manufacturer with significant US presence after acquiring General Cable and Encore Wire. It competes broadly across building wire, utility cable, and specialty cables, providing scale and procurement leverage that structurally pressure mid-tier US players like Cerro.
- Belden Inc. Belden is a US-based manufacturer of specialty cables, including industrial, networking, and broadcast cabling, with some building and infrastructure exposure. While its core is more specialized than Cerro, it competes in adjacent cable categories and shares electrical distributor channels.
- Eaton (Cooper Wiring): Eaton is a large diversified power management company with electrical wiring products that overlap with Cerro's distribution channels. While Eaton focuses more on wiring devices and electrical components, its scale in the electrical channel makes it a broad competitor for shelf space and contractor specification.
