What CEMCO does
CEMCO (legal name California Expanded Metal Products Co. Inc.) is a privately held US manufacturer of cold-formed steel framing and metal lath products, founded in 1974 and headquartered in City of Industry, California. The company operates four manufacturing facilities across Los Angeles, Commerce City CO, Fort Worth TX, and Pittsburg CA, equipped with 60+ state-of-the-art roll formers producing more than 1,000 SKUs from mill-certified hot-dipped galvanized steel. Its product portfolio spans structural load-bearing studs and tracks, interior non-load bearing framing systems (ViperStud, Viper-X), the Sure-Span floor joist system, CST slotted tracks, Sure-Board shear wall panels, ProX headers, shaft wall and area separation studs, plus a metal lath line (expanded, self-furred, paper-backed, Cem-Mesh, Hi-Rib) and firestop specialty products (FireRip, HOTROD, Fire Bead, Fire Gasket, Sound Gasket) backed by four intumescent firestopping patents. Products carry SFIA, ICC-ES ESR#3016, ICC-ES ESR#1623, and 200+ UL fire-rated assembly certifications, with code compliance to IBC, IRC, and CBC.
The company sells exclusively through a preferred distributor network covering the Western United States, Canada, Mexico, and the Pacific Rim, supplemented by inside/outside sales representatives, technical services, structural engineering, AIA continuing education, and an IAS-accredited testing laboratory. Pricing is quote-based and not publicly disclosed; revenue derives from hardware sales of steel framing and metal lath to commercial, institutional, mid-rise/multi-family, and residential construction end-markets. Notable enterprise project wins include SoFi Stadium (over 10 million pounds of steel), Loma Linda Hospital (4.75 million pounds), LAX Mid-Field Terminal, the US Olympic & Paralympic Museum, and The (W)rapper in Los Angeles.
CEMCO is owned by JFE Shoji America (the US arm of Japanese steel major JFE Steel) following an earlier period of ownership by the Poliquin family since 1981. Current leadership includes President and CEO Tom Porter. In February 2025 the company secured a $3.7 million patent infringement verdict and permanent injunction against KPSI Innovations; in February 2026 it opened an expanded Denver manufacturing plant. CEMCO also bundles clips and connectors through a partnership with The Steel Network (TSN) to offer an integrated framing-plus-accessories solution to contractors and distributors.
